TERMINALS OF ECU

NOTICE:

  • When performing an inspection, make sure that "ACC Customize" is set to "ON" using the multi-display.

    Click here 2023 - 2025 MY Corolla Corolla Hatchback Corolla HV GR Corolla [11/2022 -        ]; THEFT DETERRENT / KEYLESS ENTRY: SMART KEY SYSTEM (for Entry Function): CUSTOMIZE PARAMETERS

  • When "ACC Customize" is set to "ON" (ACC supply power enabled), the certification ECU (smart key ECU assembly) controls the ACC relay on and off. When "ACC Customize" is set to "OFF" (ACC supply power disabled), the certification ECU (smart key ECU assembly) and radio and display receiver assembly control the ACC relay on and off.

    Therefore, inspection conditions and results may differ depending on whether "ACC customize" is set to ON or OFF when inspecting ACC related terminals.

CHECK CERTIFICATION ECU (SMART KEY ECU ASSEMBLY)

(a) Disconnect the O175 and I167 certification ECU (smart key ECU assembly) connectors.

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

  • *1: for HV Model
  • *2: for Gasoline Model
  • *3: In order to prevent the vehicle auxiliary 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 auxiliary 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 O175 and I167 certification ECU (smart key ECU assembly) connectors.

(d) Measure the voltage and check for pulses according to the value(s) in the table below.
