| SECURITY-ALARM SYSTEM

INSPECTION PROCEDURE O-1: The security alarm is not armed (the security alarm indicator lamp does not illuminate).
| CAUTION Whenever the ECU is replaced, ensure that the input and output signal circuits are normal.
| COMMENTS ON TROUBLE SYMPTOM If the security alarm does not work normally, the input signal circuits to the components below and security alarm indicator lamp or the ETACS-ECU may be defective. Keyless entry transmitter Key reminder switch Ignition switch (ACC) In addition, it is possible that the security alarm function has been disabled by using the adjustment function.
| POSSIBLE CAUSES Malfunction of the security alarm indicator lamp Malfunction of the keyless entry transmitter Malfunction of the key reminder switch Malfunction of the ETACS-ECU Damaged harness wires and connectors
| DIAGNOSIS PROCEDURE
| Step 1. Check the adjustment function. Check that the security alarm function has been enabled by using the adjustment function. Q: Is the check result normal? YES: Go to Step 2. NO: Enable the security alarm function using the adjustment function. (Refer to .)
| Step 2. Check the keyless entry system. Check that the keyless entry system works normally. Q: Is the check result normal? YES: Go to Step 3. NO: Refer to inspection procedure E-1 "Keyless entry system does not work ."
| Step 3. Pulse check Check the input signals which are related to the security alarm.
System switch | Check conditions
--- | ---
Ignition switch (ACC) | When turned from the LOCK (OFF) position to the ACC position
Key reminder switch | When the inserted ignition key is pulled out
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: Are the check result normal? All the signals are received normally.: Go to Step 4. The ignition switch (ACC) signal is not received.: Refer to Inspection Procedure P-1 "The ignition switch (ACC) signal is not received." . The key reminder switch signal is not received.: Refer to inspection procedure P-10 "The key reminder switch signal is not received ." The keyless entry transmitter switch signal is not received.: Refer to Inspection Procedure P-16 "Each switch signal of the keyless entry transmitter is not received."
| Step 4. Connector check: C-122 security alarm indicator lamp connector Q: Is the check result normal? YES: Go to Step 5. NO: Repair the defective connector.
| Step 5. Check the security alarm indicator lamp. Check that the security alarm indicator lamp illuminates. Q: Is the check result normal? YES: Go to Step 6. NO: Replace the security alarm indicator lamp.
| Step 6. Measure the voltage at C-122 security alarm indicator lamp connector. Disconnect the connector, and measure at the wiring harness side. Voltage between C-122 security alarm indicator lamp connector terminal 1 and body earth OK: Battery positive voltage Q: Is the check result normal? YES: Go to Step 8. NO: Go to Step 7.
| Step 7. Check the wiring harness between C-122 security alarm indicator lamp connector terminal No.1 and fusible link (1). NOTE: Prior to the wiring harness inspection, check intermediate connectors A-14, C-125, joint connector C-02 and junction block connectors C-202, C-204 and repair if necessary. Check the power supply line for open or short circuit. 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: Repair the wiring harness.
| Step 8. Connector check: C-219 ETACS-ECU connector Q: Is the check result normal? YES: Go to Step 9. NO: Repair the defective connector.
| Step 9. Check the wiring harness between C-219 ETACS-ECU connector terminal No. 74 and C-122 security alarm indicator lamp connector terminal No.2. Check the power supply line for open or short circuit. Q: Is the check result normal? YES: Go to Step 10. NO: Repair the wiring harness.
| Step 10. Retest the system. Check that the security alarm 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.
