and reinstall the fuse if it is OK.

Is the fuse OK?

Check for an open in the +B FSR
circuit:

1. Disconnect the VSA control

unit 42P connector.

2. Measure the voltage between

terminal No. 6 and body
ground.

Is there battery voltage?

Check for an open in the GND cir-
cuit:

1. Turn the ignition switch OFF.

2. Check for continuity between

the VSA control unit 42P con-
