Inspection procedure
Notice:
- Turn the ignition switch off before measuring the resistances
of the main wire and the branch
wire.
- After the ignition switch is turned off, check that the key
reminder warning system and light
reminder warning system are not in operation.
- Before measuring the resistance, leave the vehicle for at least
1 minute and do not operate the
ignition switch, any switches or doors. If doors need to be opened in order
to check
connectors, open the doors and leave them open.
Hint:
Operating the ignition switch, any switches or any doors triggers related ecu
and sensor communication
with the can, which causes resistance variation.
- Check can bus line disconnection (abs and traction actuator branch
wire)

- Disconnect the a19 abs and traction actuator (skid
control ecu) connector.
- Measure the resistance of the wire harness side
connector.

Communication malfunction no. 1
Description
This dtc is output when a communication error occurs between the transponder
key amplifier and
transponder key ecu. Some possible reasons for the communication error are: 1) 2
or more ignition keys
are positioned too close together, or 2) noise is occurring in the communicatio ...
