8. Error Fault Codes P0170 occurred 14 times, the rest of these codes occurred 1 time. P0520, P0600, P0730, P2545, U0126, U1101, U1150, U1160. I could not really tell if the last 4 codes started with a U or V. Can anyone tell me what these codes mean?
P0170 - ECM - Lambda regulation high limit
P0520 - ECM - Engine oil pressure circuit malfunction
P0600 - ECM - Communication problem detected by ECM
or
P0600 - ECM - Communication fault with VCM, no response
or
P0600 - ECM - Communication fault with cluster, no response
or
P0600 - ECM - Communication sensing coding error
P0730 - ECM - Gear position sensor in invalid range
or
P0730 - ECM - Incorrect gear ratio
P2545 - ECM - VSS failure
or
P2545 - ECM - VSS message counter error
or
P2545 - ECM - VSS plausibility error
or
P2545 - ECM - VSS light on
U0126 - DPS - SAS communication fault
or
U0126 - VCM - Lost communication with Steering Angle Sensor
U1101 - VCM - CANbus failure, VCM not able to send messages on CANbus anymore
U1150 - VCM - Lost communication with VCM
U1160 - VCM - Lost communication with yaw rate sensor YAW
Sounds like some repeated communications problems. An aftermarket cruise system could induce these. Perhaps your cruise unit has failed. Could also be a bad ECM or a wiring problem.
