Wiring Continuity Check
Turn ignition off. Disconnect EVO actuator valve harness connector. Check the continuity of circuit No. 330 (Yellow/Light Green wire) and circuit No. 353 (Light Blue wire) from EVO actuator valve harness connector to EVO control module pin No. 14. If continuity exists, proceed to QUICK TEST B4 . If continuity does NOT exist, service wires and proceed to QUICK TEST A1 .
Harness Short Circuit To B+ Check
Turn ignition to RUN position. Disconnect EVO actuator valve harness connector at power steering pump. Measure voltage across pin No. 13 (Yellow/Light Green wire) and pin No. 5 (Black wire). Measure voltage across pin No. 14 (Light Blue wire) and pin No. 5. If voltage is more than 5 volts, a short is indicated. Service wires as necessary and proceed to QUICK TEST A1 . If voltage is less than 5 volts, proceed to QUICK TEST B9 .
