![]() ![]() active brake booster with integral solenoid.The 4-channel anti-lock brake system with traction control and stability assist system consists of the following components: yellow anti-lock brake warning indicator. ![]() The 3-channel anti-lock brake system consists of the following components: When traction control system is turned off, TRACTION OFF warning light comes on.EBTCM monitors transaxle temperature throughĪnti-Lock Control -Vehicles Built After 03/2002 ![]() Switch allows driver to select traction control mode (on/off). Powertrain Control Module (PCM) can also command EBTCM to set a Code 75 which will illuminate TRACTION OFF indicator.Traction control switch is located either on instrument panel center trim plate or driver's front door trim panel. During self-test, EBTCM commands TRACTION OFF indicator warning light on. The ABS/TCS FUNCTIONAL CHECK will either indicate ABS/TCS is functioning properly or direct technician to various diagnostic procedures such as diagnostic charts, symptom diagnosis or BRAKE warning light diagnosis.CHART D - TRACTION OFF WARNING LIGHT ON CONTINUOUSLY & NO DTC SET (BUICK WITH UH8 OR U2A INSTRUMENT CLUSTER)Circuit DescriptionWhen ignition switch is first turned to RUN position, EBTCM goes through a self-test, which lasts 2-4 seconds. If no failures are found during pre-diagnostic inspection, go to ABS/TCS FUNCTIONAL CHECK. If failures are found during pre-diagnostic inspection, perform necessary repairs, and proceed with ABS/TCS FUNCTIONAL CHECK. There are no provisions for flash code diagnostics.Begin ABS/TCS diagnosis with PRE-DIAGNOSTIC INSPECTION procedure. Fault codes stored by EBCM/EBTCM can be displayed using Tech 1 scan tester. Always perform ABS/TCS system functional check before using DIAGNOSTIC CODE CHARTSThe EBCM/EBTCM has self-diagnostic capability, which can detect system failures. Ensure parking brake switch is functioning properly. Check brake fluid level in Pressure Modulator Valve (PMV) assembly reservoir. Check brake fluid level in master cylinder reservoir. 1D, 5B and 6B in instrument panel fuse block. Check harness routing pay particular attention to wheel speed sensor wiring harness routing. PRE-DIAGNOSTIC INSPECTIONBefore diagnosing ABS/TCS, perform a comprehensive visual inspection of system as follows.Check ABS/TCS wiring harness connectors for looseness. Addressing the issue promptly will help ensure the continued safe operation of your vehicle. It's important not to ignore these warning lights, as the stability control system is designed to enhance vehicle safety and performance, particularly in adverse driving conditions. Once the problem is identified, they can recommend the necessary repairs or replacements. They can perform a diagnostic scan using specialized equipment to pinpoint the exact issue that is causing the warning lights to stay on. To diagnose and address the problem, you should take your Saturn Outlook to a qualified mechanic or a dealership. Low Fluid Levels: Low brake fluid levels can trigger the warning lights, as the stability control system may interpret it as a potential issue with the braking system.A malfunction in this sensor can lead to warning lights. Faulty Steering Angle Sensor: The steering angle sensor is part of the stability control system.Brake System Issues: Problems with the vehicle's braking system, including worn brake pads, can sometimes lead to issues with the Stabilitrak system.Malfunctioning Control Module: The control module responsible for the stability control system can develop faults or errors over time.Damaged Wiring: Damage to the wiring that connects the wheel speed sensors to the control module can disrupt the communication and trigger the warning lights.If there is a problem with the ABS module, it can affect the functionality of Stabilitrak and Traction Control. Faulty ABS Module: The Anti-lock Braking System (ABS) module is closely related to the stability control system.If one of these sensors is malfunctioning or dirty, it can trigger the warning lights. Wheel Speed Sensor Issues: The Stabilitrak and Traction Control systems rely on information from wheel speed sensors to determine if a wheel is slipping or losing traction.Here are some common reasons for the warning lights to stay on: There are several potential causes for these warning lights, and it's essential to address the issue promptly to ensure your vehicle's safety and performance. This system helps maintain control and stability during adverse driving conditions, such as wet or slippery roads. When the Stabilitrak and Traction Control indicators come on and stay illuminated in your 2008 Saturn Outlook, it typically indicates a problem with the vehicle's stability control system. ![]()
