Powertrain Control Module

NOTE: DO NOT program a control module unless you are directed by a service procedure or you are directed by a Technical Service Bulletin (TSB). Programming a control module at any other time will not permanently correct a customer's concern.

After replacing Powertrain Control Module (PCM) or if program needs to be updated, refer to latest Techline information on PCM reprogramming. After reprogramming, perform CRANKSHAFT POSITION SENSOR SYSTEM VARIATION LEARN PROCEDURE  and PROGRAMMING THEFT DETERRENT SYSTEM COMPONENTS . Also perform INSPECTION/MAINTENANCE COMPLETE SYSTEM SET PROCEDURE  under INSPECTION/MAINTENANCE PROCEDURES.
