[54D] SMART WIRING SYSTEM (SWS) NOT USING SWS MONITOR <Except for Hong Kong spec.> - - SYMPTOM PROCEDURES - KEYLESS ENTRY SYSTEM - INSPECTION PROCEDURE E-3: Encrypted code cannot be registered. | PRINT PAGE / INDEX / PRIOR / NEXT

INSPECTION PROCEDURE E-3: Encrypted code cannot be registered.
| CAUTION Whenever the ECU is replaced, ensure that the input and output signal circuits are normal.
| COMMENTS ON TROUBLE SYMPTOM If the encrypted code registration mode is not entered, the key reminder switch, the hazard warning lamp switch or the ETACS-ECU may be defective. If the registration is not possible although the registration mode is not entered, the keyless entry transmitter or the ETACS-ECU may be defective.
| POSSIBLE CAUSES Malfunction of the key reminder switch Malfunction of the hazard warning lamp switch Malfunction of the keyless entry transmitter Malfunction of the ETACS-ECU Damaged harness wires and connectors
| DIAGNOSIS PROCEDURE
| Step 1. Check the encrypted code registration mode. Check that the encrypted code registration mode is entered. Q: Is the check result normal? YES: Go to Step 3. NO: Go to Step 2.
| Step 2. Pulse check Check the input signals below which are related to the encrypted code of the keyless entry transmitter.
System switch | Check condition
--- | ---
Key reminder switch | When the inserted ignition key is pulled out
Hazard warning lamp switch | When the switch is turned from off to on
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-10 "The key reminder switch signal is not received ." The hazard warning lamp switch signal is not received.: Refer to Inspection Procedure P-11 "The hazard warning lamp switch signal is not received ." The keyless entry transmitter switch signal is not received.: Refer to Inspection Procedure P-15 "Each switch signal of the keyless entry transmitter is not received ."
| Step 3. Retest the system. Check that the encrypted code can be registered. 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.
