Micro-ISO Relays
- Remove relay to be tested. Wiper on/off relay is located in battery junction box. Washer pump relay is located in relay box. See COMPONENT LOCATIONS
. Check relay continuity. Continuity should exist between relay terminals No. 1 and 2, and between relay terminals No. 3 and 4. See Fig 1
. Continuity should not exist between relay terminals No. 3 and 5. If continuity is as specified, go to next step. If continuity is not as specified, replace relay.
- Using a jumper wire, apply battery voltage to relay terminal No. 1. Using a second jumper wire, ground relay terminal No. 2. Continuity should now exist between relay terminals No. 3 and 5. If continuity is not as specified, replace relay. If continuity is as specified, relay is okay at this time.
