NO.5 NO CREEP AT ALL [5R55S]

id0503c1801000

5

No creep at all

DESCRIPTION

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

POSSIBLE CAUSE

•  Either transmission is stuck in 4GR or clutch slippage due to a stuck 3–4 clutch.

1.  Clutch is burned

•  Line pressure low

•  Shift solenoid D malfunction

•  Shift solenoid A malfunction

•  Shift solenoid B malfunction

•  Shift solenoid C malfunction

•  Pressure control solenoid A malfunction

•  Body ground malfunction

•  Control valve body malfunction

2.  Transmission fixed in 4GR (Operation of fail-safe function)

•  Short or open circuit in wiring harness

•  Poor connection of connector

•  Electronic parts of output and input system have malfunction

3.  No engine torque

•  Low engine RPM

•  Torque converter malfunction

Note

•  Before the following the troubleshooting steps, make sure that the Automatic Transmission On-Board Diagnostic and Automatic Transmission Basic Inspections are conducted.
(See BASIC INSPECTION [5R55S].)

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 INSPECTION.) (See SELECTOR CABLE ADJUSTMENT.)
2	Check the value at the following PCM PIDs using the IDS/PDS. (See PCM INSPECTION (Thailand, General (L.H.D. R.H.D.) specs.) [WL-C, WE-C].) • APP1 • APP2 • RPM Are PID values normal?	Yes	Go to the next step.
2		No	Repair or replace any malfunctioning parts.
3	Disconnect the TCM connector. Is the resistance between TCM ground terminal CO and body ground, and between TCM ground terminal CL and body ground less than 5.0 ohms?	Yes	Go to the next step.
3		No	Repair the open ground circuit.
4	Inspect the pressure control solenoid A. (See SOLENOID VALVE INSPECTION [5R55S].) Is it normal?	Yes	Clean and inspect main control, if parts are damaged replace main control. If the problem remains, overhaul the transmission and repair or replace any malfunctioning parts.
4		No	Repair or replace any malfunctioning parts.
5	• Verify 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 repaired, the troubleshooting is completed. • If the vehicle the not repaired or additional diagnostic information is not available, replace the TCM.
