System: Body  |  Type: Manufacturer-Specific  |  Make: Holden

About B357D

B357D is a manufacturer-specific body diagnostic trouble code recorded for Holden vehicles. It belongs to the B-prefix family of codes, which covers body, interior, airbag, or comfort-electronics faults.

When B357D is stored, the module has detected a short-circuit (voltage pulled to ground or to supply) in the monitored circuit.

Scanning & clearing: Body (B) codes are often stored in the body control module, airbag module, or climate module. A basic OBD-II tool usually will not read body codes — an enhanced or OEM-level scan tool is typically required.

B357D 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

The Body Control Module (BCM) controls and monitors heating element control circuit 2, switching the second heating element on and off and watching the circuit voltage to confirm the commanded state. DTC B357D is set when the BCM detects battery voltage on control circuit 2 while the output is commanded off, or a sustained voltage above the calibrated limit. This indicates a short to battery on the circuit 2 control wire that can keep the second element powered when it should be off. When this code is set the technician may notice the heated component staying on continuously, failing to switch...
