INSTRUMENT CLUSTER INSPECTION

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.

2.  Using a speedometer tester, verify that the tester reading is as indicated in the following table.

European (L.H.D. U.K.), General (L.H.D. R.H.D.) specs., Australian specs.

3.  Verify that the speedometer reading is within the range indicated in the table.

•  If the speedometer does not operate or the indication is not within the allowable range, inspect the DTC inspection for the following control module and the related wiring harnesses.
―  PCM
―  TCM (ATX)
―  DSC HU/CM
•  If the PCM, TCM (ATX), DSC HU/CM, and related wiring harnesses are normal, replace the instrument cluster.


Using the M-MDS

1.  Connect the M-MDS to the DLC-2.

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

(1)  “Data logger”
(2)  “Module”
(3)  “IC”

3.  Using “SPEEDOMTR”, verify that the displayed information is as indicated in the table.

European (L.H.D. U.K.), General (L.H.D. R.H.D.) specs., Australian specs.

―  DSC HU/CM
•  If the PCM, TCM (ATX), DSC HU/CM, and related wiring harnesses are normal, replace the instrument cluster.


Tachometer inspection

Caution
•  If the engine speed exceeds the allowable range, the engine could be damaged. Therefore, when inspecting the tachometer, do not allow the engine speed to exceed the allowable range indicated on the tachometer.

1.  Connect the M-MDS to the DLC-2.

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

(1)  “Data logger”
(2)  “Module”
(3)  “IC”

3.  Using “TACHOMTR”, verify that the displayed information is as indicated in the table.

•  If the tachometer does not operate or the indication is not within the allowable range, inspect the DTC inspection for the following control module and the related wiring harnesses.
―  PCM
•  If the PCM and related wiring harnesses are normal, replace the instrument cluster.


LCD Inspection


Type A
