Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information DEM-000A

Condition




The differential electronic module (DEM) continuously checks if the power supply to the control module is within its permitted range. The differential electronic module (DEM) compares the signal with the predefined parameter.
Diagnostic trouble code (DTC) DEM 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.
The diagnostic trouble code (DTC) can be diagnosed when the ignition is switched on.
