Code Definition

C1942 — Unrecognised Powertrain Configuration

System: Chassis  |  Type: Manufacturer-Specific  |  Make: Generic

About C1942

C1942 is a manufacturer-specific chassis diagnostic trouble code. 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.

C1942 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

Chassis modules such as the ABS or stability control unit need to know the vehicle powertrain configuration, for example engine type, transmission, and drivetrain, which they hold as stored configuration data or receive over the vehicle network from the powertrain control module. DTC C1942 sets when the module reads a powertrain configuration value it does not recognise or that does not match its expected setup, for example after a module has been replaced without coding, an incorrect part has been fitted, or a network fault corrupts the configuration message. When this code is set, affected c...
