C1024 — ESP CAN Communication With Transmission Control Module Interrupted

System: Chassis  |  Type: Manufacturer-Specific  |  Make: Mercedes-Benz

About C1024

C1024 is a manufacturer-specific chassis diagnostic trouble code recorded for Mercedes-Benz vehicles. It belongs to the C-prefix family of codes, which covers chassis, braking, steering, suspension, or stability-control faults.

Scanning & clearing: Chassis (C) codes are stored in the ABS, traction control, or stability-control modules. An enhanced or OEM-level scan tool is usually required to read and clear them.

C1024 is a manufacturer-specific code. The same code string on a different make may have a different meaning. Always confirm the code's definition against the vehicle's service information for the specific make and model under test.

Code Information

On Mercedes Benz vehicles, the Electronic Stability Program (ESP) control module communicates with the Transmission Control Module (TCM) across the powertrain CAN bus to coordinate gear holding, torque converter lockup changes, and shift inhibits during stability, traction, and ABS interventions. Code C1024 is stored when the ESP module detects that expected CAN messages from the TCM are missing for longer than a calibrated timeout, or contain corrupted or implausible data. Common triggers include damaged CAN wiring, corroded or pushed back pins at the transmission or ESP connectors, low syste...
