Test Mode Procedure
Diagnosis SystemAntenna Coil Open / Short (B2784)
DESCRIPTION
The transponder key coil is built into the transponder key amplifier and receives
a key code signal from the transponder chip in the key. This signal is amplified
by the amplifier, then it is output to the transponder key ECU assembly.

DESCRIPTION
These DTCs are stored if a key that does not have a transponder chip is inserted
into the ignition key cylinder or if communication between the key and the transponder
key ECU assembly is impossible.
