Inspection Procedure 2: Even if Brake Pedal is Depressed, Auto-Cruise Control is not Cancelled.
COMMENTS ON TROUBLE SYMPTOM The cause is probably a malfunction of stop lamp switch or a malfunction of stop lamp circuit.
PROBABLE CAUSES Malfunction of the connector. Malfunction of the harness. Malfunction of the stop lamp switch. Malfunction of the auto-cruise control-ECU.
DIAGNOSIS PROCEDURE
STEP 1. Check the stop lamp. Q: Does the stop lamp illuminated? YES: Go to Step 6. NO: Go to Step 2.
STEP 2. Check the stop lamp switch. Refer to . Q: Is the check result normal? YES: Go to Step 3. NO: Replace the stop lamp switch (Refer to GROUP 35A - Brake Pedal ). Then go to Step 10.
STEP 3. Measure at stop lamp switch connector C-101. Disconnect stop lamp switch connector C-101 and measure at the harness side. Voltage between terminal 2 and body earth. OK: System voltage Q: Is the check result normal? YES: Go to Step 6. NO: Go to Step 4.
STEP 4. Check stop lamp switch connector C-101 and intermediate connector C-116. Q: Is the check result normal? YES: Go to Step 5. NO: Repair or replace connector. Then go to Step 10.
STEP 5. Check the harness between the relay box and stop lamp switch connector C-101. Q: Is the check result normal? YES: This malfunction is intermittent (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points ). NO: Repair harness. Then go to Step 10.
STEP 6. Measure at auto-cruise control-ECU connector C-113. Disconnect auto-cruise control-ECU connector C-113 and measure at the harness side. Voltage between terminal 4 and body earth. OK: System voltage (When brake pedal is depressed). Q: Is the check result normal? YES: Go to Step 9. NO: Go to Step 7.
STEP 7. Check auto-cruise control-ECU connector C-113, stop lamp switch connector C-101, joint connector (1) C-16 <R.H. drive vehicles only> and intermediate connector C-104 <R.H. drive vehicles only>. Q: Is the check result normal? YES: Go to Step 8. NO: Repair or replace connector. Then go to Step 10.
STEP 8. Check the harness between the stop lamp switch connector C-101 and auto-cruise control-ECU connector C-113. Q: Is the check result normal? YES: This malfunction is intermittent (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points ). NO: Repair harness. Then go to Step 10.
STEP 9. Retest the system. Q: Does a malfunction take place again? YES: Replace the auto-cruise control-ECU (Refer to ). Then go to Step 10. NO: This malfunction is intermittent (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points ).
STEP 10. Retest the system. Q: Does a malfunction take place again? YES: Return to Step 1. NO: This malfunction is eliminated.
