BROKEN RWAL ECU LOCKING TAB INSTALL LOCK TAB SERVICE CLIP

1988-89 C/K, 1989 S/T 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.

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.
