| 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 on 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 ECUS 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 the ETACS-ECU is not possible ."
| Step 2. Use the SWS monitor to examine the keyless entry system for signal reception. Check the condition of the keyless entry transmitter.
Operation switch | Normal conditions (received signal)
--- | ---
LOCK | LOCK
UNLOCK | UNLOCK
| OK: By operating the switch as shown in the table above, relevant normal conditions are displayed. Q: Is the check result normal? YES: Go to Step 3. NO: Refer to inspection procedure P-16 "Each switch signal of the keyless entry transmitter is not received ."
| Step 3. Confirm communication data by using the SWS monitor. Check the ETACS-ECU signal, which is related to the central door locking system. <Selected item> ETACS Each door: Closed to open
Item No. | Item name | Normal conditions
--- | --- | ---
Item 38 | SECURITY ALRM | From OFF to ON
OK: Normal condition is displayed. Q: Is the check result normal? YES: Go to Step 4. NO: Refer to inspection procedure P-13 "All the door switch signals are not received ."
| Step 4. 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.
