VSA Activation Indicator Does Not Come On
Does the brake system indica-
tor come on?
Check the VSA activation indica-
tor:
1. Turn the ignition switch OFF.
2. Check the VSA activation indi-
cator bulb in the gauge assem-
bly.
Is the bulb OK?
Check the VSA control unit:
1. Disconnect the VSA control
unit 42P connector.
2. Turn the ignition switch ON (II).
3. Connect the VSA control unit
42P connector terminal No. 7
and body ground with a
jumper wire.
Does the VSA activation
indicator come on?
Check the gauge assembly:
Connect the gauge assembly 22P
connector terminal No. 2 and
body ground with a jumper wire.
Does the VSA activation
indicator come ON?
Repair open in the wire between
the gauge assembly and the VSA
control unit.
Gauge relay stuck OFF.
Blown METER (15 A) fuse in the
under-hood fuse/relay box.
Blown METER (7.5 A) fuse in
the under-dash fuse/relay box.
Repair open in the wire between
the METER (15 A) fuse and the
gauge assembly.
Repair open in the wire between
the METER (7.5 A) fuse and body
ground.
Replace the under-hood fuse/
relay box or under-dash fuse/
relay box. (Open circuit inside
the
box.)
Replace the VSA activation indi-
cator bulb.

Check for a short to body ground
in the INFO circuit:
1. Disconnect the VSA control
unit 42P connector.
2. Turn the ignition switch ON (II).

DTC 11, 13, 15, 17: Wheel Sensor (Open/Short to Body Ground/Short to Power)
Check for a short to power in the
wheel sensor circuit:
1. Disconnect the VSA control
unit 42P connector.
2. Start the engine.
3. Measure the voltage between
the VSA control unit 42P con-
nector appropriate wheel sen-
sor (+) circuit terminal and
body ground (see table).

VSA CONTROL UNIT 42P CONNECTOR
Is there battery voltage?
Repair short to power in the {+)
or (-) circuit wire between the
VSA control unit and appropriate
wheel sensor.
Wire side of female terminals
Check for a short to body ground
in the wheel sensor circuit:
1. Turn the ignition switch OFF.
2. Check for continuity between
the VSA control unit 42P con-
nector appropriate wheel sen-
sor (+) circuit terminal and
body ground (see table).
Is there continuity?
Repair short to body ground in
the (+) or (-) circuit wire between
the VSA control unit and the
appropriate wheel sensor.
Replace the appropriate wheel
sensor.
Check for an open in the wheel
sensor circuit:
Measure the resistance between
the VSA control unit 42P connector
appropriate wheel sensor (+) and
(-) circuit terminals (see table).
Is the resistance between
450 - 2,000 at 68°F?
• Repair open in the (+) or (-) cir-
cuit wire between the VSA con-
trol unit and the appropriate
wheel sensor.
• Replace the appropriate wheel
sensor.
Check for loose terminals in the
VSA control unit 42P connector.
If necessary, substitute a known-
good VSA modulator-control
