Accessory Protocol Interface Module (APIM) Programming

APIM programming is a process that updates the APIM Consumer Interface Processor (CIP) and Vehicle Interface Processor (VIP) software. The VIP programming updates the calibration files in the portion of the APIM which interfaces with the Controller Area Network (CAN). The CIP programming updates calibration files in the portion of the APIM that interfaces with mobile phones and other customer devices.

APIM programming uses the VCM to read and program the VIP software through the Data Link Connector (DLC). A web-based On-Line Automotive Service Information System (OASIS) application is used to read and program the CIP software via a Universal Serial Bus (USB) cable between the scan tool and vehicle USB port. Both the VCM and OASIS application must be running on the scan tool during APIM programming. To carry out APIM programming, refer to ACCESSORY PROTOCOL INTERFACE MODULE (APIM) PROGRAMMING . To carry out APIM software level check, refer to INFORMATION AND ENTERTAINMENT SYSTEMS article.
