New Holland Guardian SP310F Common Problems This Manual Covers
Engine Air Filter Clogged alarm on the display
Electronic modules testing lists the Engine Air Filter Clogged alarm with the filter and level tests. It gives the cause as a clogged or dirty air filter, and the fix is to replace the filter. The Engine chapter covers the air cleaner. Fault code 3005 (DTC 4B84) covers a clog or a circuit failure.
Manual Section: Electronic modules - Testing - Engine Air Filter Clogged p. 1016Cab Electrical Center alarm
Electronic modules testing traces the Cab Electrical Center alarm to blown fuses in the fuse/relay panel, and the fix is to replace the blown fuse. The Electrical System chapter covers power distribution, fuses and relays and grounding.
Manual Section: Electronic modules - Testing - Cab Electrical Center p. 1016Brake Pressure Low alarm
Electronic modules testing says that if brake pressure is less than 14 bar (200 psi), you find the source of the low brake pressure. Check the brake lines and repair as required. After the repair, Brakes and Controls covers the pressure accumulator and service brake calibration.
Manual Section: Electronic modules - Testing - Brake Pressure Low p. 1025HVAC Thermostat Error (short)
Electronic modules testing lists the HVAC Thermostat Error (short) with the HVAC diagnostics. It says the thermostat is not operating properly, and the fix is to replace the thermostat. Cab Climate Control covers the heater core, evaporator and expansion valve. HVAC Control System covers blower removal and the heater box cover.
