NO.27 GEAR POSITION INDICATOR LIGHT DOES NOT ILLUMINATE IN D OR M RANGE[FS5A-EL]

• M range switch, 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[FS5A-EL].)

STEP	INSPECTION	ACTION
1	With the ignition switch at ON, When selector lever is moved, does selector illumination indicate synchronized position to lever location?	Yes	Go to the next step.
No	Check value at the following. TCM terminal voltage: • 1U (TR switch) Repair or replace any defective parts.
2	Inspect the voltage at TCM terminal 1K (M range switch). (See TCM INSPECTION[FS5A-EL].) Is voltage normal?	Yes	Go to the next step.
No	Repair or replace any defective part.
3	Inspect the instrument cluster. (See INSTRUMENT CLUSTER INSPECTION.) Is instrument cluster normal?	Yes	Go to the next step.
No	Repair or replace any defective part.
4	Disconnect the TCM and instrument cluster connector. • Turn the ignition switch off. • Check continuity between the following circuits: ― TCM terminal 1B and body GND ― TCM terminal 1E and body GND ― Instrument cluster terminal 1I and body GND ― Instrument cluster terminal 1K and body GND • Is there continuity?	Yes	Repair or replace harness for short to GND, then go to the next step.
No	Go to the next step.
5	Disconnect the TCM and instrument cluster connector. • Turn the ignition switch off. • Check continuity between the following circuits: ― TCM terminal 1B and instrument cluster terminal 1I ― TCM terminal 1E and instrument cluster terminal 1K • Is there continuity?	Yes	Go to the next step.
No	Repair or replace harness for open circuit, then go to the next step.
6	• Verify the test results. ― If normal, return to the diagnostic index to service any additional symptoms. ― If the malfunction remains, inspect the related Service Bulletins and/or On-line Repair information and perform repair or diagnosis. • If the vehicle is repaired, troubleshooting is completed. • If the vehicle is not repaired or additional diagnostic information is not available, replace the TCM.

STEP

INSPECTION

ACTION

With the ignition switch at ON,

When selector lever is moved, does selector illumination indicate synchronized position to lever location?

Yes

Go to the next step.

Check value at the following.

TCM terminal voltage:

• 1U (TR switch)

Repair or replace any defective parts.

Inspect the voltage at TCM terminal 1K (M range switch).

(See TCM INSPECTION[FS5A-EL].)

Is voltage normal?

Yes

Go to the next step.

Repair or replace any defective part.

Inspect the instrument cluster.

(See INSTRUMENT CLUSTER INSPECTION.)

Is instrument cluster normal?

Yes

Go to the next step.

Repair or replace any defective part.

Disconnect the TCM and instrument cluster connector.

• Turn the ignition switch off.

• Check continuity between the following circuits:

― TCM terminal 1B and body GND

― TCM terminal 1E and body GND

― Instrument cluster terminal 1I and body GND

― Instrument cluster terminal 1K and body GND

• Is there continuity?

Yes

Repair or replace harness for short to GND, then go to the next step.

Go to the next step.

Disconnect the TCM and instrument cluster connector.

• Turn the ignition switch off.

• Check continuity between the following circuits:

― TCM terminal 1B and instrument cluster terminal 1I

― TCM terminal 1E and instrument cluster terminal 1K

• Is there continuity?

Yes

Go to the next step.

Repair or replace harness for open circuit, then go to the next step.

• Verify the test results.

― If normal, return to the diagnostic index to service any additional symptoms.

― If the malfunction remains, inspect the related Service Bulletins and/or On-line Repair information and perform repair or diagnosis.

• If the vehicle is repaired, troubleshooting is completed.

• If the vehicle is not repaired or additional diagnostic information is not available, replace the TCM.

27	Gear position indicator light does not illuminate in D or M range
DESCRIPTION	• Gear position indicator light in instrument cluster does not illuminate in D or M range with the ignition switch at ON.
POSSIBLE CAUSE	• M range switch, 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[FS5A-EL].)
