DIAGNOSTIC PROCEDURE

Step Check Yes No
1 CHECK X MODE SWITCH. 
  1. Turn the ignition switch to OFF.
  2. Disconnect the connector from the combination meter.
  3. Measure the resistance when the X mode switch is operated.

    Connector & terminal 

    (i10) No. 37 - Chassis ground: 

 Does the resistance change as below?
1 MΩ or more → less than 10 Ω		 Go to step 5  . Go to step 2  .
2 CHECK HARNESS BETWEEN COMBINATION METER AND X MODE SWITCH CONNECTOR. 
Measure the resistance of harness between combination meter and X mode switch connector.
Connector & terminal 
(i10) No. 37 - (i70) No. 1: 		 Is the resistance less than 10 Ω? Go to step 3  . Repair the harness and connector.
NOTE: In this case, repair the following item:
  • Open circuit in harness between combination meter and X mode switch connector
  • Poor contact of connector
3 CHECK HARNESS BETWEEN COMBINATION METER AND X MODE SWITCH CONNECTOR. 
Measure the resistance of harness between X mode switch connector and chassis ground.
Connector & terminal 
(i70) No. 1 - Chassis ground: 		 Is the resistance 1 MΩ or more? Go to step 4  . Repair the short circuit to ground in harness between combination meter and X mode switch connector.
4 CHECK HARNESS BETWEEN X MODE SWITCH CONNECTOR AND CHASSIS GROUND. 
Measure the resistance between combination meter and chassis ground.
Connector & terminal 
(i70) No. 4 - Chassis ground: 		 Is the resistance less than 10 Ω? Repair the poor contact of X mode switch connector. Replace the X mode switch if faulty. < Ref. to X MODE SWITCH . > < Ref. to X MODE SWITCH . > Repair the harness and connector.
NOTE: In this case, repair the following item:
  • Open circuit in harness between X mode switch connector and chassis ground
  • Poor contact of joint connector
5 RECHECK FAULT. 
  1. Connect all connectors.
  2. Switch to X mode.
 Is there any fault? Repair the poor contact of combination meter. Replace the meter case assembly if defective. The circuit has returned to a normal condition at this time. Reproduce the failure, and then perform the diagnosis again.
NOTE: In this case, temporary poor contact of connector, temporary open or short circuit of harness may be the cause.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
