2. PID/data monitor information for the ABS HU/CM and instrument cluster can be verified using an SST (WDS or
equivalent).
3. If there is a communication error between the ABS HU/CM and PCM, or between the instrument cluster and
PCM, even if the communication between the ABS HU/CM and the instrument cluster is normal, it is probable
that there is a malfunction in the PCM or PCM-related wiring harnesses.
