Before servicing, electric motor switch OFF, disconnect 12V battery negative terminal and wait for 3 minutes or more (discharges electricity held
in the additional power supply circuit of the air bag diagnosis sensor unit).



Battery posts, terminals and related accessories contain lead and lead compounds. WASH HANDS AFTER HANDLING.



Before disconnecting the air bag sensor unit harness connector, be sure to disconnect each harness connector of the air bag modules, seat belt
pre-tensioners and lap pre-tensioner to prevent air bag deployment by static electricity and seat belt pre-tensioner operation.



U2117-87 CAN comm err (DCM)
DTC Logic

DTC Logic

CAN (Controller Area Network) is a serial communication line for real time applications. It is an on-vehicle multiplex communication line with high data communication speed and excellent error detection ability. Modern vehicle is equipped with many electronic control unit, and each control unit shares information and links with other control units during operation (not independent). In CAN communication, control units are connected with 2 communication lines (CAN H-line, CAN L-line) allowing a high rate of information transmission with less wiring. Each control unit transmits/receives data but
selectively reads required data only.
