4. Verify that there is no continuity between the coupler component terminals B19 and GND or B20 and GND.











- If there is continuity, inspect the coupler component.
- If the coupler component is normal, perform an off-vehicle inspection of VSS.

NOTE:
- Inspect with a tester that can indicate more than 10 megohms and confirm that the value is more than 1 megohm.

5. Verify that there is continuity between coupler component terminals B19 and B20.











- If there is no continuity, inspect the coupler component.
- If the coupler component is normal, replace the VSS. Vehicle Speed Sensor (VSS) Removal/Installation [AW6A-EL]

Off-Vehicle Inspection

1. Connect the VSS terminal 2 to the battery positive terminal, connect the battery negative terminal to VSS terminal 1 through an ammeter set to a resistance of 100 ohm.






2. Measure the current while waving a magnet back and forth over the top of the VSS (less than 5 mm {0.197 in}).






- If there is any malfunction, replace the VSS. Vehicle Speed Sensor (VSS) Removal/Installation [AW6A-EL]
