REPLACEMENT ).

NO -Go to step 8.

8. Turn the ignition switch to LOCK (0).
9. Disconnect the gauge control module (tach) 36P connector.

10. Check for continuity between parking brake switch 1P connector terminal No.

1 and body ground.

Fig. 59: Checking Continuity Between Parking Brake Switch 1P
Connector Terminal No. 1 And Body Ground

Is there continuity?

YES -Repair short to body ground in the wire between the gauge control
module (tach) and the parking brake switch.

NO -Check for loose terminals in the gauge control module (tach) 36P
connector. If necessary, substitute a known-good gauge control module (tach),
then go to step 1 and recheck. If it is OK, replace the original gauge control
module (tach) (see REPLACEMENT ).

VSA activation indicator does not go off, and no DTCs are stored

1. Turn the ignition switch ON (II).
2. Check the VSA activation indicator for several seconds when the ignition

switch is turned ON (II).

Does the indicator come on then go off?

YES -Intermittent failure, the system is OK at this time. Check for loose
terminals between the VSA OFF switch 5P connector, the gauge control
module (tach) 36P connector, and the VSA modulator-control unit 37P
connector. Refer to

INTERMITTENT FAILURES TROUBLESHOOTING

(see ).

NO -Go to step 3.

3. Check the VSA OFF SWITCH in the VSA DATA LIST with the HDS while

pushing the VSA OFF switch.

Does the indicator change from ON (OFF) to OFF (ON)?

YES -Do the gauge control module troubleshooting (see SELF-
DIAGNOSTIC FUNCTION ).

NO -Go to step 4.

4. Turn the ignition switch to LOCK (0).
5. Check the VSA OFF switch (see VSA OFF SWITCH TEST ).

Is the VSA off switch OK?

YES -Go to step 6.

NO -Replace the VSA OFF switch (see VSA OFF SWITCH TEST ).

6. Disconnect the gauge control module (tach) 36P connector.
7. Disconnect the VSA OFF switch 5P connector.
8. Check for continuity between VSA OFF switch 5P connector terminal No. 2

and body ground.

Terminal No. 2 And Body Ground

Is there continuity?

YES -Repair short to body ground in the wire between the gauge control
module (tach) and the VSA OFF switch.

NO -Substitute a known-good VSA modulator-control unit, then go to step 1
and recheck. If it is OK, replace the original VSA modulator-control unit (see
VSA MODULATOR-CONTROL UNIT REMOVAL AND
INSTALLATION ).

ABS indicator, brake system indicator, and VSA indicator do not go off at same time

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 (tach) 36P connector and the VSA
modulator-control unit 37P connector. Refer to INTERMITTENT

NOTE:

Check for gauge DTCs with the HDS (see WIRE COLOR
CODES ). If goluges DTCs are stored, troubleshoot those
DTCs first.

Body Ground

Is there continuity?

YES -Repair short to body ground in the wire between the ECM/PCM, the
gauge control module (tach), the data link connector (DLC), the SRS unit, the
EPS control unit (if equipped), the TPMS control unit (if equipped), and the
