Speedometer inspection: Notes

CAUTION:
  • When only the front or the rear wheels are driven using a speedometer tester, the DSC HU/CM may determine that the vehicle speed signal is in error and the engine cannot be stopped by the normal operation. If the engine cannot be stopped, perform an emergency engine stop operation. (See SERVICE CAUTIONS .)
NOTE:
  • If a speedometer tester is unavailable and the M-MDS is used, perform the inspection following the procedure for the M-MDS.
