Diagnostic Procedure

STEP

INSPECTION

ACTION

1

VERIFY NUMBER OF REGISTERED KEYS

•  Using the M-MDS, perform the PID/data monitor inspection and confirm the number of registered keys.
(See PID/DATA MONITOR TABLE [IMMOBILIZER SYSTEM (KEYLESS ENTRY SYSTEM)].)

•  Are one or more keys registered?

Yes

Go to the next step.

No

Go to Step 3.

2

VERIFY NUMBER OF REGISTERED KEYS

•  Using the M-MDS, perform the PID/data monitor inspection and confirm the number of registered keys.
(See PID/DATA MONITOR TABLE [IMMOBILIZER SYSTEM (KEYLESS ENTRY SYSTEM)].)

•  Are eight keys registered?

Yes

Using the M-MDS, clear the key ID numbers as necessary, then go to the next step.

No

Go to the next step.

3

INSPECT INSTRUMENT CLUSTER

•  Using the M-MDS, register the key ID number.
(See IMMOBILIZER SYSTEM COMPONENT REPLACEMENT/KEY ADDITION AND CLEARING [KEYLESS ENTRY SYSTEM].)

Note

•  Two or more keys must be registered to start the engine.

•  Using the registered key, turn the ignition switch to the ON position.

•  Is the DTC displayed again?
