INSTRUMENT CLUSTER INSPECTION

Speedometer

Using a speedometer tester

1. Adjust the tire pressure to the specification.

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

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

- If the speedometer does not move or the indication is not within the allowable range, inspect the PCM, ABS HU/CM (with ABS) or DSC HU/CM (with DSC), and related wiring harnesses.

- If the PCM, ABS HU/CM (with ABS) or DSC HU/CM (with DSC), 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 the vehicle is identified, select the following items from the initialization screen of the M-MDS.

- When using the IDS (laptop PC)

1 Select "DataLogger".
2 Select "Modules".
3 Select "IC".

- When using the PDS (Pocket PC)

1 Select "Module Tests".
2 Select "IC".
3 Select "DataLogger".

3. Verify that it is displayed according to the table using "SPDMTR".

- If the speedometer does not move or the indication is not within the allowable range, inspect the related wiring harnesses.

- If the related wiring harnesses are normal, 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 the vehicle is identified, select the following items from the initialization screen of the M-MDS.

- When using the IDS (laptop PC)

1 Select "DataLogger".
2 Select "Modules".
3 Select "IC".

- When using the PDS (Pocket PC)

1 Select "Module Tests".
2 Select "IC".
3 Select "DataLogger".

3. Verify that it is displayed according to the table using "TACHOMTR".

- If the tachometer does not move or the indication is not within the allowable range, inspect the related wiring harnesses.

- If the related wiring harnesses are normal, replace the instrument cluster.





Fuel gauge

1. Connect the M-MDS to the DLC-2.






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

- When using the IDS (laptop PC)

1 Select "DataLogger".
2 Select "Modules".
3 Select "IC".

- When using the PDS (Pocket PC)

1 Select "Module Tests".
2 Select "IC".
3 Select "DataLogger".

3. Verify that it is displayed according to the table using "LCD_SEG".

- If any of the segments are not displayed, replace the instrument cluster.






Boost gauge

1. Connect the M-MDS to the DLC-2.






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

- When using the IDS (laptop PC)

1 Select "DataLogger".
2 Select "Modules".
3 Select "IC".

- When using the PDS (Pocket PC)

1 Select "Module Tests".
