31	M range position indicator light does not illuminate in M range/M range position indicator light illuminates in D range
DESCRIPTION	• M range position indictor light in instrument cluster does not illuminate in M range or M range position indicator light illuminates in D range with the ignition switch is ON position.
POSSIBLE CAUSE	• M range switch malfunction • Open or short circuit in wiring harness between M range switch and TCM Note • Before following the troubleshooting steps, make sure that the Automatic Transaxle On-Board Diagnostic and Automatic Transaxle Basic Inspection are conducted.

Diagnostic procedure

STEP	INSPECTION		ACTION
1	• Access the TCM PID MNL SW using the M-MDS. (See ON-BOARD DIAGNOSTIC SYSTEM PID/DATA MONITOR INSPECTION [AW6A-EL, AW6AX-EL].) • Monitor the MNL SW PID with move the selector lever to all position and range. • Does the MNL SW PID indicate properly?	Yes	Turn the M range position indicator light on and off using the M-MDS simulation function. (See ACTIVE COMMAND MODES INSPECTION [INSTRUMENT CLUSTER].) • If the M range position indicator light dose not turn on and off according to the simulation command, replace the instrument cluster. • If the M range position indicator light turns on and off according to the simulation command, inspect and repair the wiring harness between the TCM and instrument cluster.
1		No	Inspect the M range switch. (See SELECTOR LEVER COMPONENT INSPECTION.) • If the M range switch is normal, inspect and repair wiring harness between manual switch terminal A and TCM terminal K.
2	• Verify test results. ― If normal, return to the diagnostic index to service any additional symptoms. ― If the malfunction remains, inspect the related Service 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.
