Diagnostic trouble code (DTC) informationCEM-9F26

Condition 

The Central electronic module (CEM) powers the lighting in the cup holder/ashtray.

The power supply is a PWM signal (Pulse Width Modulated).

The diagnostic trouble code (DTC) is stored if the Central electronic module (CEM) registers that the circuit for the cup holder/ashtray lighting has a short-circuit to ground.

The diagnostic trouble code (DTC) can be diagnosed when the ignition is switched on.

Substitute Value 

• If the fault has been detected in 100 ignition cycles, the output is closed permanently until the diagnostic trouble code is erased (applies from structure week 200539).

Possible Source 

• The cables are short-circuited to each other.
• Short-circuit to ground in the power supply cable.

Fault symptom[s] 

• Interior light does not work
