Problem with my 2004 Pontiac Montana
I am a law student in Canada, working on a small claims file for a client with respect to a
2004 Pontiac Montana she purchased and has had several problems with. A few days
after it was purchased she took it to a mechanic and the following codes came up:
C1223 and C1225. It is my understanding that these codes are related to the ABS
system. My question is, should/would these problems have caused the ABS light on the
dashboard to go on?
JK:
Yes, these codes would turn on the ABS indicator on the dash. That is, when the fault
occurs.
These 2 codes have different criteria that must be met when the fault occurs for the
light to come on and the code to set.
If the faults happened, and the light came on, but then the there was a specific number
of drive cycles without the fault, then the light would go out, the code would remain in
the modules memory (history data) for some time, then after more time, it would be
erased.
Another scenario is that the customer is feeling a problem with the ABS system, as it
seems to buzz or activate while turning or driving slowly. If it happens for a period of
time shorter than the requirement for the light, it may not set a light.
Thanks and hope we helped !

ABS / Anti lock brake warning.
The anti-lock braking system (ABS) uses several sensors, motors, and a computer in conjunction with the normal braking
system.
The ABS regulates the brake pressure in order to reduce wheel lock-ups. Reduced wheel lock-ups improve the driver's
control of the vehicle during braking.
Improved stability and steering enable greater control of the vehicle in the case of an abrupt stop.
The ABS operation is available from 5 km/h (3 mph) to the maximum vehicle speed.
A warning light means a problem was detected, and the system needs to be scanned for codes in order find out the area the
fault is in. With the light on, ABS operation is not present, but normal braking is.
The Traction Control System is controlled by the ABS system.
