DTC Examples
Below are several DTC examples.
✓
General Motors provides additional information along with the DTCs:
❒
Current - 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/HIST - 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.
