  2. INSPECT BATTERY VOLTAGE


    1. Measure the battery voltage.

      Standard voltage
      11 to 14 V

    2. Using the parts location and system diagram, check the system for blown-out fuses, open or short circuits in the wire harness(es) and connectors that are not properly connected by performing a visual check.

      Tech Tips

      If the voltage is 11 V or less, replace or recharge the auxiliary battery before proceeding to the next step.

      Front view of wire harness connector

      (to Driving Support ECU Assembly)

      Check driving support ECU assembly.

      Note

      As the connector may be damaged if a load of more than 10 kg (22 lb) is applied to it, do not apply any more load than necessary to the connector.


      1. Disconnect the driving support ECU assembly connector.

      2. Measure the voltage according to the value(s) in the table below.

        Note

        DTCs may be output when connectors are disconnected during inspection. Therefore, make sure to clear the DTCs using the GTS once the inspection has been completed.

        Standard Voltage
        Tester Connection Switch Condition Specified Condition
        G168-7 (B) - Body ground Ignition switch ON

        11 to 14 V*1

        9.5 to 14 V*2
        G168-7 (B) - Body ground Ignition switch off Below 1 V
        *1: w/o Stop and Start System
        *2: w/ Stop and Start System

      3. Measure the resistance according to the value(s) in the table below.

        Standard Resistance
        Tester Connection Condition Specified Condition
        G168-28 (GND) - Body ground Always Below 1 Ω

  5. CHECK FOR DTC


    1. Check for DTCs and note any codes that are output.

      Click here


      Body Electrical > Pre-Crash 2 > Trouble Codes

    2. Clear the DTCs.

      Click here


      Body Electrical > Pre-Crash 2 > Clear DTCs

    3. Recheck for DTCs. Try to reproduce the DTCs by duplicating the conditions indicated by the DTCs.
