DTC Detection Logic
WARNING: This page is about a different car, the 2019 Nissan NV3500 HD and 2019 Nissan NV2500 HD. However, it is still accessible from the selected car via links, so may be relevant.
ECM receives vehicle speed signals from two different paths via CAN communication line: One is from the ABS actuator and electric unit (control unit) via the combination unit and the other is from TCM.
