Speedometer Inspection


Using a speedometer tester

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.)

1.  Adjust the tire pressure to the specification. (See WHEEL AND TIRE SPECIFICATION.)

2.  Using a speedometer tester, verify that the values are as indicated in the table.

•  If not as indicated in the table, perform the DTC inspection for the PCM and DSC HU/CM, and inspect the related wiring harnesses. (See DTC INSPECTION.)
―  If the PCM, DSC HU/CM, and related wiring harnesses are normal, replace the instrument cluster. (See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.)


Using the M-MDS

1.  Connect the M-MDS to the DLC-2.

2.  After vehicle identification, select the following items from the initialization screen of the M-MDS.

(1)  “Toolbox”
(2)  “Diagnosis”
(3)  “Data Logger”
(4)  “IC”

3.  Using the simulation function SPD_MTR, verify that the values are as indicated in the table.

•  If not as indicated in the table, inspect the related wiring harnesses.
―  If the related wiring harnesses are normal, replace the instrument cluster. (See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.)
