31 | 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 (built-in selector lever) malfunction • Steering shift switch malfunction • Open or short circuit in wiring harness between M range 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 the 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.
No | Inspect the M range switch. (See SELECTOR LEVER COMPONENT INSPECTION.) If the M range switch has a malfunction: • Replace the selector lever component. (See SELECTOR LEVER REMOVAL/INSTALLATION.) If the M range switch is normal: • Inspect for continuity between manual switch terminal B and TCM terminal 2G. • Repair or replace the suspected wiring harness.
2 | • Access the 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.) Replace the instrument cluster, if necessary. (See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.)
No | Inspect the steering shift switch. (See STEERING SHIFT SWITCH INSPECTION.) If the steering shift switch has a malfunction: • Replace the steering shift switch. (See STEERING SHIFT SWITCH REMOVAL/INSTALLATION.) If the steering shift switch is normal: • Inspect for continuity between the following terminals: ― Steering shift switch terminal F and TCM terminal 2AF. ― Steering shift switch terminal C and TCM terminal 2AB. • Repair or replace the suspected wiring harness.
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. (See TCM REMOVAL/INSTALLATION [SJ6A-EL].)
