Transmission Control Systems: Service Precautions

CAUTION
1. Supplemental Restraint System "Airbag"

The airbag system wiring harness is routed near the TCM

CAUTION:
^ 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.

2. 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 a pin of more than 0.65 mm (0.026 inch) diameter.
