When the switch is in the ON  position, the current level in sensor A must be in the range of 1.6-6.4 mA and the current level in sensor B must be in the range of 12.8-20.1 mA.

Use the VCT2000 (or appropriate scan tool) to read off the current level.

Replace the switch if any of the current levels are outside the listed ranges.

• Switch off the ignition. Wait 10 seconds
• Set the switch to the OFF  position
