Genera

l Motors provides additional information along with the DTCs:

❒ Curre

nt - A current DTC indicates that a failure is currently present. A

current code may have just occurred or may have been present over

time.

❒

History -

A DTC with a History designation is one that has been detected

by the anti-lock brake control module over a span of time. It is a current

failure that has been present long enough to be stored in long-term

memory.

❒ CURR/H

IST - A CURR/HIST DTC indicates that a failure is both current

and historical as defined above.

❒

Intermittent - An intermittent status indicates that the DTC has appeared

intermittently since the anti-lock brake control module was reset. (Control

modules are reset by mechanics after a repair has been completed.)

❒

MIL Code - Indicates

that the ABS Computer is reporting that the ABS

Malfunction Indicator Light is on. If MIL Code is displayed by the Tool, but

the vehicle dashboard does not display the ABS MIL, then you have a

potential problem with the circuit that controls the ABS MIL, the bulb

itself, a fuse, or the electrical system.

This code indicates that you currently

have a problem with the Left Front

Wheel Speed Sensor Circuit and that

the problem is illuminating the ABS

malfunction indicator lamp (MIL) on

the dashboard.

This code indicates that you have had

a problem with the Pump Motor Circuit

long enough to be stored in long-term

memory and that the problem is illumi-

nating the ABS malfunction indicator

lamp (MIL) on the dashboard. ABS

systems rely on a pump to regulate

brake fluid distribution.
