Communication fault
Diagnostic procedure
| 1. |
Clear the diagnostic
trouble code and then leave the ignition switch in the ON position for about 1 minute to check
whether the DTC is generated afresh.
|
|
| 2. |
If the DTC is generated afresh, try fitting a new SID unit. If the DTC is again
generated with the new SID unit, the fault could be in the main instrument display panel or the
ACC. Read their diagnostic trouble codes and proceed with fault diagnosis in these systems.
