Circuit/System Verification

Manual Transmission

  1. Ignition ON, perform the Auxiliary Gauge Sweep test with the scan tool, verify all auxiliary gauges sweep from the low to high positions.
    • If one, two, or three of the auxiliary gauges sweep properly 

      Replace the P26 Auxiliary Gauge Module.

    • If all auxiliary gauges sweep properly 
  2. 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 
  3. 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 
  4. All OK.

Automatic Transmission

  1. Ignition ON, perform the Auxiliary Gauge Sweep test with the scan tool, verify all auxiliary gauges sweep from the low to high positions.
    • If one, two, or three of the auxiliary gauges sweep properly 

      Replace the P26 Auxiliary Gauge Module.

    • If all auxiliary gauges sweep properly 
  2. 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 
  3. 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 
  4. All OK.
