Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information ECM-5000

Condition




This diagnostic trouble code (DTC) is stored if the engine control module (ECM) registers a short-circuit to ground or supply voltage or an open-circuit in the signal cable for the air conditioning (A/C) pressure sensor.

Substitute value
- The engine cooling fan (FC) is activated at the predefined speed
- Air conditioning (A/C) shut off
- The A/C pressure is calculated at approximately 700 kPa.

Possible source

Signal too high
- Short-circuit to supply voltage in the signal cable
- Damaged A/C pressure sensor.

Signal too low
- Short-circuit to ground in the signal cable
- Open-circuit in the signal cable
- Damaged A/C pressure sensor.

Fault symptom[s]
- The air conditioning (A/C) compressor does not start, or runs sporadically.
