Monitors, Trips, Drive Cycles and Readiness Codes

DESCRIPTION
After performing the Quick Test, use the following Transmission Drive Cycle Test for checking transmission continuous codes:

NOTE:
- The Transmission Drive Cycle Test must be followed exactly. Abnormal operation has to occur four times consecutively for codes P0781, P0782, and P0783 to be set, and five times consecutively for continuous codes P 1728, P 1744, P0741, P0743.
- When performing the Transmission Drive Cycle Test, refer to Shift Solenoid Operation Chart for proper solenoid operation.

PROCEDURE
1. Record and then erase Quick Test DTCs.
2. Warm engine to normal operating temperature.
3. Make sure transmission fluid level is correct.
4. With transmission In OVERDRIVE, moderately accelerate from stop to 80 Km/h (50 mph). This allows the transmission to shift into fourth gear. Hold speed and throttle open steady for a minimum of 15 seconds.
5. With transmission in OVERDRIVE, press TCS (TCIL should illuminate) and moderately accelerate from stop to 64 Km/h (40 mph). This allows transmission to shift into third gear. Hold speed and throttle open steady for a minimum of 15 seconds (30 seconds above 1220 meters (4000 ft)).
6. Press TCS (TCIL should turn off) and accelerate from 64 Km/h (40 mph) to 80 Km/h (50 mph). This allows transmission to shift into fourth gear. Hold speed and throttle position steady for a minimum of 15 seconds.
7. With transmission in fourth gear and maintaining steady speed and throttle opening, lightly apply and release brake (to operate stoplamps). Then hold speed and throttle steady for an additional five seconds minimum.
8. Brake to a stop and remain stopped for a minimum of 20 seconds.
9. Repeat Steps 4 through 8 at least five times.
10. Perform Quick Test and record continuous DTCs.
