Note

When removing or installing the rear disc brake caliper assembly, if the piston of the brake caliper is pushed in, the clearance between the brake pad and rear disc will become large. In this condition, depressing the brake pedal may cause DTC C1214 (Hydraulic Control System Malfunction) to be stored, so check and clear DTCs after the procedure is complete.

CAUTION:


  • B006JCR

    Work procedures must be performed in an area with good ventilation (airflow) where hydrogen gas will not accumulate, and flames or other things that could act as ignition sources must not be present.

  • Accumulated hydrogen gas could ignite, resulting in a serious accident.

  • B006JFPC04
    *a When inside of piping is pressurized

    Do not install or remove any hydrogen system components without first performing depressurization procedures.

  • The highly pressurized hydrogen gas inside the hydrogen tank assembly could blow out, resulting in a serious accident.

  • B006JLTC19
    *a Manual Valve Open

    Do not perform depressurization procedures when the manual valve of the hydrogen tank assembly is open.

  • The highly pressurized hydrogen gas inside the hydrogen tank assembly could blow out, resulting in a serious accident.

  • B006JBL

    When performing depressurization, do not perform procedures by hand without wearing protective glasses and gloves.

  • The highly pressurized hydrogen gas inside the hydrogen tank assembly could blow out, resulting in a serious accident.

  • B006JJ9C01
    *a After depressurization procedures, the high pressure piping union nut that is loosened first

    After performing depressurization procedures, when first loosening the union nut of the high pressure hydrogen piping, do not loosen the union nut by hand without wearing protective glasses and gloves.

  • Even when depressurization procedures are performed, the pressurized hydrogen gas inside the high pressure hydrogen piping cannot be completely depressurized, so the highly pressurized hydrogen gas remaining in the high pressure hydrogen piping could blow out, resulting in a serious accident.

  • B006JKHC09
    *a Heavy load exceeding the weight limits or size limits of the engine lifter

    Because the hydrogen tank unit is extremely heavy, make sure to follow the work procedures described in the repair manual.

  • If work is not performed according to the procedures described in the repair manual, there is a danger that the engine lifter could drop and components could fall down.

  • B006JD5

    When hoisting up the hydrogen tank assembly, do not hoist it when not properly balanced.

  • The hydrogen tank assembly could fall, resulting in a serious accident.

  • B006JLX

    When installing or removing a compressed hydrogen gas tank immediately after discharging compressed hydrogen gas, do not touch the tank or piping if there is frost on it.

  • Touching the tank or piping while there is frost on it could result in burn-like injuries due to frostbite.

PROCEDURE


  1. PRECAUTION

    Note


    • After turning the power switch off, waiting time may be required before disconnecting the cable from the negative (-) auxiliary battery terminal. Therefore, make sure to read the disconnecting the cable from the negative (-) auxiliary battery terminal notices before proceeding with work.

      Click here

    • Place signs [HIGH PRESSURE GAS WORK IN PROGRESS - DO NOT TOUCH!], etc. to warn other technicians to be cautious. (An example sign is included, so make a copy and use it.)

      B006JJCE01
      *1 Place signs [HIGH PRESSURE GAS WORK IN PROGRESS - DO NOT TOUCH!], etc. to warn other technicians to be cautious. (An example sign is included, so make a copy and use it.)

    • When performing depressurization, do not open or close any parts of the hydrogen gas piping except for the following:

      - Adjustment bolt of the hydrogen tank assembly manual valve

      - Tank shut valve of the hydrogen tank assembly

      - No. 1 hydrogen supply regulator plug

    • When installing or removing hydrogen system components (hydrogen tank assembly, high pressure hydrogen piping, hydrogen inlet receptacle, hydrogen tube joint, hydrogen tank pressure sensor or hydrogen supply regulator assembly), to prevent strain such as twisting from being applied to the high pressure hydrogen piping, use the hydrogen tank installation and removal guide tool and remove the hydrogen tank unit from the vehicle before performing procedures.

    • Even when replacing only the No. 1 hydrogen tank assembly, or only the No. 2 hydrogen tank assembly, to prevent strain from being applied to the high pressure hydrogen piping, use the tank positioning attachment of the hydrogen tank installation and removal tool, and perform positioning of the No. 1 hydrogen tank assembly and No. 2 hydrogen tank assembly.

    • Even when not removing or installing the high pressure hydrogen piping, be careful not to pull or otherwise apply strain to the high pressure hydrogen piping.

    • Do not reuse high pressure hydrogen piping after it has been removed, because the coupling portions will not maintain their airtightness.

    • When reusable parts such as the hydrogen tank assembly valve portion, hydrogen inlet receptacle, hydrogen tube joint and hydrogen supply regulator assembly have been removed, to protect the seal portions and threaded portions from damage as well as to prevent foreign matter such as dust and metal fragments from entering through openings, cover these areas with protective tape.

    • Do not use packing tape, or any other tape that will leave residue on parts, as protective tape.

