BROKEN RWAL ECU LOCKING TAB INSTALL LOCK TAB SERVICE CLIP

Model and Year 1988-89 C/K TRUCK 1989 S/T TRUCK AND M-VAN

Some vehicles may experience a condition where the rear wheel anti-lock (RWAL) ECU module locking tabs may break when the tab is bent back to remove the ECU module. In the past, this condition would then require the replacement of the ECU module.

To eliminate this costly component replacement, an ECU module locking tab service clip has been developed. Installation of this clip is shown in Figure 1.

SPO will make every effort to obtain parts. All parts will be placed on 400 control to waive VIP surcharges. However, the part will be shipped premium transportation at dealer's expense. All other order types will be canceled as incorrectly ordered while the 400 control is in place.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
