Note

• Perform the following if the security light stays on:

― If engine stalls, go to symptom troubleshooting “NO.7 ENGINE RUNS ROUGH/ROLLING IDLE.” (See NO.7 ENGINE RUNS ROUGH/ROLLING IDLE [WL-3].) (See NO.8 ENGINE RUNS ROUGH/ROLLING IDLE [WL-C, WE-C].)

― If engine will not start, go to symptom troubleshooting “NO.5 CRANKS NORMALLY BUT WILL NOT START.” (See NO.5 CRANKS NORMALLY BUT WILL NOT START [WL-3]) (See NO.6 CRANKS NORMALLY BUT WILL NOT START [WL-C, WE-C].)

― If engine condition is normal but light stays on, inspect for continuity between the following wiring harness and body ground: security light and immobilizer unit connector terminal M. Repair or replace the wiring harness.

Note

• If DTC 25 and the other DTC are indicated, go to DTC 25 first and then go to the other DTC.

Note

• Perform the following if the security light stays on:

― If engine stalls, go to symptom troubleshooting “NO.4 ENGINE STALLS‐AFTER START/AT IDLE”. (See NO.4 ENGINE STALLS-AFTER START/AT IDLE [WLT-1, WLT-2].)

― If engine will not start, go to symptom troubleshooting “NO.5 CRANKS NORMALLY BUT WILL NOT START”. (See NO.5 CRANKS NORMALLY BUT WILL NOT START [WLT-1, WLT-2].)
