Inspection Procedure

1. Connect the intelligent tester to DLC3.
2. Start the engine and turn the tester on.
3. Enter the following menus: DIAGNOSIS / OBD/MOBD / E-ACM / DATA LIST.
4. Read the G SENS VOL (1X) value.

   Standard voltage: 

   The voltage changes within the range of 0.11 to 4.46 V. 

NG: Go to step   3 

OK: Go to Next Step 

1. Connect the intelligent tester to DLC3.
