SUBJECT: 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.
