Hello I have a 2002 Lincoln LS V8 that the check advancetrac message and light were on and stayed on, we scanned the codes and got C1285, C1286 and C1287 we determined the IVD electric solenoid in the brake booster needed to be replaced so we replaced the whole unit. We flashed IVD stability control module, which then cleared the DTC's and reset turning the MIL's. It did an SWA lock to lock and a booster learn. This resolved all issues for 24 hours and now the light flashes constantly. short of reflashing ABS module and short of flashing ECM Has anybody had this issue? and what did you do to solve this problem?
