1. What is an Actron CP9135 OBD2 Code Reader and Scanner?

The Actron CP9135 OBD2 code reader and scanner is an entry-level tool designed to read and clear basic diagnostic trouble codes (DTCs) in OBD2-compliant vehicles. It helps identify common issues related to the engine, emissions, and basic electrical systems.

1.1. Key Features of the Actron CP9135

The Actron CP9135 typically includes features such as:

• Reading and clearing OBD2 diagnostic trouble codes (DTCs)
• Displaying freeze frame data
• I/M readiness monitors for emissions testing
• Live data stream (limited parameters)
• Code definitions on screen

1.2. Limitations of the Actron CP9135

While the Actron CP9135 is useful for basic diagnostics, it has limitations:

• Limited System Coverage: It primarily focuses on engine and emissions-related codes. It might not access other systems like ABS, SRS, transmission, or body control modules.
• Basic Functionality: It offers basic code reading and clearing, but lacks advanced functions like bi-directional controls, module programming, or advanced data analysis.
• Compatibility: While it works on OBD2-compliant vehicles (typically 1996 and newer), it may not support all vehicle-specific codes or systems, especially in luxury vehicles like Mercedes-Benz.

2. Understanding OBD2 Code Readers and Scanners

OBD2 (On-Board Diagnostics II) is a standardized system used in most vehicles to monitor and diagnose engine and emissions-related issues. An OBD2 code reader or scanner connects to the vehicle’s diagnostic port to retrieve diagnostic trouble codes (DTCs) and other data.

2.1. How OBD2 Scanners Work

OBD2 scanners work by:

1. Connecting to the vehicle’s OBD2 port (usually located under the dashboard).
2. Reading diagnostic trouble codes (DTCs) stored in the vehicle’s computer.
3. Displaying the codes and their descriptions to the user.
4. Allowing the user to clear the codes after addressing the underlying issue.
5. Providing live data streams from various sensors in the engine and related systems.

2.2. Types of OBD2 Scanners

There are different types of OBD2 scanners available, ranging from basic code readers to advanced diagnostic tools:

• Basic Code Readers: These are simple, inexpensive tools that only read and clear DTCs. They are suitable for basic diagnostics and DIYers.
• Mid-Range Scanners: These offer additional features like live data, freeze frame data, and enhanced code definitions. They are suitable for more in-depth diagnostics.
• Advanced Diagnostic Tools: These are professional-grade tools that offer advanced features like bi-directional controls, module programming, and access to vehicle-specific systems. They are used by professional technicians and enthusiasts.

3. Diagnosing ETS/ABS Issues in Mercedes-Benz Vehicles

ETS (Electronic Traction System) and ABS (Anti-lock Braking System) are critical safety systems in Mercedes-Benz vehicles. When the ETS or ABS light comes on, it indicates a problem within these systems.

3.1. Common Causes of ETS/ABS Light Activation

Several factors can trigger the ETS/ABS lights in a Mercedes-Benz:

• Wheel Speed Sensors: Faulty or damaged wheel speed sensors can disrupt the ABS and ETS functions.
• Brake Light Switch: A malfunctioning brake light switch can cause issues with the ABS and ETS systems.
• Low Battery Voltage: Insufficient battery voltage can lead to various electrical issues, including ABS and ETS malfunctions.
• Steering Angle Sensor: Problems with the steering angle sensor can affect the ETS system’s operation.
• Hydraulic Pump or Module: Issues with the ABS hydraulic pump or control module can also trigger the warning lights.

3.2. Why the Actron CP9135 May Not Read ETS/ABS Codes

The Actron CP9135 is primarily designed to read engine and emissions-related codes. It may not have the capability to access the ABS/ETS control module or read the specific codes stored within that system. This is because:

• Limited System Coverage: The Actron CP9135 is an entry-level tool with limited system coverage compared to professional-grade diagnostic tools.
• Proprietary Codes: ABS/ETS systems often use proprietary codes that are specific to the vehicle manufacturer (Mercedes-Benz in this case). The Actron CP9135 may not be programmed to read these codes.

