    Connector & terminal 

    (i84) No. 33 - Chassis ground: 

 Does the security indicator light illuminate? Check the body integrated unit. < Ref. to BASIC DIAGNOSTIC PROCEDURE . > Go to step 2. 
2 CHECK POWER SUPPLY FOR SECURITY INDICATOR LIGHT.

  2. Measure the voltage between the combination meter harness connector terminal and chassis ground.

    Connector & terminal 

    (i10) No. 1, 2 (+) - Chassis ground (-): 

 Is the voltage more than 10 V? Go to step 3.  Check the harness for open or short circuits between combination meter and fuse.
3 CHECK SECURITY INDICATOR LIGHT CIRCUIT.
