About B1160

B1160 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.

B1160 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.

These messages carry data that the cluster displays to the driver, including road speed, engine RPM, coolant temperature, fuel level, and warning indicators. DTC B1160 is logged when the cluster fails to receive valid network frames within the expected timeout period, typically 1 to 2 seconds, during key on or engine running conditions, indicating a loss of comm...
