CAUTION:
^ All airbag system wiring harnesses and connectors are colored yellow. Do not use an electric test equipment on these circuits.

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.
