Test Circuit Check

On 2.8L models, remove connector to the ignition system control unit located on left side of pedals. Measure resistance between ground and terminal No. 12 (except 2.8L "F" engines). On "F" engine models, check resistance between terminal No. 22 and ground. In both cases reading should be infinite.
