STEP
INSPECTION
ACTION
1
Does the vehicle creep in any range/position?
Yes
Go to the next step.
No
Inspect or adjust the selector lever.
(See SELECTOR LEVER COMPONENT REMOVAL/INSTALLATION.)
2
Inspect the value at the following PCM PID using the WDS or equivalent.
(See PCM INSPECTION [Z6].)
• TP
Is the PID value normal?
Yes
Go to the next step.
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.
No
Repair open ground circuit.
4
Inspect the LPS PID value.
Is the LPS PID value normal?
(See PCM INSPECTION [Z6].)
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).)
