* How to use the Backprobe SetsConnect the backprobe adapters to the stacking patch cords, and connect the cords to a multimeter. Using the wire insulation as a guide for the contoured tip of the backprobe adapter,gently slide the tip into the connector from the wire side until it comes in contact with the terminal end ofthe ware {see section l1).
Check the No. 17 (7.5 A) tuse inthe under-dash fuse/relay box.
Reolace the tuse. and recheck.
Check for an op€n in the wire:1. Remove the radiator fan relay.2. TLrrn the ignition switch ON (ll).
3. Measure the voltage betweenthe No.4 terminalofthe radiator fan relay 4P socket andbody ground.
Repair open in the wire betweenlhe No. 17 luse and the radiatortan relay.
Check for an open in the wire:1. Make sure the A/C switch isOFF.2. Using a *Backprobe Set {T/N07SAZ - 001000A), measurethe voltage between the No. 27I20l terminal ol the PCM/ECMconnector A (32P) and bodyground with the PCM/ECM con-nectors connected.[ ]: '98 - 00 models
Repair open in the wire b€tweenthe.adiator fan ralav, the con-denser tan rolay and the PCM/ECM.
Check tor loose wires or poor con-nodions at the PCM/ECM connoc-tor A (32P1. lf the connections arcgood, substitute a known-goodPCM/ECM, and recheck. It thesymptom/indicalion goes away,r.plrce the original PCM/ECM.
