Resistance Check

  1. Turn ignition off. Set VOM on 200 ohm scale. At ABS fail-safe relay, measure and record resistance between terminals "f" and "j". At ABS fail-safe relay, measure and record resistance between terminals "b" and "j". Resistances should be 50-90 ohms.
  2. If resistances are as specified, go to PINPOINT TEST MMR-5  . If resistances are not as specified, replace ABS fail-safe relay.
