Vehicle moves in N position

DESCRIPTION

•  Vehicle creeps in N position.

•  Vehicle creeps if brake pedal is not depressed in N position.

POSSIBLE CAUSE

•  If the vehicle moves in N position, basically, the malfunction is in the ATX. Since a malfunction 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 burned (Forward clutch)

•  Control valve body malfunction

2.  Selector lever position disparity (Although the selector indicator shows N position, hydraulic circuit shows D range or R position)

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	Does vehicle creep when selector lever is moved slightly in N position?	Yes	Go to next step.
1		No	Adjust selector cable. (See SELECTOR CABLE ADJUSTMENT.)
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. Reconnect PCM connector.
3	Check LPS PID value using the M-MDS. Is LPS PID value okay? (See PCM INSPECTION [MZR 1.3, MZR 1.5].)	Yes	Overhaul control valve body and repair or replace any defective parts. If problem remains, overhaul transaxle and repair or replace any defective parts.
3		No	Repair or replace any defective parts.
4	• 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.
