TROUBLESHOOTING
! N0.2 VEHICLE MOVES IN N POSITION
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 light shows N position, the hydraulic circuit
shows D range, R position)
Diagnostic procedure
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 K2-56 SELECTOR LEVER
REMOVAL/INSTALLATION.)
2 Check the value at the following PID using the
NGS tester.
(See F1-25 PCM INSPECTION.)
• TP V
Is PID value okay?
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 fi?
Yes Go to next step.
No Repair open ground circuit.
Reconnect PCM.
4 Check LINE PID value.
Is LINE PID value okay? 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.
N0.3 VEHICLE MOVES IN P POSITION, OR PARKING GEAR DOES NOT DISENGAGE WHEN P IS
DISENGAGED
3 Vehicle moves in P position, or parking gear does not disengage when P Is disengaged
DESCRIPTION
• Vehicle rolls when on a downward slope and tires do not lock in P position.
• Tires are locked when P is disengaged, vehicle does not move in D, S, L ranges, and R position when AP
is depressed, and engine remains in stall condition.
POSSIBLE
CAUSE
1. Parking mechanism malfunction (May have effect on noise or shock from transaxle)
2. Improper adjustment of selector lever
3. If vehicle moves in N position, perform No.2 “Vehicle moves in N position”
N0.4 EXCESSIVE CREEP
4
Excessive creep
DESCRIPTION • Vehicle accelerates in D, S, L ranges, and R position without depressing accelerator pedal.
POSSIBLE
CAUSE
1. Engine idle speed high (transaxle system is not cause of problem)
2. Go to No.8 “Fast idle/runs on” (See F1-120 No.8 FAST IDLE/RUNS ON.)
