3. If the fault persists, replace the relay module.
1. Check wiring and correct any errors.
2. Check Preignition Interlock switches to assure proper functioning.
3. Check fuel valve operation.
4. Reset and sequence the relay module; monitor the Preignition Interlock status.
5. If the fault persists, replace the relay module.
1. Check wiring and correct any errors.
2. Reset and sequence the relay module.
3. Use manual motor potentiometer to drive the motor open and closed. Verify at
motor switch that the end switches are operating properly. Use RUN/TEST
switch if manual potentiometer is not available.

2. If fault reappears, remove power from the device, reapply power, then reset
and sequence the relay module.
3. If the fault persists, replace the relay module.
1. Reset and sequence the relay module.
2. If fault reappears, remove power from the device, reapply power, then reset
and sequence the relay module.
3. If fault does not repeat on the next cycle, check for electrical noise being
copied into the relay module through the external loads or possibly an
electrical grounding issue.
4. If the fault persists, replace the relay module.
1. Check wiring and operation of special OEM inputs.
2. Reset and sequence the relay module.
3. If fault reappears, remove power from the device, reapply power, then reset
and sequence the relay module.
4. If the fault does not repeat on the next cycle, check for electrical noise being
copied into the relay module through the external loads or possibly an
electrical grounding issue.
