BROKEN RWAL ECU LOCKING TAB
MODELS:
1988-89C/K, 1989 S/T AND M VANS
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 dip has been developed. Installation of this clip is shown in Figure 1.

Parts are expected to be available on March 13, 1989. Until then normal part
orders will not be accepted by GMSPO. Only verifiable emergency VIP orders
will be accepted. 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.
