SIDE MONITOR SYSTEM "CHK" message(s) are displayed on the SIGNAL CHECK screen.

DESCRIPTION

On the [Signal Check] screen, it is possible to check if the state of signals sent to the parking assist ECU is normal Click here.

Tech Tips


  • On the [Signal Check] screen, "OK" (blue) is displayed for items with a normal inspection result and input state.

  • On the [Signal Check] screen, "CHK" (red) or incorrect vehicle specification is displayed for items with an abnormal inspection result and input state.

  • Displayed items may differ depending on the specifications.

INSPECTION PROCEDURE

Note


  • When "System initializing" is displayed on the display and navigation module display after the cable is disconnected from the negative (-) battery terminal, correct the steering angle neutral point Click here.

  • Depending on the parts that are replaced or operations that are performed during vehicle inspection or maintenance, calibration of other systems as well as the side monitor system may be needed Click here.

  • Inspect the fuses for circuits related to this system before performing the following inspection procedure.

PROCEDURE

  2. READ VALUE USING INTELLIGENT TESTER


    1. Connect the intelligent tester to the DLC3.

    2. Turn the engine switch on (IG).

    3. Turn the intelligent tester on.

    4. Enter the following menus: Chassis / Parking Assist Monitor System / Data List.

    5. Read the Data List according to the display on the intelligent tester.

      (Spiral Cable with Sensor Sub-assembly)
      *b Steering Pad Switch Assembly Side
      *c Vehicle Side

      Disconnect the F101 spiral cable with sensor sub-assembly connector.

    3. After setting the spiral cable with sensor sub-assembly to the center position, rotate the spiral cable with sensor sub-assembly 2.5 times clockwise. Then while rotating the spiral cable with sensor sub-assembly 5 times counterclockwise, measure the resistance as shown in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      z13-8 (+DP) - F101-3 (+DP) Always Below 1 Ω
      z13-9 (EAU) - F101-4 (EAU) Always Below 1 Ω
      z13-8 (+DP) - Body ground Always 10 kΩ or higher
      z13-9 (EAU) - Body ground Always 10 kΩ or higher

      Note


      • The spiral cable with sensor sub-assembly is an important part of the SRS airbag system. Incorrect removal or installation of the spiral cable with sensor sub-assembly may prevent the airbag from deploying. Refer to the pages shown in the brackets.

      • As the spiral cable with sensor sub-assembly may break, do not rotate the spiral cable with sensor sub-assembly more than the specified amount.

  5. CHECK HARNESS AND CONNECTOR


    1. Disconnect the F101 spiral cable with sensor sub-assembly connector.

    2. Disconnect the F104 parking assist ECU assembly connector.

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

      Standard Resistance
      Tester Connection Switch Condition Specified Condition
      F104-7 (BLSW) - F101-3 (+DP) Always Below 1 Ω
      F101-4 (EAU) - Body ground Always Below 1 Ω
