Safety Precautions

Danger:

• When an engine is operating, keep the service area WELL VENTILATED or attach a building exhaust removal system to the engine exhaust system. Engines produce carbon monoxide, an odorless, poisonous gas that causes slower reaction time and can lead to serious injury or death.

Warning:

• When working with hydraulic or fuel lines, liquids under pressure may escape and create a dangerous condition. Never open a bleeder valve or loosen a hydraulic line while the ABS is pressurized. Use adequate ventilation and make sure there are no sparks or possibility of sparks present that may ignite any vapor.

• Wear an American National Standards Institute (ANSI) approved eye shield when testing or repairing vehicles. Objects propelled by whirling engine components or pressurized liquids escaping may cause personal injury.

• Set the parking brake and block the wheels before testing or repairing a vehicle. It is especially important to block the wheels on front-wheel drive vehicles because the parking brake does not hold the drive wheels.

• Do not drive the vehicle and operate the NGIS tool at the same time. Any distractions may cause an accident. Have one person operate the NGIS tool as another person drives the vehicle.

• Maintain adequate clearance around moving components or belts during testing. Moving components and belts can catch loose clothing, body parts, or test equipment and cause serious damage or personal injury.

• Automotive batteries contain sulfuric acid and produce explosive gases that can result in serious injury. To prevent ignition of gases, keep lighted cigarettes, sparks, flames, and other ignition sources away from the battery at all times. If you are using the battery as a power source, connect the RED (+) battery clip to the positive vehicle battery terminal and connect the BLACK (-) battery clip to a good ground away from the battery.

• Refer to the service manual for the vehicle being serviced and adhere to all diagnostic procedures and precautions. Failure to do so could result in air bag deployment, personal injury, or otherwise unneeded air bag system repairs.

• Only use specially designed replacement parts (brake hoses and lines) for ABS-equipped vehicles.

• After bleeding the brake system, check the brake pedal for excessive travel or a “spongy” feel. Bleed again if either condition is present.

• When installing transmitting devices (Citizen Band radio, telephone, etc.) on ABS-equipped vehicles, do not locate the antenna near the ABS control unit or any other control unit.

Safety Precautions

Important:

• To avoid damaging the NGIS tool or generating false data, make sure the vehicle battery is fully charged and the connection to the vehicle DLC is clean and secure.

• Never disconnect or reconnect any electrical connector while the ignition is on. Damage to the ABS control unit may result.

• Do not hammer speed rings into the hub or tap on speed sensor components (sensor, sensor rings, etc.). Speed rings must be pressed, not hammered, into the hub and striking or tapping speed sensor components can cause demagnetization or a loss of polarization, affecting the accuracy of the speed signal returning to the ABS control unit.

• Use the recommended anti-corrosion coating on speed sensor components: Do not contaminate with grease.

• When speed sensor components have been removed, be sure to check the sensor-to-ring gap, when applicable.

• Do not mix tire sizes. Increasing the width slightly is acceptable but rolling diameter must be identical for all tires. Some manufacturers recommend tires of the same brand, style, and type. Failure to follow this precaution may cause inaccurate wheel speed readings.

• Do not expose the ABS control unit to prolonged periods of high heat: 185 degrees F/85 degrees C for 2 hours is considered a maximum limit.

• Use a recommended brake fluid, do not use silicone brake fluids in an ABS-equipped vehicle.

• Before bleeding the brake system, make sure no diagnostic codes are present.

• Do not let the master cylinder run dry during the brake bleeding procedure.

• Do not allow brake fluid to contact the motor pack or the electrical connectors.

VW Problems:

• Be aware of the following issue regarding year 2000 and 2001 VW Golf, GTI, Jetta/Bora, and Beetle air bag controllers:

• There are reports of Air bag warning lights staying on permanently after scanning with a scan tool. The Air bag controller shows DTC number 65535, indicating an internal error which cannot be cleared. This problem seems to be limited to air bag controllers with the part number 6Q0-909-605-A. There are a number of different “index” or “color-code” variations of this controller and not all of them are affected. If you have a 2000 or 2001 Golf, Jetta/Bora, Beetle, or a similar SEAT or Skoda model, physically inspect the air bag controller and look at the part number. If it is not 6Q0-909-605-A, then it should be safe to test. If it is Q0-909605-A, then it is at risk of this problem — avoid testing the air bag controller.

Introduction

1: General Information

Introduction

ABS / Air Bag 2004 is a software program for the Next Generation Information System (NGIS) tool. With the software installed (and unlocked) in the NGIS tool, and with the tool properly connected to a vehicle’s electronic control unit (ECU), you can use the software to read the vehicle’s anti-lock brake system (ABS) and air bag information and to perform device control tests.

