Instrument Cluster Inspection
INSTRUMENT CLUSTER INSPECTION
Speedometer
Using the input/output check mode
1. Inspect the speedometer by setting it to check code 12 of the input/output check mode. Instrument Cluster Input/Output Check Mode
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 (vehicles with ABS), DSC HU/CM (vehicles with DSC) and related wiring harnesses.
- If the ABS HU/CM (vehicles with ABS), DSC HU/CM (vehicles with DSC) and related wiring harnesses are normal, replace the instrument cluster.
Tachometer
Using the input/output check mode
1. Inspect the tachometer by setting it to check code 13 of the input/output check mode. Instrument Cluster Input/Output Check Mode
Using M-MDS
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. Compare the data monitor item (RPM) with the tachometer indication.
- If the tachometer does not operate properly, inspect the PCM and related wiring harnesses.
- If the PCM and related harnesses do not have any malfunction, replace the instrument cluster.
Variable red zone
1. Connect the M-MDS to the DLC-2.
2. Measure the engine coolant temperature using the PCM data monitor item "ECT".
3. Verify that the variable red zone is displayed according to the table.
- If the variable red zone is not displayed normally, verify if the PCM and instrument cluster DTCs are output using the M-MDS.
- If any DTCs are output, perform the corresponding DTC inspection.
- If any DTC is not output, replace the instrument cluster.
Fuel gauge
Using the input/output check mode
1. Inspect the fuel gauge by setting it to check code 23 of the input/output check mode. Instrument Cluster Input/Output Check Mode
Using M-MDS
1. Connect the M-MDS to the DLC-2.
2. Measure the fuel amount in the fuel tank using the PCM data monitor item "FLI".
3. Verify that the Fuel gauge is displayed according to the table.
- If the fuel gauge does not operate or the indication is not within the allowable range, inspect the fuel gauge sender unit and its related wiring harnesses.
- If the fuel gauge sender unit and the related wiring harnesses do not have any malfunction, replace the instrument cluster.
Water temperature gauge
Using the input/output check mode
1. Inspect the water temperature gauge by setting it to check code 25 of the input/output check mode. Instrument Cluster Input/Output Check Mode
Using M-MDS
1. Connect the M-MDS to the DLC-2.
2. Measure the engine coolant temperature using the PCM data monitor item "ECT".
3. Verify that the Water temperature gauge is displayed according to the table.
- If the water temperature gauge does not operate or the indication is not within the allowable range, inspect the PCM, engine coolant temperature sensor, and related wiring harnesses.
- If the PCM, engine coolant temperature sensor and related wiring harnesses do not have any malfunction, replace the instrument cluster.
