ECM Can Fool ABS
This bulletin applies to 2012-2017 Nissan Titan trucks. When diagnosing for DTC C1130 (engine signal), ECM related DTC P-codes must be diagnosed, repaired and DTCs erased first before proceeding with C1130.
DTC C1130 is an ABS DTC that indicates an output signal of the ECM is not recognized. Absent or incorrect ECM signals that are indicated by corresponding P-codes may trigger C1130 in the ABS control unit.
Some vehicle features that can be affected by absent or incorrect ECM signals include FEB (forward emergency braking), ICC (intelligent cruise control) and VDC/ABS/TCS.
