Service Traction System light comes on when you turn the wheel to right is there a wire that may be pinched your 2002 Buick rendevous?

It's possible a pinched wire is causing your Service Traction System light to illuminate only when turning the right, but it's not the most likely cause. The light's behavior suggests a problem related to steering angle sensor feedback. The sensor communicates wheel position to the traction control system. Turning right may be stressing a connection or component related to this sensor more than turning left.

Here's why a pinched wire is less likely and what's more probable:

* Location of Wiring: While pinched wires are a possibility anywhere in the vehicle, the wiring related to the steering angle sensor is typically routed in protected areas near the steering column and rack. Pinching would be less common here than other areas with more exposed wiring harnesses.

* More Likely Culprits:

* Steering Angle Sensor (SAS): This is the most common cause. It can malfunction, become loose, or have a faulty connection. The turning motion may be exacerbating an existing problem within the sensor itself.

* SAS Wiring Connector: A loose or corroded connector at the sensor is more likely than a pinched wire along its length.

* Faulty Traction Control Module (TCM): Less common, but the TCM could be malfunctioning and misinterpreting signals from the SAS.

* Low Battery Voltage/Electrical Issues: Though less probable related to turning, a low battery or other electrical problem might be making a marginal component fail under stress (like the turning of the wheel).

What to do:

1. Check the obvious: Look for any obvious damage to the wiring harness near the steering column. This is less likely to be the root cause, but worth a quick visual inspection.

2. Have the SAS checked: This is the best first step. A mechanic can use a diagnostic scanner to read codes and check the sensor's readings. They can also inspect the connector for corrosion or damage.

3. Professional Diagnosis: Don't attempt complex repairs yourself unless you have significant automotive electrical experience. The diagnostic equipment needed to properly troubleshoot this is usually found only in repair shops.

In short, while a pinched wire *could* be the problem, focusing on the steering angle sensor and its associated wiring and connections is a far more efficient approach to troubleshooting.
