TERMINALS OF ECU
1. CHECK TRANSPONDER KEY AMPLIFIER
(a) Disconnect the E5 amplifier connector.
(b) Measure the resistance of the wire harness side
connector.
If the result is not as specified, there may be a
malfunction in the wire harness.
(c) Reconnect the E5 amplifier connector.
(d) Measure the resistance and voltage of the
connector.
If the result is not as specified, there may be a
malfunction in the amplifier.
(e) Using an oscilloscope, check the waveform 1.

DESCRIPTION
This DTC is output if the transponder key ECU does not detect that the unlock warning switch is ON even
when the ignition switch is ON. Under normal conditions, the unlock warning switch is ON when the
ignition switch is ON.

INSPECTION PROCEDURE
(a) Connect the intelligent tester (with CAN VIM) to the
DLC3.
(b) Turn the ignition switch ON with a key that cannot start
the engine.
(c) On the intelligent tester, enter the following menus:

DESCRIPTION
The transponder key coil receives key code signals from the transponder chip in the key grip. The coil
built into the transponder key amplifier amplifies the key code signals and outputs the signal to the
transponder key ECU.
