lf the inspection for a particular code requires voltage or resistance checks at the ECM/PCM connectors, remove the right
kick panel. Pull the carpet back to expose the ECM/PCM. Remove the ABS control unit if so equipped. unbolt the EcM/
PCM bolt. Turn the ignition switch oFF, and connect the backprobe sets and a digital multimeter as described below
check the system according to the procedure described for the appropriate code(s) listed on the following pages'
The illustrationshows '96 - '98 models.
How to Use lhe Backprobe Sets
connect the backprobe adapters to the stacking patch cords, and connect the cords to a multimeter. using the wire insula-
tion as a guide for the contoured trp of the backprobe adapter. gently slide the tip into the connector from the wire side
until it comes in contact with terminal end of the wire'
