About B1244

B1244 is a manufacturer-specific body diagnostic trouble code. It belongs to the B-prefix family of codes, which covers body, interior, airbag, or comfort-electronics faults.

When B1244 is stored, the module has detected an electrical-circuit fault in the wiring, connector, or driver associated with the named component.

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.

B1244 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 rear wiper motor run relay is the electromechanical switching device that supplies battery voltage to the rear window wiper motor when the rear wiper is commanded on. The body control module or dedicated wiper control module provides a low side drive to the relay coil, pulling the coil to ground to energise the relay contacts and feed current to the motor. DTC B1244 is set when the control module detects that the relay drive circuit is faulty, typically due to an open coil, a short to ground or battery on the drive wire, or a missing response when the relay is commanded. When this code is ...
