NO.5 NO CREEP AT ALL[FN4A-EL]

id0503a1801000

5

No creep at all

DESCRIPTION

•  Vehicle does not move in D, M ranges and R position when idling on a flat paved road.

POSSIBLE CAUSE

•  Either transaxle is stuck in 3GR or 4GR position, or there is clutch circuit slippage due to a stuck 3–4 clutch.

1.  Clutch burnt

•  Line pressure low

•  Shift solenoid D malfunction

•  Shift solenoid A malfunction

•  Shift solenoid B malfunction

•  Shift solenoid C malfunction

•  Pressure control solenoid malfunction

•  Body GND malfunction

•  Control valve body malfunction

2.  Transaxle fixed in 3GR (Operation of fail-safe function)

•  Short or open circuit in wiring harness

•  Poor connection of connector

•  Malfunction of electronic parts of output and input system

3.  There is no engine torque

•  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	Does the vehicle creep in any range/position?	Yes	Go to the next step.
1	Does the vehicle creep in any range/position?	No	Inspect or adjust the selector lever. (See SELECTOR LEVER COMPONENT REMOVAL/INSTALLATION.)
2	Inspect the value at the following PCM PID using the M-MDS. (See PCM INSPECTION[ZJ, ZY, Z6].) (See PCM INSPECTION[LF, L3].) • TP • APP1 • APP2 • TP1 Is the PID value normal?	Yes	Go to the next step.
2		No	Repair or replace any malfunctioning parts.
3	Disconnect the PCM connector. Is the resistance between the ground terminal at the PCM connector and the body ground less than 5.0 ohms?	Yes	Go to the next step.
3		No	Repair open ground circuit.
4	Inspect the LPS PID value. Is the LPS PID value normal? (See PCM INSPECTION[ZJ, ZY, Z6].) (See PCM INSPECTION[LF, L3].)	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 malfunctioning parts.
5	• 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 PCM.
