- Summary
- PRODUCT SUPPORT PROGRAM FOR REWORKING THE AIR CONTROL VALVE (ACV) CONNECTOR ON CERTAIN CT660 ON HIGHWAY TRUCKS - Some ACV connectors were produced with plugs installed backwards in empty connector cavities. This could permit water intrusion, which could short the terminals. This may lead to ACV failure or EGR cooler plugging. This repair will involve reinstalling the plugs in the correct orientation to ensure the connector is tightly sealed.
