NO. 6 LOW MAXIMUM SPEED AND POOR ACCELERATION (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 ENGINE CONTROL SYSTEM FOR MALFUNCTION Go to No. 12 "LACK/LOSS OF POWER-ACCELERATION/CRUISE". (See NO. 12 LACK/LOSS OF POWER-ACCELERATION/CRUISE .) Is the CIS system normal?	Yes	Go to the next step.
2		No	Repair or replace any malfunctioning parts.
3	DETERMINE IF MALFUNCTION CAUSE IS INPUT/OUTPUT SIGNAL OR TRANSAXLE (INCLUDING CONTROL VALVE BODY) Disconnect the solenoid connector. Does the vehicle operate as follows? D position: 3GR (fixed) R position: Reverse	Yes	Go to the next step.
3		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 )
4	INSPECT INPUT SIGNAL PARTS FOR MALFUNCTION Drive the vehicle in D position. Does the vehicle start from stop in first gear?	Yes	Go to the next step.
4		No	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 TCM PIDs: THOP OSS TSS TR Repair or replace any malfunctioning parts.
5	INSPECT IF OUTPUT SIGNAL MALFUNCTION CAUSED BY MALFUNCTIONING INPUT SIGNAL Inspect the value at the following TCM PIDs using the M-MDS. (See ON-BOARD DIAGNOSTIC SYSTEM PID/DATA MONITOR INSPECTION .) SSA/SS1 SSB/SS2 SSC/SS3 SSF_SS6 Are the PID values normal?	Yes	Go to the next step.
5		No	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 TCM PIDs: THOP OSS TSS Repair or replace any malfunctioning parts.
6	INSPECT FOR TRANSAXLE INTERNAL MALFUNCTION Perform the stall test. (See MECHANICAL SYSTEM TEST .) Is stall speed normal?	Yes	Reverify symptoms of malfunction.
6		No	Overhaul the transaxle and repair or replace any malfunctioning parts. (See AUTOMATIC TRANSAXLE - [FS5A-EL] -- MAZDA6 )
7	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.