3.3. Alternative Diagnostic Tools for ETS/ABS Issues

To diagnose ETS/ABS issues in a Mercedes-Benz, you may need a more advanced diagnostic tool that:

• Supports ABS/ETS Diagnostics: Specifically states that it can read and clear ABS/ETS codes.
• Offers Bi-Directional Controls: Allows you to activate ABS components (like solenoids and pumps) for testing purposes.
• Provides Live Data: Displays real-time data from the ABS/ETS sensors and modules.
• Supports Mercedes-Benz Specific Codes: Can read and interpret proprietary Mercedes-Benz diagnostic codes.

Examples of such tools include:

• Mercedes-Benz Star Diagnosis: The official diagnostic system used by Mercedes-Benz dealerships.
• iCarsoft MB II: A popular aftermarket scanner that supports Mercedes-Benz diagnostics.
• Autel MaxiSys: A professional-grade diagnostic tool with extensive vehicle coverage and advanced features.
• Launch X431: Another professional-grade tool that supports a wide range of vehicles and systems.

4. Resetting IM Readiness Functions

IM (Inspection and Maintenance) readiness monitors are a set of tests that the vehicle’s computer performs to ensure that the emissions system is functioning correctly. These monitors must be in a “ready” state for the vehicle to pass an emissions test.

4.1. Using the Actron CP9135 to Reset IM Readiness

The Actron CP9135 can be used to reset the IM readiness monitors after a repair or when the monitors have been cleared due to a disconnected battery or other issue.

4.2. When to Reset IM Readiness

You may need to reset the IM readiness monitors in the following situations:

• After repairing an emissions-related problem.
• After clearing diagnostic trouble codes (DTCs).
• After disconnecting or replacing the vehicle’s battery.
• Before taking the vehicle for an emissions test.

4.3. Procedure for Resetting IM Readiness

The exact procedure for resetting IM readiness monitors may vary depending on the vehicle and the scanner. However, the general steps are as follows:

1. Connect the Actron CP9135 to the vehicle’s OBD2 port.
2. Turn the ignition key to the “ON” position (engine off).
3. Navigate to the “I/M Readiness” or “Monitors” menu on the scanner.
4. Follow the on-screen instructions to reset the monitors.
5. Drive the vehicle for a specified period or under certain conditions to allow the monitors to complete their tests.

5. Addressing Brake Light Issues and Their Impact on ETS/ABS

A malfunctioning brake light can indeed affect the ETS/ABS systems in a Mercedes-Benz. The brake light switch is a critical component that provides input to the ABS and ETS control modules.

5.1. How Brake Light Issues Can Affect ETS/ABS

Here’s how a faulty brake light or brake light switch can impact these systems:

• ABS Malfunction: The ABS system relies on the brake light switch to detect when the brakes are applied. If the switch is faulty, the ABS may not function correctly, leading to the ABS light illuminating.
• ETS/ESP Interference: The Electronic Traction System (ETS) or Electronic Stability Program (ESP) also uses the brake light switch signal. A faulty switch can cause these systems to malfunction, resulting in the ETS/ESP light turning on.
• False Signals: Arcing or grounding issues in the brake light circuit can send false signals to the control modules, triggering the warning lights.

5.2. Troubleshooting Brake Light Problems

To troubleshoot brake light issues, consider the following steps:

1. Inspect Bulbs: Check all brake light bulbs for damage or burnout. Replace any faulty bulbs.
2. Check Bulb Sockets: Examine the bulb sockets for corrosion or damage. Clean or replace the sockets as needed.
3. Test Brake Light Switch: Use a multimeter to test the brake light switch for continuity and proper function. Replace the switch if it’s faulty.
4. Inspect Wiring: Check the wiring harness and connectors for any signs of damage, corrosion, or loose connections. Repair or replace any damaged wiring.

5.3. Replacing the Stop Light Switch

If you suspect a faulty stop light switch, replacing it is a good idea. Ensure that the new switch is properly adjusted to avoid any deadband spots in the plunger’s travel.
