Inspection Procedure 7: When the Auto-Cruise Control MAIN Switch is Turned ON, the Auto-Cruise Control Indicator Lamp dose not Illuminate. (However, the Auto-Cruise Control in Normal).
COMMENTS ON TROUBLE SYMPTOM There may be a burnt-out indicator bulb or a malfunction of the auto-cruise control indicator lamp circuit.
PROBABLE CAUSES Burnt-out indicator bulb. Malfunction of the connector. Malfunction of the harness. Malfunction of the auto-cruise control-ECU.
DIAGNOSIS PROCEDURE
STEP 1. Check the auto-cruise control indicator bulb. Remove the combination meter (Refer to GROUP 54 - Combination Meter Assembly ), and check the auto-cruise control indicator bulb. Q: Is the check result normal? YES: Go to Step 2. NO: Replace the indicator bulb (Refer to GROUP 54A - Combination Meter ). Then go to Step 9.
STEP 2. Measure at combination meter connector C-04. Disconnect combination meter connector C-04 and measure at the harness side. Ignition switch: ON Voltage between terminal 42 and body earth. OK: System voltage Q: Is the check result normal? YES: Go to Step 5. NO: Go to Step 3.
STEP 3. Check combination meter connector C-04 and junction block connector C-205. Q: Is the check result normal? YES: Go to Step 4. NO: Repair or replace connector. Then go to Step 9.
STEP 4. Check the harness between the junction block connector C-205 and combination meter connector C-04. 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 9.
STEP 5. Measure at auto-cruise control-ECU connector C-113. Do not disconnect auto-cruise control-ECU connector C-113 and measure at the backprobing. Ignition switch: ON Auto-cruise control MAIN switch: ON Voltage between terminal 15 and body earth. OK: System voltage Q: Is the check result normal? YES: Go to Step 8. NO: Go to Step 6.
STEP 6. Check combination meter connector C-05, auto-cruise control-ECU connector C-113 and intermediate connector C-104 <R.H. drive vehicles only>. Q: Is the check result normal? YES: Go to Step 7. NO: Repair or replace connector. Then go to Step 9.
STEP 7. Check the harness between the combination meter connector C-05 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 9.
STEP 8. Retest the system. Q: Does a malfunction take place again? YES: Replace the auto-cruise control-ECU (Refer to ). Then go to Step 9. NO: This malfunction is intermittent (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points ).
STEP 9. Retest the system. Q: Does a malfunction take place again? YES: Return to Step 1. NO: This malfunction is eliminated.
