Transaxle Drive Cycle Test

Transaxle Drive Cycle Test

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

After carrying out the Quick Test, use this Transaxle Drive Cycle Test for checking continuous codes:

NOTE: The Transaxle Drive Cycle Test must be followed exactly. Malfunctions must occur 4 times consecutively for shift error DTC code to be set, and five times consecutively for continuous torque converter clutch code to set.

NOTE: When carrying out the Transaxle Drive Cycle Test, refer to the solenoid operation chart for correct solenoid operation.

1. Record and then erase Quick Test codes.
2. Warm engine to normal operating temperature.
3. Make sure transmission fluid level is correct.
4. With transaxle in OVERDRIVE, moderately accelerate from stop to 80 km/h (50 mph). This allows the transaxle to shift into 4th gear. Hold speed and throttle opening steady for minimum of 15 seconds.
5. With transaxle in 4th gear and maintaining steady speed and throttle opening, lightly apply and release brake (to operate stoplamps). Then hold speed and throttle steady for additional 5 seconds minimum.
6. Brake to a stop and remain stopped for minimum of 20 seconds.
7. Repeat Steps 4 through 6 at least 5 times.
8. Carry out Quick Test and record continuous codes.
^ If DTCs are present, refer to Diagnostic Trouble Code (DTC) Charts. Service all non-transaxle DTCs first as they can directly affect the operation of the transaxle. Repeat the Quick Test and Road Test to verify the correction. Erase DTCs, carry out drive cycle, and repeat the Quick Test after completing service on the DTCs. Road Testing Vehicle
^ If the continuous test passes (system pass) and a concern is still present, refer to Diagnosis By Symptom and check for TSBs for diagnostic concern. Diagnosis By Symptom
