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 timeNOTE: Check for gauge DTCs with the HDS if gauge DTCs are stored, troubleshoot those DTCs first.
1. Release the parking brake.
2. Turn the ignition switch ON (II).
3. Check the ABS indicator, brake system indicator and the VSA indicator for several seconds when the ignition switch is turned ON (II).
Do the indicators come on then go off?
YES - Intermittent failure, the system is OK at this time. Check for loose terminals between the gauge control module connector A (30P) and the VSA modulator-control unit 37P connector. Refer to intermittent failures troubleshooting.
NO - Go to step 4.
4. Turn the ignition switch OFF.
5. Short the SCS line with the HDS.
6. Disconnect ECM/PCM connector E (31P).
7. Disconnect the HDS from the data link connector (DLC).
8. Disconnect the gauge control module connector A (30P).
9. Disconnect the VSA modulator-control unit 37P connector, SRS unit connector A (28P), AcuraLink unit (XM receiver) connector A (20P), TPMS control unit connector B (20P) and the navigation control unit connector A (20P) if equipped.
10. Check for continuity between body ground and VSA modulator-control unit 37P connector terminals No. 1, and No. 15 individually.
Is there continuity?
YES - Repair Short to body ground on the appropriate wire.
NO - Go to step 11.
11. Check for continuity between VSA modulator-control unit 37P connector terminals No. 1 and No. 15.
Is there continuity?
YES - Repair the Short in the wire between VSA modulator-control unit 37P connector terminals No. 1 (CAN-L line) and No. 15 (CAN-H line).
NO - Go to step 12.
12. Check for continuity between VSA modulator-control unit 37P connector terminal and gauge control module connector A (30P) terminal (see table).
Is there continuity?
YES - Check for loose terminals in the gauge control module connector A (30P) if necessary, substitute a known-good gauge control module, then Go to step 1 and recheck. If it is OK, replace the original gauge control module if DTCs are indicated, replace the VSA modulator-control unit.
NO - Repair open in the wire between the gauge control module and the VSA modulator-control unit.
