About B0560

B0560 is a generic (obd-ii standard) body diagnostic trouble code. 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.

Because B0560 is a generic OBD-II code, its base definition is shared across manufacturers. The specific diagnostic steps, reference values, and repair procedures can vary by vehicle, and the TaT Diagnostic Assistant includes verified procedures submitted by working technicians.

Code Information

DTC B0560 is a generic body code that indicates the instrument cluster has detected an invalid, erratic, or missing tachometer (engine RPM) input signal. On most modern vehicles the cluster receives engine RPM either as a hardwired tach pulse from the ignition coil primary or ECM tach output, or as a CAN bus message broadcast by the engine control module after being calculated from the crankshaft position sensor. The code sets when the cluster sees no RPM signal at all, an implausibly high or jittery signal, or a signal that fails to track engine cranking and running conditions. With this code...
