Component Location
General Description

Transponder is located near the Key knob and communicates while ignition ON translates encrypted PIN data back and forth.

Reference)

1.

Transponder does not need a battery, only receives energy from the vehicle.

2.

Transponder is all in one with the Key. Therefore, transponder cannot be removed or replaced and is semi-permanent unless damaged by induced shock.

DTC Description

If ICU detects invalid transponder data, the DTC will set.

DTC Detecting Condition

Item

Detecting Condition

Possible Cause

DTC Strategy

•

Data status receiving from transponder

1.

Faulty Transponder

Threshold value

•

When the coil supplies energy to the transponder which in turn accumulates energy in the condenser, ICU transmits the data(40bit) to the transponder

If ECM/PCM detects difference between data receiving from transponder and predetermined value, DTC will set

Detecting time

•

1 time

DTC Erasing

Condition

•

Without a fault or using a GDS
