P-1 Check For Short

Ensure ignition is off. Disconnect battery, ABS control unit and hydraulic control unit. Set ohmmeter to 200-k/ohm scale.

1. Measure resistance between hydraulic control unit Yellow/White wire and ABS control unit Black/Green wire, and between Black and Blue/Orange wires. Resistance should be greater than 10 k/ohms.
2. Measure resistance between hydraulic control unit Yellow/Red wire and ABS control unit Black/Green wire, and between Black and Blue/Orange wires. Resistance should be greater than 10 k/ohms.
3. Measure resistance between hydraulic control unit Yellow/Green wire and ABS control unit Black/Green wire, and between Black and Blue/Orange wires. Resistance should be greater than 10 k/ohms.
4. Measure resistance between hydraulic control unit Blue wire and ABS control unit Black/Green wire, and between Black and Blue/Orange wires. Resistance should be greater than 10 k/ohms.
5. Measure resistance between hydraulic control unit Black/White wire and ABS control unit Black/Green wire, and between Black and Blue/Orange. Resistance should be greater than 10 k/ohms.
6. Measure resistance between hydraulic control unit Brown wire and ABS control unit Black/Green wire, and between Black and Blue/Orange wires. Resistance should be greater than 10 k/ohms. If resistance readings are correct, reconnect battery and go to P-2 CHECK FOR SHORT TO POWER  . If resistance is not correct, repair wire(s) in question.
