operating.
* Before measuring the resistance, leave the vehicle as is for at least 1 minute and do not operate the engine switch, any other
switches or the doors. If any doors need to be opened in order to check connectors, open the doors and leave them open.
HINT
* Operating the engine switch, any other switches or a door triggers related ECU and sensor communication on the CAN. This
communication will cause the resistance value to change.
* Even after DTCs are cleared, if a DTC is stored again after driving the vehicle for a while, the malfunction may be occurring
due to vibration of the vehicle. In such a case, wiggling the ECUs or wire harness while performing the inspection below may
help determine the cause of the malfunction.
PROCEDURE
1. CHECK CAN BUS WIRE
(a) Turn the engine switch off.
(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
(c) Disconnect the cable from the negative (-) battery terminal.
(d) Measure the resistance according to the value(s) in the table below.
Standard Resistance:

Result:
D -- CHECK FOR SHORT IN CAN BUS WIRES (POWER MANAGEMENT CONTROL ECU)
C -- CHECK FOR SHORT IN CAN MS BUS WIRE (POWER MANAGEMENT CONTROL ECU)
