Test N: Servo Chart


Disconnect the Cruise Control Servo and repeat tests 7, 8, 9, and on the Cruise Control Servo (male side).

^ If the measurement is now open (infinite resistance), check the Cruise Control Servo Connector and Cruise Control Module Connector for corrosion between terminals. Repair shorted wires if connectors are OK.

^ If the resistance is still low, check Cruise Control Servo terminals for corrosion between terminals. Replace if Servo terminals are OK.
