- Measure the resistance of the CMP actuator solenoid. Resistance should be between 4.8-5.2 ohms.
- Point the CMP actuator towards a shop towel. Connect a jumper wire between the CMP actuator low reference circuit at the solenoid and ground. Connect a fused jumper wire to the CMP actuator high control circuit at the solenoid. Momentarily touch the fused jumper to battery voltage. The CMP actuator solenoid pintle should immediately extend.
