Fail-Safe Relay Test

NOTE: Fail-safe relay is part of ABS relay. If fail-safe relay is defective, replace ABS relay.
  1. Using ohmmeter, measure resistance between terminals "C" and "D" of ABS relay. See Fig 1 . Resistance should be 60-100 ohms. If resistance is not as specified, replace ABS relay. If resistance is as specified, go to next step.
  2. Using ohmmeter, check continuity between terminals "A" and "E" of ABS relay. See Fig 1 . Continuity should exist. Also, check continuity between terminals "B" and "E" of ABS relay. Continuity should not exist. If continuity is not as specified, replace ABS relay. If continuity is as specified, go to next step.
  3. Apply 12 volts to terminal "D" and ground terminal "C" of ABS relay. See Fig 1 . Using ohmmeter, check continuity between terminals "A" and "E" of ABS relay. Continuity should not exist. Also, check continuity between terminals "B" and "E" of ABS relay. Continuity should exist. If continuity is not as specified, replace ABS relay.
