ABS indicator, brake system indicator (red), VSA indicator, and brake system indicator (amber) do not go off 

  1. All DTCs check

    -1. Turn the vehicle to the ON mode.

    -2. All DTCs check with the HDS.

    All DTCs

    Are there DTCs indicated?

    YES 

    The fuse is OK. Reinstall the fuse, then go to step 3.

    NO 

    Replace the fuse. Turn the vehicle to the ON mode, then the OFF (LOCK) mode. If the fuse blows again, repair the short to body ground on the No. A41 fuse circuit.

  3. Fuse check 2

    -1. Check the following fuse.

  4. Open wire check (IG1 ABS/VSA (or IG1 VSA/ABS) line)

    -1. Turn the vehicle to the OFF (LOCK) mode.

    -2. Disconnect the following connector.

    VSA modulator-control unit 46P connector

    -3. Turn the vehicle to the ON mode.

    -4. Measure the voltage between test points 1 and 2.

    Test condition Vehicle ON mode
      VSA modulator-control unit 46P connector: disconnected
    Test point 1 VSA modulator-control unit 46P connector No. 13 
    Test point 2 Body ground

    Is there battery voltage?

    YES 

    The IG1 ABS/VSA (or IG1 VSA/ABS) wire is OK. Go to step 5.

    NO 

    Repair an open in the wire between the No. A41 fuse and the VSA modulator-control unit.

  5. Open wire check (+B ABS/VSA FSR line)

    -1. Turn the vehicle to the OFF (LOCK) mode.

    -2. Measure the voltage between test points 1 and 2.

    Test condition Vehicle OFF (LOCK) mode
      VSA modulator-control unit 46P connector: disconnected
    Test point 1 VSA modulator-control unit 46P connector No. 1 
    Test point 2 Body ground

    Is there battery voltage?

    YES 

    The +B ABS/VSA FSR wire is OK. Go to step 6.

    NO 

    Repair an open in the wire between the No. A2-3 fuse and the VSA modulator-control unit.

  6. Open wire check (GND line)

    -1. Check for continuity between test points 1 and 2.

    Test condition Vehicle OFF (LOCK) mode
      VSA modulator-control unit 46P connector: disconnected
    Test point 1 VSA modulator-control unit 46P connector No. 4 
    Test point 2 Body ground

    Is there continuity?

    YES 

    The GND wire is OK. Go to step 7.

    NO 

    Repair an open in the wire between the VSA modulator-control unit and body ground (G401).

  7. Open wire check (F-CAN A_H, F-CAN A_L lines)

    -1. Disconnect the following connectors.

    Gauge control module connector A (32P)

    -2. Check for continuity between test points 1 and 2.

    Test condition Vehicle OFF (LOCK) mode
      VSA modulator-control unit 46P connector: disconnected
      Gauge control module connector A (32P): disconnected
    Test point 1 Gauge control module connector A (32P) No. 20
    Test point 2 VSA modulator-control unit 46P connector No. 20 
    Test point 1 Gauge control module connector A (32P) No. 21
    Test point 2 VSA modulator-control unit 46P connector No. 21 

    Is there continuity?

    YES 

    Check for loose terminals in the VSA modulator-control unit 46P connector. If the symptom/indication is still present, replace the VSA modulator-control unit .

    NO 

    Repair an open in the wire between the VSA modulator-control unit and the gauge control module.
