3. Clutch Pedal Is Depressed, Auto-Cruise Control Not Cancelled

INSPECTION PROCEDURE 3: When the Clutch Pedal is Depressed, Auto-cruise Control is not Canceled.

Clutch Pedal Position Switch Circuit:

CIRCUIT OPERATION
This circuit indicates the operation status of the clutch pedal position switch. When the clutch pedal position switch is ON (clutch pedal is depressed) the voltage of auto-cruise control-ECU terminal number 13 will indicate 0 volt.

TECHNICAL DESCRIPTION (COMMENT)
The cause is probably a malfunction of the clutch pedal position switch circuit.

TROUBLESHOOTING HINTS
- Malfunction of the clutch pedal position switch.
- Damaged harness or connector. Malfunction of the auto-cruise control-ECU.

DIAGNOSIS







STEP 1. Check the clutch pedal position switch.

1. Disconnect clutch pedal position switch connector C-01.
2. The check for continuity should be made at terminals 1 and 2 of the clutch pedal position switch.





Q: Is the continuity meet the table above?

YES: Go to Step 2.
NO: Replace the clutch pedal position switch. (Refer to Clutch). Go to Step 6.







STEP 2. Measure the signal voltage at auto-cruise control-ECU connector C-21 by backprobing.

1. Do not disconnect auto-cruise control switch connector C-21.
2. Turn the ignition switch to the ON position.
3. Measure the voltage between auto-cruise control-ECU connector C-21 terminal 13 and ground by backprobing.
- The voltage should measure 0.5 volt or less. (When clutch pedal is depressed).
- The voltage should measure battery positive voltage. (When clutch pedal is not depressed).
4. Turn the ignition switch to the LOCK (OFF) position.

Q: Are all of the measured voltages satisfied?

YES: Check that the malfunction is eliminated. If the malfunction is eliminated, it can be assumed that this malfunction is intermittent. (Refer to How to Use Troubleshooting/Inspection Service Points How to Cope with Intermittent Malfunction). If the malfunction is not eliminated, replace the auto-cruise control-ECU, and then go to Step 6.
NO: Go to Step 3.










STEP 3. Check clutch pedal position switch connector C-01 auto-cruise control-ECU connector C-21 and intermediate connector C-209 for loose, corroded or damaged terminals, or terminals pushed back in the connector.

Q: Are the connectors and terminals in good condition?

YES: Go to Step 4.
NO: Repair or replace the faulty connector (Refer to Harness Connector Inspection). Go to Step 6.







STEP 4. Check the harness wire between clutch pedal position switch connector C-01 terminal 2 and auto-cruise control-ECU connector C-21 terminal 13 for damage.

Q: Is the harness wire in good condition?

YES: Go to Step 5.
NO: Repair the damaged harness wire. Go to Step 6.




STEP 5. Check the harness wire between clutch pedal position switch connector C-01 terminal I and ground for damage.

Q: Is the harness wire in good condition?

YES: It can be assumed that this malfunction is intermittent. (Refer to How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunction). Go to Step 6.
NO: Repair the damaged harness wire. Go to Step 6.

STEP 6. Check that the malfunction is eliminated.

Q: Is the malfunction eliminated?

YES: This procedure is complete.
NO: Go to Step 1.