Figure 1.1: NGIS Tool Connected to Vehicle DLC

Some of the functions provided by the ABS / Air Bag 2004 software include the following:

After you enter vehicle information into the NGIS tool, the

•

software displays an illustration of the cables required for connecting the NGIS tool to the vehicle’s ECU. After you connect the correct cables, the software automatically determines the tests available for that vehicle.

• The software automatically saves the most recently used

vehicle setup for you to reuse quickly. You can also save vehicle setups for reuse.

• You can view “live” sensor and switch datastream infor-

mation while it is being communicated from the vehicle’s ECU.

• The tests let you read diagnostic trouble codes (DTCs)

for air bags and anti-lock brake systems. (In addition, you can manually enter diagnostic codes for vehicles without readable electronic control units.)

• Record (Save) and Playback functions let you record and

replay datastream DTC information similar to a video recorder function.

• An automatic diagnostic code triggered record function

automatically creates a recording for playback and alerts you whenever a diagnostic code occurs during testing.

• A Post Collision test provides instructions for testing air

bags after repair(s).

• Pathfinder and Vehicle Info functions let you view vehicle-

specific information, such as technical service bulletin (TSB) references, vehicle specifications, repair instructions, ECU component location(s), and brake bleed procedures.

• The tests include programmed diagnostic procedures

(special tests) you can use for bi-directional control tests on anti-lock brake systems.

IMPORTANT: Be aware of the following issue regarding year 2000 and 2001 VW Golf, GTI, Jetta/Bora, and Beetle air bag controllers: There are reports of Air bag warning lights staying on permanently after scanning with a scan tool. The Air bag controller shows DTC number 65535, indicating an internal error which cannot be cleared. This problem seems to be limited to air bag controllers with the part number 6Q0-909-605-A. There are a number of different “index” or “color-code” variations of this controller and not all of them are affected. If you have a 2000 or 2001 Golf, Jetta/Bora, Beetle, or a similar SEAT or Skoda model, physically inspect the air bag controller and look at the part number. If it is not 6Q0-909-605A, then it should be safe to test. If it is Q0-909605-A, then it is at risk of this problem — avoid testing the air bag controller.

About Datastream

3: Datastream

The Datastream function lets you view live ABS and air bag data from a vehicle’s electronic control unit (ECU). This chapter describes how to use the Data-stream function.

About Datastream

Datastream is the communication of information between the sensors, computer, and actuators (switches) on a vehicle. The sensors monitor the vehicle systems and send data to the vehicle computer, the computer uses the data from the sensors to determine if any vehicle systems need adjusting. If so, the computer converts the data into commands and sends the commands to the actuators. The actuators then convert the commands to mechanical actions that adjust the vehicle systems.

As this stream of data is being communicated in the vehicle, the software can read the vehicle computer and display the data information in a readable format, called datastream. This lets you view “live” sensor and switch readings.

Basic Datastream Procedure

Use the following steps to obtain a basic understanding of how the Datastream function works.

Note: Before performing this procedure, follow the instructions in “Chapter 2:

To use the datastream function, follow these steps:

Read Codes / Clear Codes (Flash Codes)

If a vehicle requires that you read diagnostic trouble codes by visually viewing them as “flash codes,” the Read Codes and Clear Codes menu options appear directly on the Diagnostic Menu screen (instead of the Diagnostic Codes option).

For this type of vehicle, you identify the vehicle’s “flash code” numbers and manually enter the numbers into the NGIS tool to see their descriptions. The Read Codes function provides instructions for how to physically view the flash codes and lets you enter the code numbers to see their descriptions. The Clear Codes function provides instructions for how to manually clear flash codes from the vehicle.

Note: Flash codes are DTCs that you identify by: 1) grounding a pin on the vehicle’s check connector to trigger a specific indictor light to blink, and 2) viewing and counting the number of times the indicator light blinks.

The bleed tests remove air from the internal brake fluid chambers after servicing the brakes. For some vehicles, the NGIS tool runs the test automatically; for other vehicles, the tool displays instructional screens for you to perform the test manually.

The test usually cycles the valve solenoids so you can use brake pedal feel to diagnose solenoid problems, pump output problems, and pedal feel complaints. The final phase of the test releases brake pressure from each hydraulic channel in sequence, allowing you to identify pedal travel problems, solenoid leakage, or internal problems.

IMPORTANT:

• Before bleeding the brake system, make sure no diag-

nostic codes are present.

• Do not let the master cylinder run dry during the brake

bleeding procedure.

• Do not allow brake fluid to contact the motor pack or

the electrical connectors.
