Vehicle does not move in D, S, L ranges, or in R position

DESCRIPTION

•  Vehicle does not move when AP depressed.

POSSIBLE CAUSE

•  If the vehicle does not move in D, S, L ranges or R position, basically, the malfunction is in the ATX. (Vehicle will move even with a malfunction in the PCM.) 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 harnesses.

1.  Clutch slipped, worn (D, S, L ranges-Forward clutch, R position-Reverse clutch, Low and reverse brake)

•  Line pressure low

•  Shift solenoid D malfunction

•  Shift solenoid E malfunction

•  Shift solenoid A malfunction

•  Shift solenoid B malfunction

•  Pressure control solenoid malfunction

•  Body GND malfunction

•  Control valve body malfunction

2.  Selector lever malfunction

3.  Parking mechanism not properly operation

4.  Torque converter malfunction

Note

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

Diagnostic procedure

STEP	INSPECTION		ACTION
1	When vehicle is stopped on a flat, level road and engine is off, does vehicle move when pushed? (in D, S ranges or N, R positions and brake is released)	Yes	Go to next step.
1		No	Check for parking mechanism.
2	Disconnect PCM connector. Is resistance between GND terminal at PCM connector and body GND less than 5.0 ohms?	Yes	Go to next step.
2		No	Repair open GND circuit.
3	Check LPS PID value using the M-MDS. Is LPS PID value okay? (See PCM INSPECTION [MZR 1.3, MZR 1.5].)	Yes	Go to the next step.
3		No	Repair or replace any defective parts.
4	Perform the stall test. (See MECHANICAL SYSTEM TEST [FN4A-EL].) Is the stall speed normal?	Yes	Overhaul the control valve body and repair or replace any malfunctioning parts. (See ATX workshop manual (FN4A-EL).) If any problem remains, overhaul the transaxle and repair or replace any malfunctioning parts. (See ATX workshop manual (FN4A-EL).)
4		No	Repair or replace any defective parts.
5	• Verify test results. ― If okay, return to diagnostic index to service any additional symptoms. ― If malfunction remains, inspect related Service informations and perform repair or diagnosis. • If vehicle not repaired, trouble shooting completed. • If vehicle not repaired or additional diagnostic information not available, replace PCM.
