| KEYLESS ENTRY SYSTEM

INSPECTION PROCEDURE E-1: Keyless entry system does not work.
| CAUTION Whenever the ECU is replaced, ensure that the input and output signal circuits are normal.
| COMMENTS ON TROUBLE SYMPTOM If the keyless entry system does not work normally, the input signal circuits to the components below or the ETACS-ECU may be defective. Key reminder switch All of the door switches Keyless entry transmitter Driver's door lock actuator
| POSSIBLE CAUSES Malfunction of the key reminder switch Malfunction of the door switches Malfunction of the keyless entry transmitter Malfunction of the driver's door lock actuator Malfunction of the ETACS-ECU Damaged harness wires and connectors
| DIAGNOSIS PROCEDURE
| Step 1. ECU check by using the SWS monitor Check that the power supply and earth lines to the ETACS-ECU and the SWS communication lines are normal. Ignition switch: OFF ECU TO BE CHECKED ETACS ECU OK: "OK" is displayed on the "ETACS ECU" menu. Q: Is the check result normal? YES: Go to Step 2. NO: Refer to Inspection Procedure A-3 "Communication with ETACS-ECU is not possible ."
| Step 2. Pulse check Check the input signals below which are related to the keyless entry system.
System switch | Check condition
--- | ---
Key reminder switch | When the inserted ignition key is pulled out
All of the door switches | A door is opened when all the doors are closed
Driver's door lock actuator switch | When the driver's key cylinder or inside lock knob is unlocked or locked
Keyless entry transmitter switch | When the switch is turned from off to on
OK: The MUT-II/III sounds or the voltmeter needle fluctuates. Q: Is the check result normal? All the signals are received normally.: Go to Step 3. The key reminder switch signal is not received.: Refer to Inspection Procedure P-12 "The key reminder switch signal is not received ." All the door switch signals are not received.: 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>." The driver's door lock actuator switch signal is not received.: Refer to Inspection Procedure P-15 "The driver's door lock actuator signal is not received <LH drive vehicles>." Refer to Inspection Procedure P-15 "The driver's door lock actuator signal is not received <RH drive vehicles>." The keyless entry transmitter switch signal is not received.: Refer to Inspection Procedure P-17 "Each switch signal of the keyless entry transmitter is not received ."
| Step 3. Retest the system. Check the keyless entry system works 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 ETACS-ECU.
