id0503a1801000

5 | No creep at all
DESCRIPTION | • Vehicle does not move in D, S, L ranges, or R position when idling on flat paved road.
POSSIBLE CAUSE | • Either transaxle is stuck in 3GR or 4GR position, or clutch circuit slippage due to a stuck 3-4 clutch is stuck. 1. Clutch burned • 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 • Poor connection of connector • The electronic parts of output and input system have malfunction 3. The engine torque is not start • 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 | • Does vehicle creep in any range/position? | Yes | Go to next step.
No | Inspect or adjust selector lever. (See SELECTOR LEVER REMOVAL/INSTALLATION.)
2 | • Check the value at the following PID using the WDS or equivalent. (See PCM INSPECTION [WITHOUT WU-TWC].) (See PCM INSPECTION [WITH WU-TWC].) - TP • Is PID value normal? | Yes | Go to next step.
No | Repair or replace any defective parts.
3 | • Disconnect PCM. • Is resistance between ground terminal at PCM connector and body ground less than 5.0 ohms? | Yes | Go to next step.
No | Repair open ground circuit.
4 | • Check LPS PID value. (See PCM INSPECTION [WITHOUT WU-TWC].) (See PCM INSPECTION [WITH WU-TWC].) • Is LPS PID value normal? | Yes | Overhaul control valve body and repair or replace any defective parts. (See ATX workshop manual (FN4A-EL) [1623-10-98E].) If problem remains, overhaul transaxle and repair or replace any defective parts. (See ATX workshop manual (FN4A-EL) [1623-10-98E].)
No | Repair or replace any defective parts.
5 | • Verify test results. - If normal, return to diagnostic index to service any additional symptoms. - If malfunction remains, inspect related Service Information and perform repair or diagnosis. • If vehicle repaired, troubleshooting completed. • If vehicle not repaired or additional diagnostic information not available, replace PCM.
