Circuit/System Testing

WARNING: This page is about a different variant/trim than selected.
    NOTE:

    It may take up to 2 min for all vehicle systems to power down before an accurate ground or low reference circuit continuity test can be performed.

  1. Ignition/Vehicle & All vehicle systems - Off
  2. Disconnect the electrical connector: X175 Inline Harness Connector @ T12 Automatic Transmission Assembly
    3. NOTE:

    Testing for steps 3 to 7 is performed on the control module K71 side of the harness connector.

  3. Test for less than 10 ohms between the test points: Low Reference circuit terminal 11@X175 Inline Harness Connector & Ground
    • If 10 ohms or greater 
    1. Disconnect the electrical connector: K71 Transmission Control Module
    2. Test for less than 2 ohms between the test points: Low Reference circuit terminal 11@X175 Inline Harness Connector & The other end of the circuit@Control module harness
      • If 2 ohms or greater - Repair the open/high resistance in the circuit.
      • If less than 2 ohms - Replace the component: K71 Transmission Control Module
    • Go to next step: If less than 10 ohms 
  4. Ignition - On / Vehicle - In Service Mode
  5. Verify the scan tool parameter: Transmission Fluid Temperature = Colder than -39°C (-38°F)
    • If -39°C (-38°F) or warmer 
    1. Ignition/Vehicle - Off
    2. Disconnect the electrical connector: K71 Transmission Control Module
    3. Test for infinite resistance between the test points: Signal circuit terminal 12@X175 Inline Harness Connector & Ground
      • If less than infinite resistance - Repair the short to ground on the circuit.
      • If infinite resistance - Replace the component: K71 Transmission Control Module
    • Go to next step: If colder than -39°C (-38°F) 
  6. Connect a 3 A fused jumper wire between the test points: Signal circuit terminal 12 & Low Reference circuit terminal 11@X175 Inline Harness Connector
  7. Verify the scan tool parameter: Transmission Fluid Temperature = Warmer than 129°C (264°F)
    • If 129°C (264°F) or colder 
    1. Ignition/Vehicle - Off & Remove - Jumper wire (s)
    2. Disconnect the electrical connector: K71 Transmission Control Module
    3. Ignition - On / Vehicle - In Service Mode
    4. Test for less than 1 V between the test points: Signal circuit terminal 12@X175 Inline Harness Connector & Ground
      • If 1 V or greater - Repair the short to voltage on the circuit.
      • Go to next step: If less than 1 V
    5. Ignition/Vehicle - Off
    6. Test for less than 2 ohms between the test points: Signal circuit terminal 13@X175 Inline Harness Connector & The other end of the circuit @Control module harness
      • If 2 ohms or greater - Repair the open/high resistance in the circuit.
      • If less than 2 ohms - Replace the component: K71 Transmission Control Module
    • Go to next step: If warmer than 129°C (264°F) 
  8. Ignition/Vehicle - Off
  9. Connect the electrical connector: X175 Inline Harness Connector@T12 Automatic Transmission Assembly
  10. Remove the component: Automatic Transmission Fluid Pan
  11. Disconnect the electrical connector: X176
  12. Ignition - On / Vehicle - In Service Mode
    13. NOTE:

    Testing for steps 13 to 17 is performed on the control module K71 side of the harness connector.

  13. Test for 4. 8 to 5. 2 V between the test points: Signal circuit terminal 14 & Low Reference terminal 16@X176
    • If not between 4. 8 and 5. 2 V 

      Replace the appropriate component: Automatic Transmission Wiring Harness

    • Go to next step: If between 4. 8 and 5. 2 V 
  14. Test or replace the component: B13 Transmission Fluid Temperature Sensor
