Learn-In Procedure


If a repair mentioned has referred you to "reset the adaptives" or "perform learn-in procedure", then the adaptives should be reset using the Saturn SSS or 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. Place shift mode switch in the normal mode position.

2. Warm up transaxle (oil temp. above 45°C [113°F).

3. Perform 10 sets of upshift (1-2, 2-3, 3-4) at 30% throttle:

^ For DOHC (LL0) Engine

a. While coasting at 56 km/h (35 mph) slowly accelerate to half throttle to achieve a 4-3 downshift.

b. With selector in D3 while coasting at 32 km/h (20 mph) slowly accelerate to 75% throttle to achieve a 3-2 downshift.

Repeat both procedures five times.
