About B1169

B1169 is a manufacturer-specific body diagnostic trouble code recorded for Honda vehicles. It belongs to the B-prefix family of codes, which covers body, interior, airbag, or comfort-electronics faults.

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.

B1169 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 Gauge Control Module (instrument cluster) communicates with the Powertrain Control Module (PCM) over the vehicle communication bus to receive critical data such as engine speed, coolant temperature, vehicle speed, and malfunction indicator status. DTC B1169 is stored when the Gauge Control Module does not receive valid or timely messages from the PCM within a specified monitoring window, or when corrupted data frames are detected on the bus. The cluster relies on this PCM data to drive the tachometer, temperature gauge, and the check engine lamp among other displays. When this code is set,...
