On a 2003 SSEi, I get Intermittent ABS, Brake, and Trac Off lights, with "Service Stability System on the DIC. It will come on and off randomly as I'm driving. Had the codes read - came up with C1298: PCM Class 2 Serial Data Link Malfunction.
At first I thought it was going to be the ABS Module. But now I'm not so sure.
Anybody ever have any experience with that code?