    • B006JHHC10
      *a Protective Tape
      *b Seal Portion
      *c Threaded Portion

      Protect seal portions and threaded portions as shown in the illustration.

    • To protect the seal portions and threaded portions from damage or contamination by foreign matter, remove the protective tape immediately before installation.

    • When reassembling components that have been removed, make sure that there is no foreign matter adhering to the openings.

    • After installing hydrogen system components, first perform primary leak inspection with low pressure nitrogen gas, and then fill pressurized hydrogen gas at a hydrogen station to perform secondary leak inspection. When performing secondary leak inspection, the vehicle cannot be driven to the hydrogen station under its own power, so transport it using a car carrier, etc.

    • When the vehicle is parked with the power switch off, if the FC control ECU judges that the FC stack temperature will go below 0°C (32°F), it activates the FC air compressor, hydrogen pump and FC cooling water pump for a maximum of 180 seconds and drains water from the FC stack assembly. When performing inspection or repairs with the power switch off (not on (IG) or on (READY)), disconnect the cable from the negative (-) auxiliary battery terminal before performing work.

    • When frost has formed on the hydrogen tank assembly or piping, water droplets may be formed when the frost begins to melt. If water droplets enter the tank or piping, it could result in blockage of the hydrogen piping, so do not allow water droplets to enter the tank or piping.

      Under basic conditions


      1. Set the SST (hydrogen venting tool) in an outdoor location.

        Note

        Take care that the compressed hydrogen gas that is discharged during the discharging procedure does not enter any indoor location.

    20. B006JJQ

      Other than basic conditions (when outdoor setup is not possible)


      1. When the SST (hydrogen venting tool) will be set up indoors, locate it along a wall near a window, and with the tip of the SST (upper release pipe) outdoors.

        Note

        Open windows on two sides or more, and ensure that there is adequate ventilation to prevent the compressed hydrogen gas that is discharged from collecting inside.

    21. Open the tank shut valves of the No. 1 and No. 2 hydrogen tank assemblies, and after 2 to 3 seconds, close the tank shut valves again.

      CAUTION:

      B006JJM

      • When opening the tank shut valve and applying pressure to the SST (hydrogen venting tool), stay away from the SST (flexible hose).

      • If the SST (flexible hose) comes off, you could be struck by the loose end of the SST (flexible hose), causing a serious accident.

      Note

      If the Data List item "Medium-range Hydrogen Pressure (gauge)" decreases to below 0.6 MPa (6.1 kgf/cm2, 87 psi) the tank shut valves of the No. 1 and No. 2 hydrogen tank assemblies will forcibly close.

    22. If the tank shut valves of the No. 1 and No. 2 hydrogen tank assemblies do not open, open the tank shut valves again, and after 2 to 3 seconds, close the tank shut valves.

    23. Perform preliminary leak check (using remaining piping pressure).

      Tech Tips

      Perform leak check using the pressure remaining upstream of the tank shut valve.


      1. If there are any water droplets, etc. adhering to the measurement locations, wipe them away before performing the procedure.

        Note

        Performing the measurement while any water droplets, etc. are adhering could damage the hydrogen gas detector.

      2. Using SST and a hydrogen gas detector, inspect for leaks in the locations shown in the illustration.

      SST
      09404-62010   ( 09404-06010 )

    28. Continue to monitor the Data List, and when the value of "Medium-range Hydrogen Pressure (gauge)" becomes 0.8 MPa (8.2 kgf/cm2, 116 psi), close the open/close valve of the SST (venting stand).

      Note


      • To protect the tank shut valve, make sure to first close the open/close valve of the SST (venting stand).

      • Forgetting to close the open/close valve of the SST (venting stand) and allowing the Data List item "Medium-range Hydrogen Pressure (gauge)" to decrease to below 0.6 MPa (6.1 kgf/cm2, 87 psi) will cause the tank shut valves of the No. 1 and No. 2 hydrogen tank assemblies to forcibly close.

    29. Check that the Data List item "Medium-range Hydrogen Pressure (gauge)" and the pressure on the pressure indicator of the SST (venting stand) are less than 0.8 MPa (8.2 kgf/cm2, 116 psi).

      Note


      • The pressure immediately after closing the open/close valve of the SST (venting stand) should be less than 0.8 MPa (8.2 kgf/cm2, 116 psi) for both the Data List item "Medium-range Hydrogen Pressure (gauge)" and on the pressure indicator of the SST (venting stand).

      • If either the Data List item "Medium-range Hydrogen Pressure (gauge)" or the pressure on the pressure indicator of the SST (venting stand) are 0.8 MPa (8.2 kgf/cm2, 116 psi) or greater, open the open/close valve of the SST (venting stand) and adjust the pressure.

      Tech Tips

      If the pressure immediately after closing the open/close valve of the SST (venting stand) is less than 0.8 MPa (8.2 kgf/cm2, 116 psi) for both the Data List item "Medium-range Hydrogen Pressure (gauge)" and on the pressure indicator of the SST (venting stand), then the pressurized hydrogen gas depressurizing procedure is complete.
