Circuit/System Verification
Manual Transmission
- Ignition ON, perform the Auxiliary Gauge Sweep test with the scan tool, verify all auxiliary gauges sweep from the low to high positions.
- If none of the auxiliary gauges sweep properly
Refer to Auxiliary Gauges Malfunction .
- If one, two, or three of the auxiliary gauges sweep properly
Replace the P26 Auxiliary Gauge Module.
- If all auxiliary gauges sweep properly
- If none of the auxiliary gauges sweep properly
- Verify the Transmission Temperature Gauge display matches the Auxiliary Gage Module scan tool Transmission Fluid Temperature parameter.
- If the transmission fluid temperature gauge does not match the scan tool parameter
Replace the P26 Auxiliary Gauge Module.
- If the transmission fluid temperature gauge matches the scan tool parameter
- If the transmission fluid temperature gauge does not match the scan tool parameter
- Verify the scan tool Transmission Fluid Temperature parameter is between -74 and +174°C (-101 and +345°F) and changes with transmission temperature changes.
- If parameter is not between -74 and +174°C (-101 and +345°F) or changes with transmission temperature changes
Refer to Circuit/System Testing- Manual Transmission.
- If parameter is between -74 and +174°C (-101 and +345°F) and changes with transmission temperature changes
- If parameter is not between -74 and +174°C (-101 and +345°F) or changes with transmission temperature changes
- All OK.
Automatic Transmission
- Ignition ON, perform the Auxiliary Gauge Sweep test with the scan tool, verify all auxiliary gauges sweep from the low to high positions.
- If none of the auxiliary gauges sweep properly
Refer to Auxiliary Gauges Malfunction .
- If one, two, or three of the auxiliary gauges sweep properly
Replace the P26 Auxiliary Gauge Module.
- If all auxiliary gauges sweep properly
- If none of the auxiliary gauges sweep properly
- Verify the Transmission Temperature Gauge display matches the Transmission Control Module scan tool Transmission Fluid Temperature parameter.
- If the transmission fluid temperature gauge does not match the scan tool parameter
Replace the P26 Auxiliary Gauge Module.
- If the transmission fluid temperature gauge matches the scan tool parameter
- If the transmission fluid temperature gauge does not match the scan tool parameter
- Verify the scan tool Transmission Fluid Temperature parameter is between -74 and +174°C (-101 and +345°F) and changes with transmission temperature changes.
- If parameter is not between -74 and +174°C (-101 and +345°F) or changes with transmission temperature changes
Refer to DTC P0711-P0713 .
- If parameter is between -74 and +174°C (-101 and +345°F) and changes with transmission temperature changes
- If parameter is not between -74 and +174°C (-101 and +345°F) or changes with transmission temperature changes
- All OK.
