Drive Cycle Test

After performing the Quick Test, use the following Drive Cycle Test, for checking E40D continuous codes:

NOTE: THE FOLLOWING TEST MUST BE FOLLOWED EXACTLY. FAULTS HAVE TO OCCUR FOUR TIMES CONSECUTIVELY FOR CODES 49, 59, AND 69 TO BE SET, AND FIVE TIMES CONSECUTIVELY FOR CONTINUOUS CODE 62.

1. Record and then erase Quick Test codes.

2. Make sure the transmission fluid level is correct.

3. Warm engine to operating temperature.

4. With transmission in D range, press the Overdrive Cancel Switch (LED light should illuminate) and moderately accelerate from stop to 40 mph (64 Km/h). This will allow the transmission to shift into third gear. Hold speed and throttle opening steady for a minimum of 15 seconds.

5. Press Overdrive Cancel Switch (LED light should turn off) and accelerate from 40 mph (65 Km/h) to 50 mph (80 Km/h). This will allow the transmission to shift into fourth gear. Hold speed and throttle position steady for a minimum of 15 seconds.

6. With transmission in fourth gear and maintaining steady speed and throttle opening, lightly apply and release brake (to operate stop lamps). Then hold speed and throttle steady for an additional five second minimum.

7. Brake to a stop and remain stopped for a minimum of 20 seconds with the transmission in D range.

8. Repeat Steps 4 through 6 at least five times.

9. Perform Quick-Test and record continuous codes.
