Arrow 11001EM A.R.D. Alert Remover Device – Euro 5+ Exhaust Engine Fault Light

The A.R.D. Arrow 11001EM (Alert Remover Device) is an electronic device that switches off the engine warning light when the ECU detects an error from the post-catalytic lambda sensor after installing a racing exhaust or a de-cat header. It connects to the OBD diagnostic port using the included splitter in a plug-and-play fashion, and can be removed when needed. Product code 11001EM.

Who it is perfect for

The A.R.D. is the part needed for anyone who has just installed a racing exhaust or a header without a catalytic converter on a Euro 5+ motorcycle and finds themselves with an orange warning light on the dashboard. It costs a fraction of an ECU reflash, can be installed in a few minutes without special tools, and can be removed before servicing, leaving the motorcycle exactly as it was delivered by the dealer. Suitable for workshops, tuners, and private individuals who use their motorcycle on the track.

Frequently asked questions

What is the Arrow 11001EM A.R.D. for?
It is used to turn off the engine fault light that comes on when the ECU reads an error from the post-catalytic lambda sensor, typically after installing a racing exhaust or a header that eliminates the original catalytic converter. It only acts on that specific warning, nothing else.

How is it installed?
It connects to the motorcycle's OBD diagnostic port using the included splitter cable: there is no need to program it or have the ECU remapped, and no cables need to be cut. The operation takes a few minutes and is completely reversible, as the device can be detached without leaving any trace.

Is it suitable for my motorcycle?
The manufacturer's catalogue lists it for 74 Euro 5+ applications with dual lambda sensors, from Aprilia to Yamaha, including BMW, CF Moto, Ducati, Harley-Davidson, Honda, Husqvarna, Kawasaki, Kove, KTM, Piaggio Vespa, Suzuki, Triumph, and Voge. The complete list with years is in the table above.

Does it make my racing exhaust street-legal?
No, and it must be clearly stated: the A.R.D. acts on the error notification, not on emissions. A non-homologated exhaust remains non-homologated and must only be used on the track; this device only serves to keep the warning light off on the dashboard.

Does it consume power or drain the battery?
No. When the ignition is off, consumption is zero: the device automatically deactivates after the engine stops. You can leave it connected even if the motorcycle is parked for a long time without worrying about the battery.

Does it change the engine's performance?
No: it does not affect the mapping and does not change operating parameters. It only intervenes in the management of the error message linked to the lambda sensor, allowing the ECU to do everything else exactly as before.
