CAUTION:
^ All airbag system wiring harnesses and connectors are colored yellow. Do not use an electric test equipment on these circuits.
^ 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 a pin more than 0.65 mm (0.026 inch) diameter.
