Case 4: Data Bus Issues
with Dave Hobbs Clip





High speed CAN bus diagnostic resistance check (1 of 4)
(Video 1 of 4) A demonstration of diagnosing a HS CAN bus fault on a 2005 Chevrolet Cobalt. The car would intermittently begin to shift hard and erratic, flash the traction control SES lights, and at times steering was affected. It would set multiple network codes: U2100 in the PCM, TCM, PSCM, BCM and U2105, U2107 in the PSCM. Car had been to the dealer 4 times for this issue, they replaced the steering column one time, the TCM another time and usually just returned the car "unable to duplicate". Going back to basic network diagnostics I discovered this issue. Prior to the video, the terminals in question have been checked per the recommended GM procedures of grip testing and verifying the connector crimps.
