What Causes Traction Control Warning Lights in a 2008 Saturn Vue AWD During Turns?
Asked Mar 3, 20160 views1 answer
I am experiencing an issue with my 2008 Saturn Vue AWD, which has a 3.6-liter engine. The traction control warning lights activate when I make a left turn, but I don’t see any lights when driving straight or turning right. I used an Innova 3150d code reader to check for ABS/SRS issues and found historical codes BO100 and BO142 related to the ABS system. While I know that BO100 indicates "electronic front end sensor, 1 performance," I cannot find a definition for BO142. I suspect there may be a speed sensor problem, but I am unsure if these codes are directly related to the ABS or traction control systems. Can anyone provide clarification on these codes or suggest the next steps for diagnosis?
Understanding Traction Control Warning Lights in Your 2008 Saturn Vue AWD
Experiencing warning lights on your dashboard can be concerning, especially when they seem to manifest under specific driving conditions. In your case, the traction control warning lights activating during left turns on your 2008 Saturn Vue AWD with a 3.6-liter engine may indicate underlying issues that need to be addressed. Below, we will explore the potential causes, the codes you’ve encountered, and steps for diagnosis and resolution.
Key Codes Explained
-
BO100 - Electronic Front End Sensor 1 Performance
- This code generally indicates a problem with the front wheel speed sensor or its circuit. It may affect the traction control system since it relies on accurate wheel speed data to function properly.
-
BO142 - Undefined Code
- Unfortunately, there is limited documentation available for this specific code in most generic OBD-II databases. It could relate to a performance issue within the ABS or traction control system, but further investigation may be needed.
-
C0267 - Low Brake Fluid Indicated
- This code is more straightforward, signaling that the brake fluid level is low. Since you've confirmed that the reservoir was low and you added fluid, this issue might have been the root cause of your traction control warning lights.

To address the traction control warning light on your 2008 Saturn Vue, start by disconnecting the positive battery connector. Leave it off for about five minutes before reconnecting it. This can help reset the engine control module (ECM) and may resolve the issue. After reconnecting the battery, check if any warning lights reappear.
If you encounter a code like `C0267`, which indicates low brake fluid, it's essential to check your brake fluid reservoir. If the fluid level is low, top it off and then disconnect the battery again for a couple of minutes. Reconnect it and see if the warning light persists or if any new codes appear.
Sometimes, even after disconnecting the battery, the code may still show up if the fluid level was low for a while. It’s a good idea to take your vehicle for a short drive after filling the brake fluid, as the system may need some time to recalibrate and clear any lingering codes.
If you have a code reader, you can use it to clear codes, but keep in mind that it might not clear everything. Disconnecting the battery is often the more effective method for a complete reset. If the traction control light doesn’t come back after a few drives, you should be in the clear. If it does reappear, or if you have any further questions, don’t hesitate to reach out for more assistance.
