L5P Diagnostic CANBUS Plugs 2020-2023

The L5P has a CANBUS system that goes from the ECM to the fuel pump driver module. If a Nox sensor or DEF module fails, it can break the CAN link and leave you guessing what component is bad. With our diagnostic CANBUS plug kit, you can simply install a plug in place of each module until the CAN link is restored. Once problem is identified, the correct module can be ordered. This method can save you time and money. Note that these are not intended to defeat or tamper with emissions equipment. Use for diagnostic purposes only.
