Help with codes!
Hello all,
After replacing my battery my check engine light came on and came up with three codes:
U0100 Lost Communication with ECM/PCM A
U0121 Lost Communication With Anti-Lock Brake System (ABS) Control Module
P2158 P2158 Vehicle Speed Sensor "B"
The battery would sometimes drain overnight (the fan would turn on randomly when the engne is off) and there is currently a faulty DCM module in the drivers door. After getting it checked the first time the check engine light went off but the codes remained in the system when i scanned again. Any suggestions? Just bought this car last week.
