WIRING DIAGRAM

8B1. CHECK BRAKE SWITCH.

1. Turn ignition switch to ON.
2. Turn cruise control main switch to ON.
3. Apply parking brake securely.
4. Set select monitor in "Current Data Display & Save" mode.
5. Release the clutch pedal. (MT)
6. Depress the brake pedal and check signals for proper operation.
1. The Stop Lamp Switch shown on the display turns from "OFF" to "ON".
2. The Brake Switch shown on the display turns from "OFF" to "ON".

7. Release the brake pedal.
8. Remove connector of stop and brake switch.




9. Check circuit between brake switch terminal.

CHECK: Is resistance less than 1 resistance? (When brake pedal is released.)

YES: Go to step 8B2.

NO: Replace brake and stop light switch.

8B2: CHECK BRAKE SWITCH.




Check circuit between brake switch terminal.

CHECK: Is resistance more than 1 MOhm? (when brake pedal is depressed.)

YES: Go to step 8B3.

NO: Replace brake and stop light switch.

8B3: CHECK STOP LIGHT SWITCH.




Check circuit between stop light switch terminal.

CHECK: Is resistance more than 1 MOhm? (When brake pedal is released.)

YES: Go to step 8B4.

NO: Replace brake and stop light switch.

8B4: CHECK STOP LIGHT SWITCH.




Check circuit between stop light switch terminal.

CHECK: Is resistance less than 1 Ohm? (When brake pedal is depressed.)(MT)

YES: Go to step 8B5. (AT) Go to step 8B1.

NO: Replace brake and stop light switch.

8B5: CHECK CLUTCH SWITCH. (MT)

1. Turn ignition switch to ON.
2. Turn cruise control main switch to ON.
3. Apply parking brake securely.
4. Set select monitor in "Current Data Display & Save" mode.
5. Depress the clutch pedal and check signal for proper operation.
The Clutch/Inhibitor Switch shown on the display turns from "ON" to "OFF".
6. Disconnect connector of clutch switch.




7. Check continuity of the clutch switch.

CHECK: Is resistance less than 10 Ohm? (When clutch pedal is released.)

YES: Go to step 8B6.

NO: Replace clutch switch.

8B6: CHECK CLUTCH SWITCH. (MT)




Check continuity of the clutch switch.

CHECK: Is resistance more than 1 MOhm? (When clutch pedal is depressed.)

YES: Replace cruise control module.

NO: Replace clutch switch.

8B1: CHECK INHIBITOR SWITCH. (AT)

1. Turn ignition switch to ON.
2. Turn cruise control main switch to ON.
3. Apply parking brake securely.
4. Set select monitor in "Current Data Display & Save" mode.
5. Set the selector lever from P or N position to D position and check signal for proper operation.
The Clutch/Inhibitor Switch shown on the display turns from "ON" to "OFF".
6. Set the selector lever to P or N position.
7. Disconnect connector of inhibitor switch.




8. Check continuity of the inhibitor switch.

CHECK: Is resistance less than 10 Ohm? (When selector lever is in P or N.)

YES: Go to step 8B8.

NO: Replace inhibitor switch. Repair inhibitor switch wiring harness.

8B8: CHECK INHIBITOR SWITCH. (AT)




Check continuity of the inhibitor switch.

CHECK: Is resistance more than 1 MOhm? (When selector lever is not in P or N.)

YES: Replace cruise control module.

NO: Replace inhibitor switch. Repair inhibitor switch wiring harness.
