NO-Go to step 2.
2. Turn the ignition switch OFF, then turn it ON (II) again.
Does the brake system indicator come on?
YES-Go to step 3.
NO-Repair open in the indicator power source circuit.
^ Blown TURN & HAZARD LIGHT (7.5A) fuse.
^ Open in the wire between the TURN & HAZARD LIGHT (7.5A) fuse and gauge assembly.
^ Open circuit inside the fuse box.
^ Open on the printed circuit board in the gauge assembly.
3. Turn the ignition switch OFF.
4. Disconnect VSA control unit connector B (16P).
5. Turn the ignition switch ON (II).
Does the VSA system indicator come on?
YES-Check for loose terminals in the VSA control unit connectors. If necessary, substitute a known good VSA control unit, and recheck.
