Monitors, Trips, Drive Cycles and Readiness Codes

After performing the Quick Tests, use the Transmission Drive Cycle Test for checking transmission continuous codes.
1. Record and then erase Quick Test Diagnostic Trouble Codes (DTCs).

NOTE: The Transmission Drive Cycle Test must be followed exactly. A malfunction must occur four times consecutively for DTCs P0781, P0782, P0783, P1731, P1732, P1733 to be set, and five times consecutively for continuous DTC P0741 to be set.

2. Warm the engine to normal operating temperature.
3. Make sure the Automatic Transmission Fluid (ATF) level is correct.
4. With the transmission in (OD), 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 (30 seconds above 4,000 feet altitude).
5. With the transmission in D, moderately accelerate from stop to 64 km/h (40 mph). This allows the transmission to shift into third gear. Hold speed and throttle open steady for a minimum of 15 seconds (30 seconds above 4000 feet altitude).
6. Move the gearshift lever from D to (OD) and accelerate from 64 km/h (40 mph) to 80 km/h (50 mph). This allows the transmission to shift into fourth gear. Hold speed and throttle position steady for a minimum of 15 seconds.
7. With the transmission in fourth gear and maintaining steady speed and throttle opening, lightly apply and release the brake to operate the stoplamps. Hold speed and throttle steady for a minimum of five seconds.
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 the Transmission Drive Cycle Test and record continuous DTCs.
