Diagnosis And Testing - Right MULTIFUNCTION Switch

WARNING: This page is about a different car, the 2017 Jeep Cherokee. However, it is still accessible from the selected car via links, so may be relevant.

The hard wired inputs and outputs of the Steering Column Control Module (SCCM) may be diagnosed using conventional diagnostic tools and procedures. Refer to the appropriate wiring information. However, conventional diagnostic methods will not prove conclusive in the diagnosis of the right multifunction switch or the electronic controls and communication between other modules and devices that provide some features of the wiper and washer system. The most reliable, efficient and accurate means to diagnose the right multifunction switch, the SCCM microcontroller or the electronic controls and communication related to right multifunction switch operation requires the use of a diagnostic scan tool. Refer to the appropriate diagnostic information. Refer to MODULE, STEERING COLUMN CONTROL (SCCM), DIAGNOSIS AND TESTING .
