ON-BOARD DIAGNOSTIC SYSTEM ACTIVE COMMAND MODES FUNCTION (ABS, DYNAMIC STABILITY
CONTROL)
E5U040243750N04
• The active command modes function is used for optionally selecting active command modes items of input/
output parts preset in the ABS HU/CM or DSC HU/CM, and to operate them regardless of CM control.
• To protect the hydraulic unit interior, operate output related parts for only 10 s or less when using the active
command modes function.

ON-BOARD DIAGNOSTIC SYSTEM EXTERNAL TESTER COMMUNICATION FUNCTION (ABS, DYNAMIC
STABILITY CONTROL)
E5U040243750N05
• 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 CAN_H and CAN_L
terminals (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.

DLC-2 CONSTRUCTION
E5U040243750N06
• A connector (DLC-2) conforming to International Organization for Standardization (ISO) standards has been
added.
• Shape and terminal arrangement as stipulated by the ISO 15031-3 (SAE J1962) international standard has
been adopted for this connector. The connector has a 16-pin construction that includes the CAN_H (HS),
CAN_L (HS), GND1, GND2 and B+ terminals.
