Transmission Control Systems: Service Precautions
CAUTIONSupplemental Restraint System "Airbag"
The airbag system wiring harness is routed near the Transmission Control Module (TCM).
CAUTION:
All airbag system wiring harness and connectors are colored yellow. Do not use an electrical test equipment on these circuit.
Be careful not to damage the airbag system wiring harness when performing diagnostics and servicing the TCM.
Measurement
When measuring the voltage and resistance of ECM, TCM or each sensor, use a tapered pin with diameter of less than 0.64 mm (0.025 inch) in order to avoid poor contact. Do not insert the pin more than 0.65 mm (0.026 inch).
