Resetting Adaptive Parameters

Because the PCM has the ability to adapt to various transaxle conditions, it is necessary to reset the adaptive parameters after certain repairs have been performed. The adaptives can be reset using the Service Stall System (SSS) or using a Scan tool. The adaptives should only be reset after the following repairs have been made:

Important

When replacing the PCM for an engine related problem the transaxle adaptives should be transferred from the old PCM to the new PCM.

After performing a repair, the vehicle must be driven to allow the adaptives to learn new shift times and pressures before returning the vehicle to a customer. Refer to Learn-In procedure below.

Learn-In Procedure

If one of the repairs mentioned has been performed, then the adaptives should be reset using the SSS or using a Scan tool. Also, the vehicle must be driven, preferably on a highway, according to the following steps. By following these steps, the adaptives will be properly learned prior to returning the vehicle to the customer.

  1. Warm up the transaxle fluid temperature above 45°C (113°F).
  2. Perform 10 sets of upshift (1-2, 2-3, 3-4) at 30% throttle:
