id050307808900

28 | Gear position indicator light illuminate in P, R and N position
DESCRIPTION | • Gear position indicator light in instrument cluster illuminates in P, R and N position with the ignition switch at ON.
POSSIBLE CAUSE | • M range switch (built-in selector lever), TR switch, instrument cluster, or related wiring harness malfunction Note • Before following the troubleshooting steps, make sure that the Automatic Transaxle ON-Board Diagnostic and Automatic Transaxle Basic Inspection are conducted. (See BASIC INSPECTION [SJ6A-EL].)

Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | • With the ignition switch at ON position. • When selector lever is moved, does selector illumination indicate synchronized position to lever location? | Yes | Go to the next step.
No | Inspect the TR switch. (See TRANSMISSION RANGE (TR) SWITCH INSPECTION [SJ6A-EL].)
2 | • Inspect the TR PID value using the M-MDS. (See PID/DATA MONITOR INSPECTION [SJ6A-EL].) • Is the TR PID value normal? | Yes | Go to Step 7.
No | Go to the next step.
3 | • Adjust the TR switch. (See TRANSMISSION RANGE (TR) SWITCH ADJUSTMENT [SJ6A-EL].) • Reinspect the TR PID value. • Is the TR PID value normal? | Yes | Symptom troubleshooting is completed. (TR switch is mis-adjustment.)
No | Go to the next step.
4 | • Inspect the TR switch. (See TRANSMISSION RANGE (TR) SWITCH INSPECTION [SJ6A-EL].) • Is the TR switch normal? | Yes | Inspect and repair the wiring harness between TCM terminal 2N/2O/2M/2K and TR switch.
No | Replace the TR switch. (See TRANSMISSION RANGE (TR) SWITCH REMOVAL/INSTALLATION [SJ6A-EL].)
5 | • Inspect the MNL SW PID value using the M-MDS. (See PID/DATA MONITOR INSPECTION [SJ6A-EL].) • Is the MNL SW PID value normal? | Yes | Go to Step 7.
No | Go to the next step.
6 | • Inspect the M range switch. (See SELECTOR LEVER COMPONENT INSPECTION.) • Is the M range switch normal? | Yes | Inspect and repair the wiring harness between TCM terminal 2G and selector lever component terminal B.
No | Replace the selector lever component. (See SELECTOR LEVER REMOVAL/INSTALLATION.)
7 | • Inspect the instrument cluster. (See INSTRUMENT CLUSTER INSPECTION.) • Is the instrument cluster normal? | Yes | Go to the next step.
No | Replace the instrument cluster. (See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.)
8 | • Verify test results. ― If normal, return to the diagnostic index to service any additional symptoms. ― If malfunction remains, inspect the related Service Information and perform repair or diagnosis. • If the vehicle is repaired, troubleshooting completed. • If the vehicle is not repaired or additional diagnostic information is not available, replace the TCM. (See TCM REMOVAL/INSTALLATION [SJ6A-EL].)
