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 component) malfunction
•  Steering shift switch or related circuit malfunction (with steering shift switch)
•  Open or short circuit in wiring harness between manual switch (built-in selector lever component) and TCM
•  Open or short circuit in wiring harness between steering shift switch and TCM

Diagnostic procedure

STEP

INSPECTION

ACTION
1
Inspect the MNL SW PID value using the M-MDS.
(See ON-BOARD DIAGNOSTIC SYSTEM PID/DATA MONITOR INSPECTION [FS5A-EL].)
Monitor the MLN SW PID with move the selector lever to all position and range.
Is the PID value normal?
Yes
With steering shift switch:
•  Go to the next step.
Without steering shift switch:
•  Verify that the M range position indicator light using M-MDS simulation function WL+IL.
•  Replace the instrument cluster if necessary.
No
Inspect the M range switch.
(See M RANGE SWITCH INSPECTION [FS5A-EL].)
If the M range switch is normal:
•  Inspect the wiring harness between selector lever component terminal A and TCM terminal K.
•  Repair or replace the any malfunctioning parts according to the inspection results.
2
Inspect the UP SW and DWN SW PID values using the M-MDS.
(See ON-BOARD DIAGNOSTIC SYSTEM PID/DATA MONITOR INSPECTION [FS5A-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 PID values normal?
Yes
Verify the M range position indicator light using M-MDS simulation function WL+IL.
(See ACTIVE COMMAND MODES INSPECTION [INSTRUMENT CLUSTER].)
Replace the instrument cluster if necessary.
(See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.)
No
Inspect the steering shift switch.
(See STEERING SHIFT SWITCH INSPECTION [FS5A-EL].)
If the steering shift switch is normal:
•  Inspect the following wiring harnesses:
―  Between steering shift switch (right side) terminal A and TCM terminal T
―  Between steering shift switch (left side) terminal A and TCM terminal X
•  Repair or replace the any malfunctioning parts according to the inspection results.
3
•  Verify the 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. (See TCM REMOVAL/INSTALLATION [FS5A-EL].)
