Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | With the ignition switch at the ON position, does the gear position indicator light indication correspond to the selector lever position? | Yes | Go to the next step.
No | Go to No.29 "GEAR POSITION INDICATOR LIGHT DOES NOT ILLUMINATE IN M RANGE", or No.30 "GEAR POSITION INDICATOR LIGHT ILLUMINATES IN D RANGE OR P, N, R POSITIONS".
2 | Disconnect the TCM connector. Is the resistance between ground terminal 2M or 2Q at the TCM connector and body ground 5.0 ohms or less? | Yes | Go to the next step.
No | Repair open ground circuit.
3 | Inspect shift solenoid F and pressure control solenoid circuit. (See SOLENOID VALVE INSPECTION.) Are they normal? | Yes | Overhaul the control valve body and repair or replace any malfunctioning parts. (See AT Workshop Manual.) If the problem remains, overhaul the transmission and repair or replace any malfunctioning parts. (See AT Workshop Manual)
No | Repair or replace any malfunctioning parts.
4 | 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 completed. – If the vehicle is not repaired or additional diagnostic information is not available, replace the TCM.
