I just replaced the crank and cam sensors plus the exhaust cam actuator control solenoid in my 2006 Trailblazer (53,000 miles) and need to perform a crankshaft angle sensor (C.A.S.E.) relearn.
Does anyone have a Tech 2 that can assist me with this since the manual process is a pain in the balls. Willing to pay/supply beer for the quick job?
Thanks!
Manual process:
- Turn off all of the accessories. With the Air temperature sensor and Coolant temperature within 5 degrees (Centigrade) of each other, start the engine and let it idle in Park or Neutral for two minutes.
- Accelerate the vehicle to 55 mph at part throttle. Cruise at 55 mph for 8- 10 minutes until the engine reaches operating temperature.
- Cruise at 55 mph for another 5-6 minutes.
- Decelerate to 45 mph without using the brakes, and maintain 45 mph for 1 minute.
- Perform 4 deceleration cycles, without using the brakes, of 25 seconds each where no specific speed is necessary. Returning to 45 mph for 15 seconds in between deceleration cycles.
- Accelerate to 55 mph and cruise for 2 minutes.
- Stop the vehicle and idle for 2 minutes with the brake applied and the transmission in Drive (automatic trans.) or Neutral (manual trans.) with the clutch depressed.
