Scan Tool Data Display
The scan tool has the capability of displaying various HVAC information. This information assists in determining whether or not the Electronic Climate Control
(ECC) module is sending or receiving the proper data to various systems/components. The ECC module uses data received from other systems in order to carry out some functions. Therefore, it the ECC module receives the incorrect data from another system, the HVAC system may function improperly. Use the scan tool in order to review the data that interacts with the HVAC system.
