AXOD Drive Cycle Test

Record and zero continuous memory service codes. Warm engine to operating temperature. With transaxle in "D" range, lightly accelerate from a stop to 40 MPH to allow transaxle to shift into 3rd gear. Hold speed and throttle opening steady for a minimum of 15 seconds (30 seconds above 4000 feet altitude).

Shift transaxle into overdrive and accelerate lightly from 40 to 50 MPH to allow transaxle to shift into 4th gear. Hold speed and throttle opening steady for a minimum of 15 seconds.

With transaxle in 4th gear, throttle open and speed steady, lightly apply and release brakes (enough to turn on brake lights). Hold speed and throttle opening steady for an additional 15 seconds.

Brake to a stop and remain stopped for a minimum of 20 seconds with transaxle in overdrive. Perform QUICK TEST  and record continuous memory service codes.
