Transaxle Drive Cycle Test: Notes

SPECIAL TOOLS

Vehicle Communication Module (VCM) and Integrated Diagnostic System (IDS) software with appropriate hardware, or equivalent scan tool

NOTE: Always drive the vehicle in a safe manner according to driving conditions and obey all traffic laws.

After carrying out the self-test, use the following Transmission Drive Cycle Test for checking continuous codes:

NOTE: The Transmission Drive Cycle Test must be followed exactly. Malfunctions must occur 4 times consecutively for the shift error DTC to be set. Torque converter failures must occur 5 times consecutively for a continuous DTC to be set.

NOTE: When carrying out the Transmission Drive Cycle Test, see the Solenoid Operation Chart for correct solenoid operation. Refer to PINPOINT TESTS - OSC EQUIPPED VEHICLE .

Record then clear self-test DTCs.
Warm engine to normal operating temperature.
Make sure transmission fluid level is correct.
With transmission in DRIVE, moderately accelerate from stop to 80 km/h (50 mph). This allows the transmission to shift into 6th gear. Hold speed and throttle opening steady for a minimum of 15 seconds.
With transmission in 6th gear and maintaining steady speed and throttle opening, lightly apply and release the brake to operate the stoplamps. Hold speed and throttle steady for additional 5 seconds minimum.
Brake to a stop and remain stopped for minimum of 20 seconds.
Repeat Steps 4 through 6 at least 5 times.
Carry out the self-test and record continuous codes.
- If DTCs are present, refer to DIAGNOSTIC TROUBLE CODE (DTC) CHARTS . Service all non-transmission DTCs first as they can directly affect the operation of the transmission. Repeat the self-test and road test the vehicle to verify the correction. Clear the DTCs, carry out drive cycle and repeat the self-test after completing service on the DTCs.
- If the self-test passes and a concern is still present, refer to DIAGNOSIS BY SYMPTOM . Check TSBs for diagnostic concern.
