| SECURITY-ALARM SYSTEM

INSPECTION PROCEDURE O-1: The security alarm is not armed.
| 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) Alternatively, it is possible that "SECURITY ALM" was set to "W/O FUNCTION" 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 "SECURITY ALM" is set to "HORN/HAZARD" or "HAZARD" by using the adjustment function. Q: Is the check result normal? YES: Go to Step 2. NO: Set "SECURITY ALM" to "HORN/HAZARD" or "HAZARD" by 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. Confirm communication data by using the SWS monitor. Check the SWS communication signal from the ignition switch (ACC) to the ETACS-ECU. <Selected item> ETACS ECU Ignition switch (ACC)
Item No. | Item name | Normal conditions
--- | --- | ---
Item 31 | IG SW(ACC) | ON
OK: Normal condition is displayed. Q: Is the check result normal? YES: Go to Step 4. NO: Refer to inspection procedure P-1 "The ignition switch (ACC) signal is not received ."
| Step 4. Check the ETACS SW data by using the SWS monitor. Check the ETACS-ECU signal from the key reminder switch. Ignition switch: OFF (key inserted)
Item No. | Item name | Normal conditions
--- | --- | ---
Item 03 | KEY REMIN SW | OFF
OK: Normal condition is displayed. Q: Is the check result normal? YES: Go to Step 5. NO: Refer to inspection procedure P-10 "The key reminder switch signal is not received ."
| Step 5. Connector check: C-122 security alarm indicator lamp connector Q: Is the check result normal? YES: Go to Step 6. NO: Repair the defective connector.
| Step 6. Check the security alarm indicator lamp. Check that the security alarm indicator lamp illuminates. Q: Is the check result normal? YES: Go to Step 7. NO: Replace the security alarm indicator lamp.
| Step 7. 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 9. NO: Go to Step 8.
| Step 8. 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 9. Connector check: C-219 ETACS-ECU connector Q: Is the check result normal? YES: Go to Step 10. NO: Repair the defective connector.
| Step 10. 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 11. NO: Repair the wiring harness.
| Step 11. 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.
