Fault Detection

The Air Conditioning Programmer (ACM) and Climate Control Panel (CCP) contains Self Diagnostics that, when accessed either by on-boards or with a scan tool, are designed to identify the source of any system malfunction as specifically as possible, including whether or not the malfunction is current or the non-current (history) type.

On-boards only allow the viewing and clearing of the DTC's. Any tests or overrides must be performed with the Scan Tool.
