Vehicle does not move in D, M ranges, or in R position

DESCRIPTION

•  Vehicle does not move when the accelerator pedal is depressed.

POSSIBLE CAUSE

•  If the vehicle does not move in D, M ranges or R position, basically, the malfunction is in the ATX. (Vehicle will move even with a malfunction in the TCM.) Since a malfunction is in the sensor circuit or output circuit is the cause of the malfunction in the ATX, inspect the sensors, output circuit, and the related wiring harnesses.

1.  Clutch slippage, worn (D, M ranges-Forward clutch, R position-Reverse clutch, Low and reverse brake, Reduction brake)

•  Line pressure low

•  Shift solenoid D malfunction

•  Shift solenoid A malfunction

•  Shift solenoid B malfunction

•  Pressure control solenoid A malfunction

•  Pressure control solenoid B malfunction

•  Body GND malfunction

•  Control valve body malfunction

2.  Selector lever malfunction

3.  Improper operation of parking mechanism

4.  Torque converter malfunction

Note

•  Before following the troubleshooting steps, make sure that the Automatic Transaxle On-Board Diagnostic and Automatic Transaxle Basic Inspection are conducted.

Diagnostic procedure

STEP	INSPECTION		ACTION
1	When the vehicle is stopped on a flat, level road and the engine is off, does the vehicle move when pushed? (in D range or N, R positions with the brake pedal released)	Yes	Go to the next step.
1		No	Inspect for parking mechanism. (See ATX workshop manual [FS5A-EL].)
2	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.
2		No	Repair open ground circuit.
3	Inspect the value at the following TCM PID using the M-MDS. (See PID/DATA MONITOR INSPECTION [FS5A-EL].) • LPS Is the LPS PID value normal?	Yes	Overhaul the control valve body and repair or replace any malfunctioning parts. (See ATX workshop manual [FS5A-EL].) If any problem remains, overhaul the transaxle and repair or replace any malfunctioning parts. (See ATX workshop manual [FS5A-EL].)
3		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 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.
