Communication
Description
When a key is inserted into the ignition key cylinder but no communication
occurs between the key and
transponder key ecu, dtc b2796 is output. When a key is inserted into the
ignition key cylinder but a
communication error occurs between the key and transponder key ecu, dtc b ...
Check mode procedure
Hint:
Intelligent tester only:
compared to normal mode, check mode is more sensitive to
malfunctions. Therefore, check mode can detect the
malfunctions that cannot be detected by normal mode.
Notice:
All the stored dtcs and freeze frame data are erased if:
The ecm is changed from normal mo ...
Check for open circuit
For an open circuit in the wire harness in fig. 1,
Check the resistance or voltage, as described below.
Check the resistance.
Disconnect connectors a and c, and measure
the resistance between them.
Standard resistance (fig. 2)
Hint:
Measure the resistance while lightly s ...
