Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information UEM-003D

Condition
The upper electronic module (UEM) uses the same power stages and outputs for interior lighting in several different models. Diagnostic trouble code (DTC) UEM-003D indicates faults in various units, depending on whether the car is a V70, XC70 or an XC90. In the V70 and XC70, faults are indicated by the control signal from the cargo compartment lighting. In the XC90, faults are indicated by the control signal from the 3rd row reading lamps.
Diagnostic trouble code (DTC) UEM-003D is stored if the control module registers that the control signal to the cargo compartment lighting/third row reading lamps is too high.
Diagnostic trouble code (DTC) UEM-003D can be diagnosed in ignition position II and when the general roof lighting is lit and the cargo compartment lighting/third row reading lighting is not lit.
