General Troubleshooting Information

This system has four indicators:
• ABS indicator (A)
• Brake system indicator (B)
• VSA indicator (C)
• VSA activation indicator (D)
When the system is OK, each indicator comes on for
about 2 seconds after turning the ignition switch to
ON (II), then goes off.
When the system detects a problem, a DTC is set and,
depending upon the failure, the VSA modulator-control
unit determines which indicator(s) are turned on. If the
problem goes away (system returns to normal), the
indicator(s) are controlled in the following way
depending upon the DTC that is set:
• The indicator(s) come on and stay on when the
ignition switch is ON (II).
• The indicator(s) automatically go off.
• The indicator(s) go off after the vehicle is driven.
The ABS indicator comes on when the ABS function is
lost. The brakes still work like a conventional system.
The brake system indicator comes on when the EBD
function is lost, the parking brake is applied, and/or the
brake fluid level is low.
NOTE: If two or more wheel speed sensors fail, the
brake system indicator comes on.
The VSA indicator comes on when the VSA function is
lost.
The VSA activation indicator blinks when the VSA
function is activating. The VSA activation indicator
comes on and stays on when the VSA is turned OFF by
using the VSA OFF switch, or when the VSA function is
lost.
