We are very sorry this issue has come up. Please allow us to continue diagnosis of the vehicle for you. After reviewing the repair order and speaking with the service writer, we found the vehicle had come in for two separate, unrelated concerns. One was the ABS (Antilock Brake System) light has been on and the vehicle was running poor, suffering from what seemed to be a misfire. We verified both. The running problem was addressed and a repair was made.
The ABS light was on, we found several codes in the system, however, when the components were tested, they passed. We understand there is an ABS problem with the vehicle, however we need to see or witness the fault occur in order to diagnose the issue. Simply having the ABS light on gives us NO information in these old OBD I (On Board Diagnosis - One). We cannot simply pull a code and replace a listed component. The diagnosis process leads us to testing listed components and circuits, which, again, we did, and found no faults. The issue may be in an individual component, the wiring harness, the ABS computer or pump module. We were able to make a repair on the running issue, but NEVER were able to witness the fault with the ABS system. The ABS light being on will not cause a brake issue, it is just in indication that the ABS system has sensed a fault and is shut itself off. In this case the brake system will operate like any vehicle not equipped with ABS. In a panic stop, or in wet or slippery road conditions, the wheels may skid when the brakes are applied hard, just like any vehicle without ABS.
The fees charged for the repair were for the running issue, which we did repair. No charges were incurred for the ABS system as we were unable to diagnose the problem at this time. These systems are not easily diagnosed and Chris, our chief diagnosis technician and general manager was the person working on the van. He had vacation schedules for 6 months and was leaving the Monday after the van was picked up. He is the only technician we have which will likely be able to diagnose the vehicle.
He will be back the week of July 31st, we are currently scheduling appointments for that week.
Thank you, please let us know if you have any questions.
