So I took my car in last week to replace my front right axle and fromt wheel bearings. After it was done the car was not drivable, it would brake on its own. The mechanic thought replacing the ABS sensor would solve it, but after replacing the car was drivable but all the dashboard warning lights came on. He suggested I take it to the dealership and have them restart the car’s computer system.
Once I took it to the dealership, they claimed the ABS sensor I just replaced was bad, so I had them replace it. Now they are saying they are receiving an error code and the VDC module needs to be replaced. I have a feeling something’s not adding up, but I’m not sure what to ask/recommend. Any advice?
Here are the technician notes I received:
REPLACED RIGHT FRONT ABS SENSOR & TEST DROVE VEHICLE. UPON TEST DRIVE, TRACTION CONTROL LIGHT STARTED TO FLASH ALONG WITH TPMS LIGHT & SPEEDOMETER WOULD NOT READ CURRENT VEHICLE SPEED. RE-SCANNED FOR DTC’S, FOUND CURRENT DTC:C2521 VEHICLE SPEED ABNORMAL. FOLLOWED DIAGNOSIS TREE, INSPECTED ALL 4 VEHICLE SPEED SENSORS WITH SUBARU SCAN TOOL LIVE MONITOR. FOUND THAT BOTH REAR SPEED SENSORS ARE READING BUT, BOTH FRONT SPEED SENSORS ARE INOP. ACCORDING TO SUBARU DIAGNOSTIC TREE, IT IS NECESSARY TO REPLACE VEHICLE DYNAMICS CONTROL MODULE (VDC) DUE TO HAVING AN INTERNAL FAULT IN VDC ASSEMBLY.
