POWER MIRROR CONTROL SYSTEM TERMINALS OF ECU


  1. CHECK MAIN BODY ECU (MULTIPLEX NETWORK BODY ECU) AND INSTRUMENT PANEL JUNCTION BLOCK ASSEMBLY (w/ Retract Mirror)

    A005QBPN22

    1. Remove the main body ECU (multiplex network body ECU) from the instrument panel junction block assembly.


    2. Reconnect the instrument panel junction block assembly connectors.

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

      Tech Tips

      Measure the values on the wire harness side with the connector disconnected.

      Terminal No. (Symbol) Wiring Color Terminal Description Condition Specified Condition
      MB-11 (GND1) - Body ground - Ground Always Below 1 Ω
      MB-31 (BECU) - Body ground - Battery power supply Always 11 to 14 V
      MB-30 (ACC) - Body ground - Ignition power supply (ACC signal) Ignition switch ACC 11 to 14 V
      MB-30 (ACC) - Body ground - Ignition power supply (ACC signal) Ignition switch off Below 1 V
      MB-32 (IG) - Body ground - Ignition power supply (IG signal) Ignition switch ON 11 to 14 V
      MB-32 (IG) - Body ground - Ignition power supply (IG signal) Ignition switch off Below 1 V

    4. Install the main body ECU (multiplex network body ECU) to instrument panel junction block assembly.


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