Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information

Condition




The differential electronic module (DEM) checks if the power supply for the control module is within the permitted limits by comparing the signal with a calculated value.
Diagnostic trouble code (DTC) DEM-000A is stored if the control module registers a power supply lower than 8.5 V for 25 seconds or greater than 18.5 V for 3 seconds.
Diagnostic trouble code (DTC) DEM-000A can be diagnosed with the engine running and the engine speed (RPM) >500 rpm.

Substitute value
- Four wheel drive is blocked.

Possible source

Signal too high:
- Short-circuit to ground.

Signal too low:
- Open-circuit in the power supply.

Fault symptom[s]
- Four wheel drive is not functioning.
