1) Turn ignition off. Disconnect PCM connector. See
POWERTRAIN CONTROL MODULE (PCM) LOCATION table under COMPUTERIZED
ENGINE CONTROLS. Go to next step.
2) Turn headlights on. Using DVOM, check voltage between PCM
connector terminal No. 58 and chassis ground. If battery voltage is
present, turn headlights off and go to next step. If battery voltage
is not present, check and repair circuit between headlight relay
connector and PCM connector.
3) Turn defogger switch on. Using DVOM, check voltage between
PCM connector terminal No. 58 and chassis ground. If battery voltage
is present, turn defogger switch off and go to next step. If battery
voltage is not present, check and repair circuit between defogger
relay connector and PCM connector.
4) Turn blower switch on. Using DVOM, check voltage between
PCM connector terminal No. 58 and chassis ground. If battery voltage
is present, turn blower switch off and go to next step. If battery
voltage is not present, check and repair circuit between blower switch
connector and PCM connector.
5) If battery voltage is present and preceding tests do not
show any system or component malfunction and PCM is suspected,
substitute PCM with known-good unit and retest system.
