2001 Chevy Venture ABS Codes C1218, C1225 And C1232

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. 2001 Chevy Venture. ABS Light. Codes = C1218, C1225, C1232. 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. I think these are the wheel speed sensor connectors.

Answer:
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.

Question:
ABS light comes on and stays on is it safe to keep driving like this ?

Answer:
When the ABS light comes on in any GM vehicle, this means there is a problem in the anti-lock brake system and it has been disabled. This does not affect the normal braking system. You will just not have ABS.A common cause for the light is a faulty wheel speed sensor, or the wiring harness that come to the sensor . Most of todays vehicles have a sensor in each wheel. Scanning the computer for trouble codes will give an indication as to what part of the system has a problem.

2003 Chevy Venture Van ABS light. Question = Why does my ABS light comes on and stays on is it safe to keep driving like this ?

Answer:
The ABS light can come on for several reasons. A few common causes are that one of the ABS speed sensors has failed. The sensor is part of the wheel hub bearing. Or possibly the harness going to the sensor has a bad wire or water intrusion. It is safe to drive. When the ABS light comes on, the computer disables anti-lock operation, but normal braking system is not affected.
