MPI Control Relay (Mirage 1.6L, Eclipse 1.8L & 2.0L VIN R & U, Galant 2.0L VIN R, Montero, Pickup, Ram-50 & Sigma 3.0L)
- For relay location, see MPI CONTROL RELAY LOCATION table. Check for battery voltage at terminal No. 10 of relay connector. See Figure -Figure .
- If battery voltage is present, go to step 3). If battery voltage is not present, check circuit between relay and battery, including fusible link No. 1.
- Apply battery voltage to terminal No. 10. Battery voltage should NOT be present at terminals No. 4 and 5. Apply battery voltage to terminal No. 10 and ground terminal No. 8. Battery voltage should be present at terminals No. 4 and 5.
- Apply battery voltage to terminal No. 3. Battery voltage should NOT be present at terminal No. 2. Apply battery voltage to terminal No. 3 and ground terminal No. 7. Battery voltage should be present at terminal No. 2.
- Apply battery voltage to terminal No. 9. Battery voltage should NOT be present at terminal No. 2. Apply battery voltage to terminal No. 9 and ground terminal No. 6. Battery voltage should be present at terminal No. 2. Replace relay if it does not test as specified.
