- Remove ECM control relay which is mounted to right side of instrument panel center support, under radio. Using a fused jumper wire, apply battery voltage to relay terminal No. 4. Using another jumper wire, ground relay terminal No. 2. See Fig 1.
- With relay energized, check for continuity between relay terminals No. 1 and 5. Continuity should exist until voltage is disconnected. Replace relay if continuity does not exist.
