Abs light and anti skid light come on, and go off as normal when ignition is switched on, but a few seconds after starting the engine they come back on even if the car hasnt moved, There are no faults coming up on the plug in OBD, Anyone experienced this or have any thoughts. Any help would be greatly appreciated. Thank's.

Points to an ABS loom or sensor problem - however sensor failure usually highlighted once wheel rotation is detected by the system.
Check the battery voltage , ECU's require a minimum threshold of volts to function correctly

If its a j11 2014 onwards check the rear abs connectors wires are prone for breaking here right at the back of the connector

Nope the recall was for a rubbing brake hose so a braket got fitted to hold wheel arch liner away from brake hose

Your code scanner may not be capable of picking up all errors. Many are Nissan specific....a generic scanner cannot identify.

Thank's guys for your help. Got sorted....!!! The small pipe at the back of the engine from the exhaust manifold to the exhaust pressure sensor was blocked. Sooted up with carbon. I removed the pressure sensor and started the engine. Was getting no exhaust pressure/gas through the pipe to sensor. Used a drill and multi-core flexible wire cable to rod down and clear blockage. Not easily accessible, especially getting around the 90 deg bend on pipe, but after an hour and several clean attempts, got the pipe cleared. Started the engine again before fitting the pressure sensor and was getting a good flow through the pipe, could easily feel the pressure flow on my hand. Fitted the pressure sensor and all warning lights gone. Problem seems to be solved. Just don't understand why no fault messages/codes were coming up on OBD, or why the exhaust gas pressure was giving ABS faults on dash.....? Must be a Nissan software thing....? Again, thanks for your help, hope this helps out other's on the forum.

Exhaust Gas monitoring is a fundamental requirement for Engine Management. Errors from sensors in the exhaust system (at least 3 sensors) will prevent the ECU controlling the engine correctly. This may disable functions of the Body Control System...hence the ABS/Skid warnings.

There are a large number of DTCs related to the engine that a generic OBD scanner cannot resolve...they are Nissan specific.
