# Service bulletin MC130121

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

Mainly sporadic, isolated but also permanent faults occur in the throttle grip sensor, throttle valve,crankshaft signal, camshaft signal, transmission signal, fuel pressure sensor, gear\-lever sensor \(GearShift Assistant\), oxygen sensor and switching cam. These can result in functional impairments andmalfunctions, fault messages and fault memory entries. Besides isolated defective components, the sporadic faults are often mainly caused by contactproblems and increased contact resistances. These can generally occur along the entire signal pathof the respective affected component, but especially at plug connections. In this context, the plugconnection to the engine control unit has emerged as the main focus of the fault. Analyses of defective parts showed that in many cases the passivation \(a production coating\) of thepins at the plug\-in contact \(plug connection\) of the engine control unit can result in correspondingfaults. A service solution for cleaning the pins has been created which can considerably improvecontact if implemented correctly. In most cases, this means that exchanging expensive componentslike the DME or the wiring harness can be avoided.
