Brake Fluid Pump Relay: Testing and Inspection

Fig. 69 ABS Fail Safe Relay Terminal Identification:

When testing ABS Motor relay refer to Fig. 69 for terminal identification of ABS connector.
1. Measure resistance between terminals E and H or between A and H of relay box connector, resistance should be between 50 - 90 ohms.
2. Check between terminals B and F, continuity should not exist.
3. Apply 12 Volts to terminals G and H. When applying voltage connect battery positive to terminal H. Check between terminals B and F, continuity should exist.
4. If relay is not as specified, replace.
