Check Power Supply And Ground Circuit

Step Check Yes No
1 CHECK POWER SUPPLY FOR COMBINATION METER. 
  1. Remove the combination meter.
  2. Measure the voltage between combination meter connector and chassis ground.

    Connector & terminal 

    (i10) No. 20 (+) - Chassis ground (-): 

Is the voltage 10 V or more? Go to step 2.  Check the harness for open or short between the fuse and combination meter.
2 CHECK POWER SUPPLY FOR COMBINATION METER. 
  1. Turn the ignition switch to ON.
  2. Measure the voltage between combination meter connector and chassis ground.

    Connector & terminal 

    (i10) No. 19 (+) - Chassis ground (-): 

Is the voltage 10 V or more? Go to step 3.  Check the harness for open or short between the ignition switch and combination meter.
3 CHECK GROUND CIRCUIT OF COMBINATION METER. 
  1. Turn the ignition switch to OFF.
  2. Measure the resistance between combination meter connector and chassis ground.

    Connector & terminal 

    (i10) No. 39 - Chassis ground: 

Is the resistance less than 10 Ω? Replace the meter case assembly. Repair or replace the harness.
