Code C152D Mercedes-Benz Description

The ESP, ABS, and SBC systems rely on information from the EZS (Electronic Ignition Switch) module. If communication is interrupted, delayed, or corrupted, the control module stores code C152D. This does not necessarily mean the EZS module is defective. In many cases the fault is caused by low battery voltage, poor grounds, CAN bus wiring issues, loose connectors, or another control module disrupting network communication.

When C152D is present, drivers may experience warning messages such as ESP Defective, ABS Visit Workshop, or Service Brake messages. The fault is commonly found together with other communication or voltage-related codes, especially on W211 E-Class vehicles.
