Transmission Drive Cycle Test

After performing the Quick Test, use the following Drive Cycle Test for checking AX4S continuous codes:

Note: The Transmission Drive Cycle Test must be followed exactly.


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 DRIVE, press TCS (LED lamp should illuminate) and moderately accelerate from stop to 64 km/h (40 mph). This allows transaxle to shift into third gear. Hold speed and throttle open steady for a minimum of 15 seconds (30 seconds above 4000 ft).
5. Press TCS (LED lamp should turn OFF) and accelerate from 64 km/h (40 mph) to 80 km/h (50 mph). This allows transaxle to shift into fourth gear. Hold speed and throttle position steady for a minimum of 15 seconds.
6. With transaxle 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.
7. Brake to a stop and remain stopped for a minimum of 20 seconds.
8. Repeat Steps 4 through 7 at least five times.
9. Perform Quick Test and record continuous codes.
