ON-BOARD DIAGNOSTIC SYSTEM EXTERNAL TESTER COMMUNICATION FUNCTION (ABS, DYNAMIC
STABILITY CONTROL)
CHU040243000S05
• The external tester communication function enables communication of diagnostic data (DTC read-outs, input/
output signal read-outs, and operation of input/output parts) between the ABS HU/CM or the DSC HU/CM and
an external tester.
Connections and Communication Contents
Serial communication
• Serial communication (two-way communication) allows for multiple data to be sent and received instantly along
the same line.
• By connecting the WDS or equivalent to the DLC-2, diagnostic data can be sent and received between the
WDS or equivalent and the ABS HU/CM or DSC HU/CM using the KLN terminal (within the DLC-2).
• The ABS HU/CM or DSC HU/CM receives the command signals of the malfunction detection function, PID/data
monitor function, and the active command modes function from the WDS or equivalent, and sends DTCs and
data regarding the operating condition and status of each input/output part to the WDS or equivalent.
