NO.2 VEHICLE MOVES IN N POSITION
A6E568001030W06
Diagnostic procedure
1 Vehicle does not move in D, S, L ranges, or in R position
DESCRIPTION
•
Vehicle does not move when AP depressed.
POSSIBLE
CAUSE
•
If the vehicle does not move in D, S, L ranges or R position, basically, the malfunction is in the ATX.
(Vehicle will move even with a malfunction in the PCM.) Since a malfunction is in the sensor circuit or
output circuit is the cause of the malfunction in the ATX, inspect the sensors, output circuit, and the
related harnesses.
1. Clutch slipped, worn (D, S, L ranges-Forward clutch, R position-Reverse clutch, Low and reverse
brake)
•
Line pressure low
•
Shift solenoid D malfunction
•
Shift solenoid E malfunction
•
Shift solenoid A malfunction
•
Shift solenoid B malfunction
•
Pressure control solenoid malfunction
•
Body GND malfunction
•
Control valve body malfunction
2. Selector lever malfunction
3. Parking mechanism not properly operation
4. Torque converter malfunction
Note
•
Before following troubleshooting steps, make sure that Automatic Transaxle On-Board Diagnostic
and Automatic Transaxle Basic Inspection are conducted.
STEP INSPECTION ACTION
1 When vehicle is stopped on a flat, level road and
engine is off, does vehicle move when pushed?
(in D, S ranges or N, R positions and brake is
released) Yes Go to next step.
No Check for parking mechanism. (See ATX workshop manual
(FN4A-EL) [1623-10-98E].) (See ATX workshop manual
supplement (FN4A-EL) [1746-1*-02C].)
2 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.
3 Check LPS PID value using WDS or equivalent.
Is LPS PID value okay?
(See
F–45 PCM INSPECTION .)
Yes Overhaul control valve body and repair or replace any
defective parts. If problem remains, overhaul transaxle and
repair or replace any defective parts. (See ATX workshop
manual (FN4A-EL) [1623-10-98E].) (See ATX workshop
manual supplement (FN4A-EL) [1746-1*-02C].)
No Repair or replace any defective parts.
2 Vehicle moves in N position
DESCRIPTION
•
Vehicle creeps in N position.
•
Vehicle creeps if brake pedal is not depressed in N position.
POSSIBLE
CAUSE
•
If the vehicle moves in N position, basically, the malfunction is in the ATX. Since a malfunction in the
sensor circuit or output circuit is the cause of the malfunction in the ATX, inspect the sensors, output
circuit, and the related harnesses.
1. Clutch burned (Forward clutch)
•
Control valve body malfunction
2. Selector lever position disparity (Although the selector indicator shows N position, hydraulic circuit
shows D range or R position)
Note
•
Before following troubleshooting steps, make sure that Automatic Transaxle On-Board Diagnostic
and Automatic Transaxle Basic Inspection are conducted.
STEP INSPECTION ACTION
1 Does vehicle creep when selector lever is moved
slightly in N position? Yes Go to next step.
No Adjust selector lever. (See K–46–3 SELECTOR CABLE
ADJUSTMENT .)
