INSPECTION PROCEDURE O-4: The door-ajar warning lamp does not illuminate/extinguish normally.
| CAUTION Whenever the ECU is replaced, ensure that the input and output signal circuits are normal.
| OPERATION The ETACS-ECU operates this function in accordance with all the door switch signals. If the door-ajar warning lamp does not work normally, the input signal circuits from all the door switches or the ETACS-ECU may be defective.
| POSSIBLE CAUSES All the door switches are defective. Malfunction of the ETACS-ECU Damaged harness wires and connectors
| DIAGNOSIS PROCEDURE
| Step 1. Check the operation of the room lamp. Check that the room lamps illuminate and extinguish normally. Q: Is the check result normal? YES: Go to Step 2. NO: Refer to Inspection Procedure O-1 "The front or rear room lamp does not illuminate or extinguish <vehicles without keyless entry system> ." Or refer to inspection procedure O-2 "The front or rear room lamp does not illuminate or extinguish <vehicles with keyless entry system> ."
| Step 2. SWS monitor data list Check the input signals below, which are related to the door-ajar warning lamp. <Selected item> ETACS ECU Driver's door: open
Item No. | Item name | Normal condition
--- | --- | ---
Item 32 | DR DOOR SW*1 | ON
FRONT DOOR SW*2
NOTE: *1 : Except for Australia *2 : Vehicles for Australia OK: Normal condition is displayed. Q: Is the check result normal? YES: Go to Step 3. NO: Refer to Inspection Procedure P-4 "The driver's door switch signal is not received <LH drive vehicles>."

System switch | Check condition
--- | ---
All of the door switches | A door is opened when all the doors are closed
OK: The MUT-II/III sounds or the voltmeter needle fluctuates. Q: Is the check result normal? YES: Go to Step 4. NO: Refer to Inspection Procedure P-14 "All the door switch signals are not received <LH drive vehicles>." Refer to Inspection Procedure P-14 "All the door switch signals are not received <RH drive vehicles>."
| Step 4. Connector check: C-05 combination meter connector Q: Is the check result normal? YES: Go to Step 5. NO: Repair the defective connector.
| Step 5. Check the door-ajar warning lamp bulb. Check the door-ajar warning lamp bulb. Q: Is the check result normal? YES: Go to Step 6. NO: Replace the door-ajar warning lamp bulb.
| Step 6. Connector check: C-217 ETACS-ECU connector Q: Is the check result normal? YES: Go to Step 7. NO: Repair the defective connector.
| Step 7. Check the wiring harness from C-217 ETACS-ECU connector (terminal Nos.53 and 71) to C-05 combination meter connector (terminal Nos.20 and 21). Q: Is the check result normal? YES: Go to Step 8. NO: Repair the wiring harness.
| Step 8. Retest the system. Replace the ETACS-ECU, and then check that the door-ajar warning lamp illuminates/extinguishes normally. Replace the ETACS-ECU. Check that the door-ajar warning lamp illuminates/extinguishes normally. Q: Is the check result normal? YES: The trouble can be an intermittent malfunction (Refer to GROUP 00 - How to Cope with Intermittent Malfunction ). NO: Replace the combination meter.
