To disable front evaporator monitoring on your InterMotive CVC501/502-A HVAC and Fast Idle Controller, follow these steps: First, start the engine. Then, place the transmission in neutral. Next, apply and hold the Service Brake. After that, cycle the Park Brake on and off four times within five seconds. If these steps are done correctly, the on-board LEDs will flash in unison. Finally, cycle the key to save the new setting to the permanent memory. Repeating the procedure will re-enable front evaporator monitoring if needed. In Diag Mode, LED5 indicates the status of this option. For further clarification, consult the installation instructions and verify all connections. If you require additional support, InterMotive Technical Support is available at (530) 823-1048.
