  1. CHECK NAVIGATION RECEIVER ASSEMBLY

    A01SJVQN01

    1. Disconnect the G113 and G115 navigation receiver assembly connectors.

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

      Terminal No. (Symbol) Wiring Color Terminal Description Condition Specified Condition
      G113-1 (IG) - Body ground G - Body ground Power source of IG Ignition switch off Below 1 V
      Ignition switch ON 11 to 14 V
      G115-3 (ACC1) - Body ground GR - Body ground Power source of ACC Ignition switch off Below 1 V
      Ignition switch ACC 11 to 14 V
      G115-4 (+B1) - Body ground SB - Body ground Battery Always 11 to 14 V
      G115-7 (GND1) - Body ground BR - Body ground Ground Always Below 1 Ω

    3. Reconnect the G113 and G115 navigation receiver assembly connectors.

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