When servicing the vehicle with the VIN you entered, the following diagnosis might be helpful if the vehicle exhibits the described symptoms.
Condition/Concern:
Dealership personnel may express confusion when servicing and replacing ABS / TCS and Active Handling System components on the C5 Corvette. This is likely due to changes from one model year to the next to the ABS system used, its mounting location, option codes used (or not used), and which equipment was available (standard or optional) on each model and year.
Correction/Recommendation:
The table below should be used to identify the as built vehicle content. Note: Active Brake Control (Active Handling) is standard equipment for 2001 AND NEWER (including ZO6) and is no longer called out on the 2002 AND NEWER SPID Label / VISS System.
