2001 Chevy Venture
3400 V6 cyl
ABS Light
codes = C1218, C1225, C1232
work done prior = In the past I cleaned the connectors on the exterior
of the vehicle which are located approximately under the driver's seat.
I think these are the wheel speed sensor connectors. They were
somewhat corroded, but this did not seem to correct the problem.
Work done to repair = In the past I cleaned the connectors on the
exterior of the vehicle which are located approximately under the driver's
seat. I think these are the wheel speed sensor connectors. They were
somewhat corroded, but this did not seem to correct the problem.
Tech = umm...anybody
question = What are some things I should try to troubleshoot what the
real issue is here? The codes are showing sensor problem and pump
problem which sounds to me like it is likely an electrical problem giving
false codes.
JK:
These codes do not seem related. The c1218 is a voltage problem between
the ABS control module (EBCM) and the pump motor / brake pressure
modulator valve (BPMV). This can be an internal fault in the BPMV. Some
electrical test would need to be done, which requires separating the two
components.
The other 2 codes are speed variations errors. Checking the connector
under the van is a great place to start. If there was some corrosion, it may
also be in body connector under the carpet. That half can have corrosion
and cause high resistance. Would suggest pulling up the carpet to check
the top half of the connector.
Sensor / hub bearings, or their related harness are common causes for
speed variation codes.

A few other Chevy questions.
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.
