The ISO 9141 standard refers to the communication protocol used by DaimlerChrysler, Honda, and Toyota. This protocol has been used since 1996. The serial data line is the means by which the microprocessor-controlled modules that are connected to it communicate with each other. ...
That is not an error code. That is the OBD type of communication protocol. or standard. To read the OBD codes you must have a scanner that is capable of using this protocol to connect to the ecu.
KWP2000 (Keyword Protocol 2000) is not a trouble code but rather is the name given to a type of communications protocol that is used for on-board vehicle diagnostics systems. Auto diagnostic tools and programmers use Keyword Protocol 2000 to read and transfer data to your vehicle's electronic control unit, or ECU.

Where are you coming up with this ?
ISO 9141 and KWP 2000 this is a communication protacoll. when the scan tool is plug into the OBD port it uses a set amount of communication dialog to communicate with the ECM, Majority of time when a scan tool can not communicate with the vehicles ECM ,
The scan tool your using is generic ISO 9141 is used as the protocal. Its not a code. kwp2000 is not shown. Try and use it on manufacture specific or try and get any freeze frame codes and reply or repost. ( Don't forget to turn ignition key to the run position when trying to retrieve codes.)
This is a fault relating to an emission's control device called a Nitrous Oxide Trap. As on petrol engines there is a catalytic convertor, clean burning diesel engines need to remove the nitrogen gas from the exhaust gasses. Like any filter (even catalytic convertors), they can only absorb so much before they are full and need to be replaced. NOx Trap is relatively new technology.
ISO9141 is not a fault code- it refers to the communication system that your vehicle uses to relay info to and from its different computer boxes. Also a relatively new system, it is a CAN communications network that can transfer info and receive simultaneously, hence speeding up response times. This technology is critical in safety specific items such as ABS braking and Airbags as the faster you can get the unit to respond, the more efficient the system is.
