Continuity between
Inlet (IV) or Outlet
(OV) and battery
voltage or another
modulator wire
(short circuit) is
detected.
• Verify valve resistance of 4.0-9.0 ohm between IV to ground and OV to ground for 12v
system (11.0-21.0 ohms for 24v system).
• Verify resistance through harness and valve together is the same as valve by itself.
• Verify no voltage between Inlet/Outlet circuit and ground at the valve.
• Verify no voltage through the harness with ECU unplugged and Key ON.
• Check for corroded or damaged wiring between the ECU and the modulator valve.

ECU has detected
that Inlet (IV), Outlet
(OV) or both are not
connected.
• Verify valve resistance of 4.0-9.0 ohm between IV to ground and OV to ground for 12v
system (11.0-21.0 ohms for 24v system).
• Verify resistance through harness and valve together is the same as valve by itself.
• Check if connectors are fully seated and verify no open connections.
• Check for corroded or damaged wiring between the ECU and the modulator valve.
