Date: 040914
Recall - PCM Failure Caused by Electronic Suspension
Product Safety - Electronically Controlled Air Suspension/Powertrain Control Module # 04048A - (Sep 14, 2004)
Models:
2002 GMC Envoy
2002 Oldsmobile Bravada
Equipped with Electronically Controlled Air Suspension (RPO G67)
THIS BULLETIN IS BEING REVISED TO CLARIFY THE DISCONNECTION OF THE ELECTRICAL CONNECTOR FROM THE ECAS
COMPRESSOR (STEP 2 IN THE SERVICE PROCEDURE).
Condition
General Motors has decided that a defect which relates to motor vehicle safety exists in certain 2002 model year GMC Envoy and Oldsmobile Bravada
vehicles equipped with electronically controlled air suspension (ECAS) (RPO G67). Some of these vehicles have a condition in which the ECAS may
produce a brief electrical spike while the vehicle is operating. This electrical spike can disrupt the powertrain control module (PCM) causing the vehicle
to stall. If the spike damages the PCM, the vehicle may not restart. If this happens while the vehicle is moving, a crash could occur without prior
warning.
Correction
Dealers are to install a wiring harness.
Vehicles Involved
Involved are certain 2002 model year GMC Envoy and Oldsmobile Bravada vehicles equipped with ECAS (RPO G67) and built within the VIN
breakpoints shown.
Important
Dealers should confirm vehicle eligibility through GMVIS (GM Vehicle Inquiry System) before beginning recall repairs. [Not all vehicles within the
above breakpoints may be involved.]
For dealers with involved vehicles, a Campaign Initiation Detail Report containing the complete Vehicle Identification Number, customer name and
address data has been prepared and will be loaded to the GM DealerWorld, Recall Information website. Dealers that have no involved vehicles currently
assigned will not have a report available in GM DealerWorld.
The Campaign Initiation Detail Report may contain customer names and addresses obtained from Motor Vehicle Registration Records. The use of such
motor vehicle registration data for any other purpose other than follow-up necessary to complete this recall is a violation of law in several
states/provinces/countries. Accordingly, you are urged to limit the use of this report to the follow-up necessary to complete this program.
