Diagnostic Procedure

STEP

INSPECTION

ACTION

1

VERIFY DTC

•  Are either U1900 or U0073, or both, displayed, by either the instrument cluster or the PCM, or both?

Yes

Perform troubleshooting according to the corresponding DTC inspection.

(See PROCEDURES FOR DETERMINING THE LOCATION OF A MALFUNCTION[MULTIPLEX COMMUNICATION SYSTEM].)

No

Replace the instrument cluster and perform the resetting procedure for the immobilizer system when replacing the instrument cluster.

(See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.)

(See IMMOBILIZER SYSTEM COMPONENT REPLACEMENT/KEY ADDITION AND CLEARING[KEYLESS ENTRY SYSTEM].)

Go to the next step.

2

VERIFY DTC

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

•  Is the DTC displayed?

―  Security light: 16

―  M-MDS: U2510 or U1147/P1260

Yes

Replace the PCM and perform the resetting procedure for the immobilizer system when replacing the PCM.
