Memory Function
•The memory function stores failure information detected in the failure detection function. Once failure
information is stored, the memory will not be cleared even when the ignition switch is turned off (LOCK
position) or the malfunction is repaired.
•The stored memory (failure information) can be cleared by using the WDS or disconnecting the negative
battery cable.
Failure Indication Function
•The failure indication function illuminates the AT warning lights when the failure detection function determines
there is a malfunction.
DTC Table
X : Available
CCM:Continuous monitor
Fail-safe Function
•In the fail-safe function, minimum vehicle drivability is obtained by changing the signals that are determined as
malfunctions by the failure detection function to the preset values, and limiting the TCM control.

STEP INSPECTION ACTION
1•Does vehicle creep when selector lever
moved slightly in N position?Yes•Overhaul control valve body and repair or replace any
defective parts.
(See ATX Workshop Manual.)
—If problem remains, replace or overhaul transaxle and
repair or replace any defective parts.
(See K2–99 AUTOMATIC TRANSAXLE AND
TRANSFER REMOVAL/INSTALLATION.)
(See ATX Workshop Manual.)
No Inspect and adjust selector lever.
(See K2–117 SELECTOR LEVER INSPECTION.)
(See K2–118 SELECTOR CABLE ADJUSTMENT.)
2•Verify test results.
—If okay, return to diagnostic index to service any additional symptoms.
—If malfunction remains, inspect related Service Informations and perform repair or diagnosis.
—If vehicle repaired, troubleshooting completed.
—If vehicle not repaired or additional diagnostic information not available, replace TCM.
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 locked when P disengaged, vehicle does not move in D range, and R position when accelerator
pedal depressed, and engine remains in stall condition.
POSSIBLE
CAUSE•Malfunction of parking mechanism (May have effect on noise or shock from transaxle)
•Improper adjustment of selector lever
•If vehicle moves in N position, perform symptom troubleshooting No.2 “Vehicle moves in N position”
Note
•Before following troubleshooting steps, make sure that Automatic Transaxle On-Board Diagnostic
and Automatic Transaxle Basic Inspection are conducted.
4 Excessive creep
DESCRIPTION•Vehicle accelerates in D range, and R position without depressing accelerator pedal.
POSSIBLE
CAUSE•Engine idle speed high (transaxle system is not cause of problem)
•Go to symptom troubleshooting No.9 “Fast idle/runs on”
(See Section F.)
Note
•Before following troubleshooting steps, make sure that Automatic Transaxle On-Board Diagnostic
and Automatic Transaxle Basic Inspection are conducted.
5 No creep at all
DESCRIPTION•Vehicle does not move in D range, or R position when idling on flat paved road.
POSSIBLE
CAUSE•Either engine output low or there is clutch circuit slippage.
—Clutch burned
•Line pressure low
•Malfunction of shift solenoid A, B, or C
•Malfunction of body ground
•Malfunction of control valve body
—Transaxle fixed in 4GR (Operation of fail-safe function)
•Short or open circuit in wiring
•Poor connection of connector
•Electronic parts of output and input system malfunctioning
—Engine torque is not start
•Malfunction of torque converter
Note
•Before following troubleshooting steps, make sure that Automatic Transaxle On-Board Diagnostic
