ASCD Relay
- Turn ignition off. Remove relay. Ensure continuity exists between relay terminals No. 1 and 2, and between terminals No. 3 and 4. See Fig 1. Replace relay if continuity does not exist. If continuity exists, go to next step.
- Ensure continuity does not exist between relay terminals No. 3 and 5. Replace relay if continuity exists. If continuity does not exist, go to next step.
- Using a fused jumper wire connect battery voltage to relay terminal No. 1. Using another jumper wire connect relay terminal No. 2 to ground. Ensure continuity exists between relay terminals No. 3 and 4, and not between relay terminals No. 3 and 5. If continuity is as specified, relay is okay. Replace relay if continuity is not as specified.
