Speedometer

1.  Adjust the tire pressure to the specification.

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

•  If the speedometer does not operate or the indication is not within the allowable range, inspect the PCM, ABS HU/CM or DSC HU/CM, and related wiring harnesses.
―  If the PCM, ABS HU/CM or DSC HU/CM, and related wiring harnesses do not have any malfunction, replace the instrument cluster.

Tachometer

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 indication on the tachometer.

1.  Connect the M-MDS to the DLC-2.

2.  After vehicle identification, the following can be selected from the M-MDS initialization screen.

•  Using an IDS (laptop PC):
1.  “Data logger”
2.  “Module”
3.  “IC”
•  Using a PDS (Pocket PC):
1.  “Module test”
2.  “IC”
3.  “Data logger”

3.  Select “TACHOMTR” from PID/DATA Monitor Table.

4.  Verify the monitored value according to the directions on the screen.

Note
•  The PID data screen function is used for monitoring the calculated value of input/output signals in the module. Therefore, if the monitored value of the output parts is not within the specification, it is necessary to inspect the monitored value of input parts corresponding to the applicable output part control. In addition, because the system does not display an output part malfunction as an abnormality in the monitored value, it is necessary to inspect the output parts individually.

Fuel gauge

1.  Connect the M-MDS to the DLC-2.

•  Using an IDS (laptop PC):
1.  “Data logger”
2.  “Module”
3.  “IC”
•  Using a PDS (pocket PC):
1.  “Module test”
2.  “IC”
3.  “Data logger”

3.  Verify that all the segments are displayed using “LCD_SEG”.

•  If any of the segments are not displayed, replace the instrument cluster. (See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.)

4.  Disconnect the negative battery cable.

5.  Remove the rear seat cushion. (See REAR SEAT CUSHION REMOVAL/INSTALLATION.)

6.  Remove the service hole cover.

7.  Disconnect the fuel gauge sender unit connector.

8.  Connect the negative battery cable.

9.  Connect the SST (Fuel and thermometer checker) to fuel gauge sender unit connector terminals C and D.

10.  Verify the fuel gauge reading is as indicated in the table using the SST (Fuel and thermometer checker).

•  If not as indicated in the table, inspect the wiring harness.
―  If there is any malfunction, repair or replace the wiring harness.
―  If the wiring harness is normal, replace the instrument cluster.
