Make: Volvo
Code: CEM-1A64
Definition:
Communication With The Differential Electronic Module (DEM).
Signal Missing
Description:
The diagnostic trouble code (DTC) is stored if the central electronic module (CEM) registers that communication with the differential electronic module (DEM) is not operating.
The diagnostic trouble code (DTC) can be diagnosed when the ignition has been on for more than 10 seconds.
Note! If CEM-1A6X diagnostic trouble codes (DTCs) are stored,
the central electronic module (CEM) must not be replaced as the diagnostic trouble code (DTC) indicates a communication fault in the Control area network!
Cause:
No power supply to the differential electronic module (DEM)
Open-circuit in the ground lead for the differential electronic module (DEM)
Contact resistance in the terminals
Open-circuit in the wiring for the CAN high speed network to the differential electronic module (DEM)
