Verify Pin 4 receives positive voltage when the vehicle is actively working. Severe battery voltage drop under load.
When installing or servicing the module, it is critical to refer to the specific Curtis technical manual for the correct wiring diagrams and protection protocols. Because critical components are exposed on standard modules, users must ensure the packaging provides adequate protection for the intended operating environment.
