Symptom

Component named as the cause

Work done

A ribbon is as wide as the records that state both of its ends (only the commonest are drawn). A record that names several symptoms or components runs through each. Orange is records that say the fault came back or was not fixed. Results come from owners’ reports only; one that does not say is “result not stated”. None of this is a likelihood of a cause or a rate at which work succeeds.

      2. Confirm that the original size tires and wheels are fitted and that the axle ratio is as specified on the SPID label and has not been modified.
      3. If those are correct and the odometer is beyond the limit, look at the relationship between the VSS and the reluctor on the transmission output shaft, and inspect the associated wiring and connectors closely.

    3. 3Correction

      Repair

      • Finally, it may be necessary to exchange the instrument panel cluster (IPC) for a replacement unit.

      Caution
