Transmission Control Systems: Service Precautions

CAUTION:
^ Supplemental Restraint System "Airbag" The airbag system wiring harness is routed near the TCM.

CAUTION:
^ All the airbag system wiring harnesses and connectors are colored yellow. Do not use an electric test equipment to check these circuits.
^ Be careful not to damage the airbag system wiring harness when performing TCM diagnostics or servicing.

^ 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 in) in order to avoid poor contact. Do not insert a pin of more than 0.65 mm (0.026 in) diameter.
