VSA System Symptom Troubleshooting - ABS indicator, brake system indicator, and VSA indicator do not go off at the same time

ABS indicator, brake system indicator, and VSA indicator do not go off at the same time
  1. Turn the ignition switch to LOCK (0).
  1. Check the No. 11 (7.5 A) fuse in the driver's under-dash fuse/relay box.
Is the fuse blown?
YES -
Go to Step 3 .
NO -
Reinstall the checked fuse, then go to Step 6 .
  1. Check for continuity between VSA modulator-control unit 36P connector terminal No. 30 and body ground.
Is there continuity?
YES -
Repair short to body ground in the wire between the No. 11 (7.5 A) fuse in the driver's under-dash fuse/relay box and the VSA modulator-control unit or the yaw rate-lateral/longitudinal acceleration sensor.■
NO -
Install the new No. 11 (7.5 A) fuse in the driver's under-dash fuse/relay box, then go to Step 7 .
  1. Turn the ignition switch to ON (II).

  1. Measure the voltage between VSA modulator-control unit 36P connector terminal No. 30 and body ground.
Is there battery voltage?
YES -
Go to Step 9 .
NO -
Repair open in the wire between the No. 11 (7.5 A) fuse in the driver's under-dash fuse/relay box and the VSA modulator-control unit.■
  1. Turn the ignition switch to LOCK (0).

  1. Check for continuity between VSA modulator-control unit 36P connector terminal No. 35 and body ground.
Is there continuity?
YES -
Go to Step 11 .
NO -
Repair open in the wire between the VSA modulator-control unit and body ground (G402 *1 , G203 *2 ).■
*1: LHD model
*2: RHD model

  1. Measure the voltage between VSA modulator-control unit 36P connector terminal No. 12 and body ground.
Is there battery voltage?
YES -
Go to Step 12 .
NO -
Repair open in the wire between the No. 37 (30 A) fuse in the under-hood fuse/relay box and the VSA modulator-control unit.■
  1. Disconnect the gauge control module 32P connector.

  1. Check for continuity between the VSA modulator-control unit 36P connector terminal and gauge control module 32P connector terminal (see table).

    No. 1
    No. 29
    CAN-H
    No. 14
    No. 30

Is there continuity?
YES -
Go to Step 14 .
NO -
Repair open in the wire between the gauge control module and the VSA modulator-control unit.■
  1. Reconnect all connectors.
  1. Turn the ignition switch to LOCK (0), then turn it to ON (II) again.
  1. Check the ABS indicator, brake system indicator and the VSA indicator for several seconds when the ignition switch is turned to ON (II).
Do the indicators come on then go off?
YES -
If the VSA modulator-control unit was updated, troubleshooting is complete. If the VSA modulator-control unit was substituted, replace the original VSA modulator-control unit.
NO -
Check for loose terminals in the VSA modulator-control unit 36P connector. If the VSA modulator-control unit was updated, substitute a known-good VSA modulator-control unit, then retest. If the VSA modulator-control unit was substituted, go to Step 1 .
