Monitors, Trips, Drive Cycles and Readiness Codes

NOTE: The transaxle drive cycle test must be followed exactly. Faults have to occur consecutively for codes P0731, P0732, P0733, and P0734 to be set, and five times consecutively for continuous codes P0741 and P1741.

NOTE: When carrying out the Transaxle Dive 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 D position, press Transmission Control Switch (TCS) (LED lamp should illuminate) and moderately accelerate from a stop to 64 km/h (40 mph). This allows the transaxle to shift into third gear. Hold the speed and throttle opening steady for a minimum of 15 seconds (30 seconds above an altitude of 4000 feet above sea level).
5. Press TCS (LED lamp should turn off) and accelerate from 64 km/h (40 mph) to 80 km/h (50 mph). This allows the transaxle to shift into fourth gear. Hold the speed and throttle opening steady for a minimum of 15 seconds.
6. With the transaxle in fourth Year and maintaining steady speed and throttle opening, lightly apply brake pedal (to operate stoplamps). Then hold the speed and throttle steady for an additional five seconds (minimum).
7. Brake to a stop and remain stopped for a minimum of 20 seconds.
8. Repeat Steps 4 through 6 at least five times.
9. Carry out Quick Test and record continuous codes.

NOTE: The vehicle wiring harness, Powertrain Control Module (PCM) and non-transaxle sensors may affect transaxle operations. Repair these concerns first.

After the on-board diagnostic procedures are completed, repair all DTCs.
Begin with non-transaxle related DTCs, then repair any transaxle-related DTCs. Refer to the On-Board Diagnostic Trouble Code Description Chart for information on Condition and Symptoms. This chart will be helpful to aid in diagnosing internal transaxle concerns and external non-transaxle inputs. The pinpoint tests are used in diagnosing electrical concerns of the CD4E transaxle. Make sure that the vehicle wiring harness and the PCM are diagnosed as well. The diagnostic routine hydraulic/mechanical charts will help in diagnosing internal transaxle concerns and external non-transaxle inputs.
