PINPOINT TEST H: THE SMART JUNCTION BOX (SJB) DOES NOT RESPOND TO THE SCAN TOOL
Normal Operation
The smart junction box (SJB) communicates with the scan tool through the medium speed controller area network (MS-CAN). Circuits VDB06
(GY/OG) (MS-CAN +) and VDB07 (VT/OG) (MS-CAN -) provide the network connection to the SJB. Voltage for the SJB is provided by circuit
SBB19 (BU/RD). Circuit GD116 (BK/VT) provides ground.
The SJB shares the MS-CAN with the following modules:
-
Accessory protocol interface module (APIM) (if equipped)
-
Audio control module (ACM)
-
Audio digital signal processing (DSP) module (if equipped)
-
Driver seat module (DSM) (if equipped)
-
Driver door module (DDM) (if equipped)
-
Dual climate control seat module (DCSM) (if equipped)
