The ECM/PCM switched-battery input reads below threshold while the ignition is on. Either the main relay does …
The ECM/PCM switched-battery input reads above the upper threshold. Most often caused by a charging system ove…
The ECU detects sporadic interruptions of its supply voltage. The fault is set when supply drops below a thres…
General electrical fault on the engine oil level sensor circuit. The ECM cannot read a plausible level signal …
The oil level sensor is electrically intact, but the level reading is implausible — for example a constant val…
The oil level sensor signal voltage reads below the lower limit, typically a short to ground or an open at the…
The oil level sensor signal voltage reads above the upper limit, typically a short to reference voltage or an …
The oil level signal jumps or drops out intermittently — usually loose contacts, vibration cracks at the sende…
The oil level monitor reports the engine oil level below the safe minimum after sensor checks pass. Continued …
The voltage reported on the main power relay sense line for the engine controller does not match expectation. …
The sense (feedback) line that lets the ECM verify the main power relay has actually closed shows intermittent…
The Event Data Recorder (EDR / black box) request line — used by the ECM or restraint module to trigger the ED…
The EDR request line reads stuck low — typically a short to ground or a permanently asserted request. The ECM …
The EDR request line reads stuck high — typically a short to battery voltage. The ECM cannot pulse the line ba…
General electrical fault in the second A/C refrigerant pressure sensor circuit. Sensor B usually monitors the …
A/C refrigerant pressure sensor B is electrically intact, but its reading does not match the system model — fo…
A/C refrigerant pressure sensor B signal voltage reads below the lower limit. Either a short to ground in the …
A/C refrigerant pressure sensor B signal voltage reads above the upper limit. Typically a short to reference v…
General electrical fault on the A/C compressor request input A. This input tells the ECM that the HVAC control…
The Power Take-Off (PTO) enable switch input to the ECM is open. PTO is used on trucks and work vehicles to dr…
The PTO enable switch input reads stuck low — typically a short to ground or a permanently closed switch. The …
The PTO enable switch input reads stuck high — typically a short to battery voltage. The ECM cannot pull the i…
The PTO engine-shutdown command line is open. This safety input lets a connected work attachment (or operator …
The PTO engine-shutdown command line reads stuck low — usually a short to ground or a permanently asserted shu…
