M range position indicator light does not illuminate in M range and/or in D range with direct mode/M range position indicator light illuminates in D range while not in direct mode

DESCRIPTION

•  M range position indicator light in instrument cluster does not illuminate in M range and/or in D range in direct mode when ignition switch is in ON position.

•  M range position indicator light illuminates in D range while not in direct mode when ignition switch is in ON position.

POSSIBLE CAUSE

•  M range switch malfunction

•  Steering shift switch malfunction

•  Open or short circuit in wiring harness between manual switch (built-in selector lever) and TCM

•  Open or short circuit in wiring harness between steering shift switch and TCM

Diagnostic procedure

STEP	INSPECTION		ACTION
1	• Access TCM PID MNL SW using the M-MDS. (See PID/DATA MONITOR INSPECTION [SJ6A-EL].) • Monitor the MLN SW PID with move the selector lever to all position and range. • Does the MNL SW PID indicate properly?	Yes	Go to the next step.
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 B and TCM terminal 2G.
2	• Access TCM PIDs UP SW and DWN SW using the M-MDS. (See PID/DATA MONITOR INSPECTION [SJ6A-EL].) • Monitor the UP SW and DWN SW PIDs by pressing the steering shift switch while the selector lever is in the D range. • Are the UP SW and DWN SW PIDs indicated correctly?	Yes	Inspect the instrument cluster using the input/output test mode. (See INSTRUMENT CLUSTER INSPECTION.)
2		No	Inspect the steering shift switch. (See STEERING SHIFT SWITCH INSPECTION.) If the steering shift switch is normal, inspect and repair the following wiring harnesses: • Between steering shift switch terminal F and TCM terminal 2AF • Between steering shift switch terminal C and TCM terminal 2AB
3	• 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.
