• Be careful not to damage airbag system wir-
ing harness when performing diagnostics and
servicing the TCM.

When measuring 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 the pin more
than 0.65 mm (0.0256 in).
