ABS/VDC CAN DIAGNOSIS INFORMATION
This bulletin has been amended. See AMENDMENT HISTORY on the last page.
Please discard previous versions of this bulletin.
APPLIED VEHICLES: All 2005-2023 Nissan vehicles with ABS and/or VDC except:
2023 ARIYA (FE0), 2022-2023 Pathfinder (R53), 2021-2023
Rogue (T33), and 2020-2023 Sentra (B18)
SERVICE INFORMATION
When diagnosing a vehicle with an ABS or VDC SLIP warning light ON and with DTCs
stored in the ABS/VDC actuator control unit, perform DTC diagnosis first.

Do not replace the ABS/VDC actuator control unit without being supported by the
DTC diagnosis.

Do not erase DTCs before performing DTC diagnosis.

Always fully diagnose before performing any repairs.
When DTC U1000 (CAN COMM CIRCUIT) is the only DTC stored in the ABS/VDC actuator
control unit, use the REPAIR FLOW CHART starting on page 2. This will assist
in proper diagnosis results and repairs in addition to using diagnostic information in the
Electronic Service Manual (ESM).

If DTC U1000 is found stored in other systems, refer to NTB10-066 and the
applicable ESM.

If other DTCs are found stored in ABS/VDC along with U1000, follow the diagnosis
steps for those DTCs in the applicable ESM.
CLAIMS INFORMATION
Refer to the current Nissan Warranty Flat Rate Manual and use the appropriate claims
coding for repairs performed.
Nissan Bulletins are intended for use by qualified technicians, not 'do-it-yourselfers'. Qualified technicians are
properly trained individuals who have the equipment, tools, safety instruction, and know-how to do a job
properly and safely. NOTE: If you believe that a described condition may apply to a particular vehicle, DO
NOT assume that it does. See your Nissan dealer to determine if this applies to your vehicle.
