a.

Disconnect the I1 certification ECU (smart key ECU assembly) connector.


b.

Measure the voltage and resistance according to the value(s) in the table below.

Tester Connection Terminal Description Condition Specified Condition Related Data List Item
I1-18 (E) - Body ground Ground Always Below 1 Ω -
I1-3 (+B) - I1-18 (E) Power supply Always 11 to 14 V -
I1-17 (CUTB) - I1-18 (E) Dark current cut pin* Always 11 to 14 V -

*: In order to prevent the vehicle battery from being depleted when the vehicle is shipped long distances, a fuse that cuts unnecessary electrical load while the vehicle is being shipped is installed in the circuit. If the fuse is removed, the circuit becomes open. If the fuse that is between the vehicle battery and terminal CUTB is removed and the circuit is open, the certification ECU (smart key ECU assembly) changes to a certain control mode (example: the transmission of radio waves every 0.25 seconds, which form the detection area, stops).



c.

Reconnect the I1 certification ECU (smart key ECU assembly) connector.


d.
