-
DTCs are recorded in the PCM and keyless control module when a malfunction is detected. The stored DTCs can be verified using the flashing
pattern of the security light and M-MDS. There are some DTCs which cannot be verified using the security light. Verify the DTCs that were
detected using the M-MDS prior to beginning the servicing. See: Testing and Inspection/Reading and Clearing Diagnostic Trouble Codes/DTC
Inspection/Immobilizer System (Advanced Keyless Entry And Push Button Start System)
-
If more than one DTC is detected, the security light only displays the DTC with the lowest number. Begin repairs based on the DTC displayed by
the security light. All DTCs can be read by the M-MDS.
-
It is possible for several DTCs to be displayed for a one malfunction cause. Erase the DTCs after one repair and then re-inspect the DTCs.
-
If immobilizer system DTCs are not recorded even if the engine cannot be started, perform symptom troubleshooting. See: Engine, Cooling and
Exhaust/Engine/Testing and Inspection/Symptom Related Diagnostic Procedures/No.3 Will Not Crank See: Engine, Cooling and
Exhaust/Engine/Testing and Inspection/Symptom Related Diagnostic Procedures/No.3 Will Not Crank
-
The PID/data monitor function can be used to verify the number of key ID numbers programmed for a single vehicle. (See See: Accessories and
Optional Equipment/Antitheft and Alarm Systems/Testing and Inspection/Pinout Values and Diagnostic Parameters/PID/Data Monitor
Table/Immobilizer System (Advanced Keyless Entry And Push Button Start System)].)
NOTE:
-
Due to the possibility that the engine cannot be started because transmission between the key and the vehicle is obstructed, do not allow the
following items to contact the key ring.
-
Any metallic object
-
Spare keys or keys for other vehicles equipped with an immobilizer system
-
Any electronic device, or any credit or other card with magnetic strips
