# Service campaign MC610125

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

## NHTSA's summary

The DME sends at each engine start the downtime duration since the last time the engine was in use as a signal to decide between cold or warm \(normal\) start mode. Note: During a warm \(normal\) start, the catalyzer is not pre\-heated due to the short engine downtime. Due to a programming error, the calculated engine downtime duration is always 0 minutes. Therefore, the engine will always start in warm \(normal\) start mode \(independently of the real engine downtime duration\). In the case where the cold start mode would be required the bike used warm \(normal\) start mode instead, resulting in a lack of the catalytic converter pre\-heating, leading to increased emissions during the warm\-up period of the engine.
