Drive Cycle Test
After performing the EEC-IV Quick- Test, the following drive cycle test for checking E4OD continuous codes should be performed.
NOTE: Faults have to appear four times consecutively for continuous codes 49, 59 and 69 to be set, and five times consecutively for continuous code 62.
1. Record and zero EEC-IV Quick-Test codes.
2. Verify that 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 64 km/h (40 mph). This will allow the transmission to shift into third gear. Hold speed and throttle opening steady for a minimum of 15 seconds (30 seconds above 4000 feet altitude).
5. Press overdrive cancel switch (LED light should turn off) and accelerate from 65 km/h (40 mph) to 80 km/h (50 mph). 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 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.
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 EEC-IV Quick-Test and record continuous codes.

NOTE: If any other fault codes appear, service those codes first as they could affect the electrical operation of the transmission.
NOTE: After the servicing of any fault codes resulting from the Quick- Test, the Quick-Test should be repeated.
