ABS Main Relay: Testing and Inspection

Fig. 69 ABS Fail Safe Relay Terminal Identification:

When testing fail safe relay refer to Fig. 69 for terminal identification of ABS connector.
1. Measure resistance between terminals C and D of ABS relay connector, resistance should be between 60-100 ohms.
2. Check between terminals A and E, continuity should exist, then check between terminals B and E, continuity should not exist.
3. Apply 12 volts to terminals D and C, check between terminals B and E, continuity should exist. Check between terminals A and E, continuity should not exist.
4. If relay is not as specified, replace.
