Transmission Control Systems: Service Precautions

CAUTION
^ Supplemental 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 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 the ECM, TCM or each sensor, use a tapered pin with a 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 (0.0256 inch).
