NO. 12 TORQUE CONVERTER CLUTCH (TCC) NON-OPERATION (FS5A-EL) DIAGNOSTIC PROCEDURE

STEP	INSPECTION		ACTION
1	INSPECT SELECTOR LEVER POSITION SIGNAL FOR MALFUNCTION With the ignition at the ON, does the gear position indicator light indication correspond to the selector lever position?	Yes	Go to the next step.
1		No	Go to NO. 27 GEAR POSITION INDICATOR LIGHT DOES NOT ILLUMINATE IN M POSITION
2	INSPECT INPUT SIGNAL FOR MALFUNCTION Inspect the value at the following PCM and TCM PIDs using the M-MDS. (See PCM INSPECTION .) (See ON-BOARD DIAGNOSTIC SYSTEM PID/DATA MONITOR INSPECTION .) PCM PID: APP RPM TCM PIDs: THOP OSS TSS Are the PID values normal?	Yes	Go to the next step.
2		No	Repair or replace any malfunctioning parts.
3	INSPECT TCM FOR POOR GND Disconnect the TCM connector. Is the resistance between the ground terminal at the TCM connector and the body ground less than 5.0 ohms?	Yes	Go to the next step.
3		No	Repair the open ground circuit.
4	INSPECT SHIFT SOLENOID A OR E CONTROL SIGNAL CIRCUIT FOR MALFUNCTION Inspect the resistance between shift solenoid A and E control circuit at the TCM connector and control valve body connector. Inspect resistance between shift solenoid A and E circuit at the TCM connector and control valve body connector. Are the resistances less than 5.0 ohms?	Yes	Go to the next step.
4		No	Repair the shift solenoid A or E control circuit. Reconnect the TCM connector.
5	VERIFY IF MALFUNCTION CAUSE IS SHIFT SOLENOID A OR E OR TCM CONTROL Inspect the shift solenoid A and E. (See SOLENOID VALVE INSPECTION .) Are the shift solenoids operating properly?	Yes	Replace the TCM.
5		No	Overhaul the control valve body and repair or replace any malfunctioning parts. (See AUTOMATIC TRANSAXLE - [FS5A-EL] -- MAZDA6 ) If any problem remains, overhaul the transaxle and repair or replace any malfunctioning parts. (See AUTOMATIC TRANSAXLE - [FS5A-EL] -- MAZDA6 )
6	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 is completed. If the vehicle is not repaired or additional diagnostic information is not available, replace the TCM.
