Nissan has released a new position statement on pre and post-vehicle diagnostic scanning and calibration.
Background on Scan Requirements
Introduced in 1996, Nissan vehicles systems have the ability to capture and record DTCs of vehicle systems within the vehicle Electronic Control Units (ECU). All 1996 to current vehicles that contain a 16-pin OBD2 port have the potential to have a diagnostic system scan. In vehicles without an OBD2 port it may be necessary to locate other vehicle data link connectors to perform this task. Nissan recommends the use of the CONSULT diagnostic scan tool with the most up-to-date software installed. Nissan North America does not test or validate other diagnostic scan tools in the market and cannot comment on their capabilities or accuracy. Using the CONSULT diagnostic scan tool, stored DTCs are identified, validated, and then addressed within the repair process.
Some additional vehicle control systems’ diagnostic and DTCs facts:
- The proliferation of vehicle control systems has increased the potential number ofDTCs beyond the point where dashboard indicators can illuminate for every DTC. The dashboard indicators are intended for driver notifications, NOT vehicle diagnostics.
- DTCs may be triggered as a result of the loss OR the repair process when electrical systems are disconnected during the restoration of the vehicle.
- The presence or absence of dashboard indicators/warning lights is NOT an acceptable method to determine if a post-repair diagnostic scan is necessary. ALL Nissan vehicles from 2008 forward MUST have a post-repair diagnostic scan for this reason.
