Continuity Tests
- Disconnect negative battery cable. Remove motor relay from hydraulic unit. Ensure continuity exists between terminals "B" and "C" of motor relay. See Fig 1 . Connect 12 volts to terminal "C", and ground terminal "B". Ensure continuity exists between terminals "A" and "D".
- Replace relay if continuity is not as specified. If continuity is as specified, check wiring harness between motor relay and ABS control unit fuse (60 amps).
