B18070B2018-08-06. Service bulletin. EQUIPMENT; EQUIPMENT ADAPTIVE/MOBILITY. Service news article - If the On Demand Multi-Use Display? (ODMD) isn't responding to touch or is freezing up, the reason could be there's debris lodged in the gap between the touch screen and the bezel. Lodged debris contacting the screen can cause a false input, resulting in this issue. And since that gap widens and narrows with cabin temperature, this issue can be intermittent, especially in cold weather.
B18070C2018-07-30. Service bulletin. EQUIPMENT. Servicenews article - Until recently, Tech Line had only two categories for auto idle stop system issues. That made it hard for our engineering staff to understand what was specifically inhibiting the system. To help with this, Tech Line has added more categories to match what's listed in the service information. As a result, when calling them for an auto idle stop issue, you must now send a snapshot. Tech Line needs it for troubleshooting and won't be able to help unless you do.
