Circuit/System Testing

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

NOTE: Circuit/System Verification must be performed before proceeding with Circuit/System Testing.

Ignition OFF and all vehicle systems OFF. Remove the K71 Transmission Control Module to disconnect the X2 harness connector. It may take up to 2 min for all vehicle systems to power down.
Test for infinite resistance between the low reference circuit terminal 7 and ground.
- If less than infinite resistance
  Replace the wiring harness.
- If infinite resistance
Ignition OFF.
Test for infinite resistance between the signal circuit terminal 8 and ground.
- If less than infinite resistance
  Replace the wiring harness.
- If infinite resistance
Test for infinite resistance between each terminal at the X2 harness connector and the terminals listed below:
- Low reference circuit terminal 7
- Signal circuit terminal 8
- If less than infinite resistance
  Replace the wiring harness.
- If infinite resistance
Test for the resistance between the B13 Transmission Fluid Temperature Sensor signal circuit terminal 8 and the low reference circuit terminal 7. Refer to Transmission Fluid Temperature Sensor Specifications for the resistance values.
- If the resistance value does not match with the Transmission Fluid Temperature Sensor Specifications
  Replace the control valve body.
- If the resistance value match with the Transmission Fluid Temperature Sensor Specifications
Replace the K71 Transmission Control Module.
