1. CHECK ENVIRONMENTAL CONDITION. 

   Check if any external devices which emit strong electromagnetic waves and noises, such as a radio antenna, is installed inside the vehicle.

   Is an external device installed?

   • Yes  : Remove the external device to check the operation. If the fault is not fixed: Go to  2.
   • No  : Go to  2.
2. CHECK CONNECTOR CONNECTION. 

   Check that the connector is connected to the unit.

   Is the connector connected?

   • Yes  : Go to  3.
   • No  : Connect the connector.
3. CHECK CONNECTOR. 

   Check for poor contact of connectors or terminals.

   Is the connector OK?

   • Yes  : Go to  4.
   • No  : Repair or replace the harness.
4. CHECK POWER SUPPLY VOLTAGE. 
   1. Turn the ignition switch to ACC.
   2. Using a tester, measure the voltage between connector and chassis ground.
      NOTE: Turn the electrical parts to OFF.

      Connector & terminal 

      Model without power amplifier 

      (i85) No. 4 (+) - Chassis ground (-):

      Model with power amplifier 

      (i35) No. 4 (+) - Chassis ground (-):

      Is the voltage 12 V or more?

      • Yes  : Go to  8.
      • No  : Go to  5.
5. CHECK OPEN CIRCUIT IN HARNESS (POWER SUPPLY). 

   Using the tester, measure the resistance between connector and chassis ground while shaking the harness.

   Connector & terminal 

   (i85) No. 4 - Chassis ground:

   Is the resistance 1 Ω or less?

   • Yes  : Go to  6.
   • No  : Repair or replace the open circuit of harness.
6. CHECK OPEN CIRCUIT IN HARNESS (GROUND). 

   Using the tester, measure the resistance between connector and chassis ground while shaking the harness.

   Connector & terminal 

   (i85) No. 7 - Chassis ground:

   Is the resistance 1 Ω or less?

   • Yes  : Go to  7.
   • No  : Repair or replace the open circuit of harness.
7. CHECK BATTERY. 

   Check the battery. Ref. to STARTING/CHARGING SYSTEMS(H4DO)>Battery>INSPECTION .

   Is the battery OK?

   • Yes  : Go to  8.
   • No  : Replace the unit. Ref. to ENTERTAINMENT>Audio .
8. CHECK UNIT OPERATION. 
   1. Connect all connectors.
   2. Turn the ignition switch to ACC and the power supply switch of the unit to ON.

   Is the reset eliminated?

   • Yes  : Currently no failure is found.
   • No  : Replace the unit. Ref. to ENTERTAINMENT>Audio .
