Diagnostic Strategies

FOREWORD

CAUTION:
- When the engine does not start or stalls and the following DTCs are not indicated, refer to engine symptom troubleshooting. (See No.3 WILL NOT CRANK [L3]) (See No.3 WILL NOT CRANK [AJ])
- If DTCs cannot be retrieved due to a security light circuit malfunction, refer to immobilizer system symptom troubleshooting. (See No.1 SECURITY LIGHT REMAINS ON OR DOES NOT ILLUMINATE)

NOTE:
- When the immobilizer system is defective, the engine cannot be started.
- If engine condition is normal but security light stays on, inspect for short circuit between security light. Repair or replace the wiring harness if necessary.
- The vehicle may fail to start or a DTC may be stored in the PCM if the following occurs:
- If a large, metal object is close to a valid key
- If an electrical device is close to a valid key
- If two or more valid keys are on the same key ring
- If any malfunction cannot be identified, verify that no metal object or electrical device is on the key ring.
- The security light repeatedly displays a DTC 10 times when the ignition switch is in the ON position.

1. Turn the ignition switch to the ON position.
- If there is any malfunction, the security light flashes rapidly for approx. 1 minute and starts displaying a DTC.
- If there is no malfunction, the security light illuminates for approx. 3 seconds and goes off.

2. Verify the security light condition and read the DTC according to security light flashing pattern.




3. Connect the SST (WDS) to the vehicle DLC-2 16-pin connector.
4. Verify the DTC with the SST (WDS).
5. If a DTC is indicated, perform on-board diagnostic referring to the DTC table.

PID/Data Monitor and Record Procedure
1. Connect the SST (WDS) to the vehicle DLC-2 16-pin connector.
