NO.5 NO CREEP AT ALL [GF4AX-EL]


5	No creep at all
DESCRIPTION	• Vehicle does not move in D, 2, 1 ranges, or R position when idling on flat level 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 A, B, or C malfunction • Body GND malfunction • Control valve body malfunction 2. Transaxle fixed in 3GR or 4GR (Operation of fail-safe function) • Short or open circuit in wiring harness • Poor connector connection • 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.


STEP	INSPECTION		ACTION
1	Does the vehicle creep in P and/or N position?	Yes	Inspect or adjust the selector lever. (See SELECTOR LEVER INSPECTION.) (See SELECTOR CABLE ADJUSTMENT.)
1	Does the vehicle creep in P and/or N position?	No	Go to the next step.
2	Stop engine and turn the ignition switch to the ON position. Connect the WDS or equivalent to DLC-2. Simulate LPS PID for 50 %. Is operating sound of the pressure control solenoid heard?	Yes	Go to the next step.
2		No	Inspect connection of the pressure control solenoid terminal on the ATX for bend, damage, corrosion or looseness. Inspect for stuck pressure control solenoid. (See Operating Inspection (On-vehicle Inspection).) If the pressure control solenoid is normal, inspect for open or short circuit between the PCM terminal 91 and the pressure control solenoid terminal G.
3	Remove the torque converter. Inspect the torque converter. (See ATX Workshop Manual (GF4AX-EL)) Is the torque converter normal?	Yes	Overhaul the control valve body and repair or replace any malfunctioning parts. (See ATX Workshop Manual (GF4AX-EL)) If any problem remains, replace or overhaul the transaxle and repair or replace any malfunctioning parts. (See AUTOMATIC TRANSAXLE AND TRANSFER REMOVAL/INSTALLATION [GF4AX-EL].)
3		No	Replace the torque converter.
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 PCM.
