Use a tester with open terminal voltage of 7, turn the ignition switch OFF and disconnect the battery cable from negative terminal when, solder the repaired area and wrap tape around soldered area, a fray of twisted lines must be within 110 mm (4.
Bypass connection is never allowed repaired area, bypass connection may cause CAN communication error, spliced wire becomes separated and characteristics twisted, replace the applicable harness as an assembly if error is detected on the shield lines CAN communication line.
CAN COMMUNICATION SYSTEM : System Description, cAN (Controller Area Network) is a serial communication line for real time application, control units during operation (not independent), 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, diag on CAN” is a diagnosis method which uses the CAN communication line communication between, the control unit diagnostic tool, dIAG ON CAN : System Diagram.
For communications with the diagnostic tool, cAN communication line between splice control unit, a point connecting a branch line with main line, circuit connected across the CAN communication system.
CAN communication signal is not transmitted or received between units for 2 seconds more, cAN communication line open (CAN-H, CAN-L, both), cAN communication line short (ground, between CAN communication lines, other harnesses), error of CAN communication control circuit of the unit connected CAN communication line.
WHEN DTC OF CAN COMMUNICATION IS INDICATED EVEN THOUGH CAN COMMUNICATION, removal/installation of parts: Error may be detected when removing and installing CAN communication unit, and related parts while turning the ignition switch ON, fuse blown out (removed): CAN communication of unit may cease.
Voltage drop: Error may be detected if voltage drops due to discharged battery when turning ignition, switch ON (Depending on the control unit which carries out CAN communication), error may be detected if the power supply circuit of the control unit, which carries out CAN communication, malfunctions (Depending on the control unit which carries out CAN communication).
Error may be detected if reprogramming not completed normally, cAN communication system is normal if DTC of CAN communication indicated SELF-DIAG, rESULTS of CONSULT under the above conditions.
