Nissan And Infiniti ABS Service: Good Working Order Of The Basic Brake System Eases Diagnostics
On early models, wheel speed sensors send an AC voltage signal to the ABS control module. On later models, active wheel speed sensors change the voltage signal produced by the ABS control module. Active wheel speed sensors are more accurate and work at lower speeds. This is why they are found on most Nissan/Infiniti models after 2012.
Nissan Clunking Or Thumping Noise At Start Up
The above condition is normal and does not need repair. Each time the ignition is turned on and the vehicle is driven at about 16 mph, the ABS/VDC system performs a “Self-Check” to confirm components of the ABS/VDC system are operating correctly.
Steering Angle FAQs To Help Boost Your ABS & Stability Control Diagnostics
Chances are you will never crack open a steering angle sensor (SAS) cluster to repair it. But, this sensor should not be a mystery. To be effective at ABS and stability control diagnostics, knowing how sensors measure angles and information is critical.
Honda Accord With ABS Codes
This system will set codes when there is high resistance to the ground. Following the diagnostic tree in this case will have you replace the ABS modulator, when in most cases it can be repaired by cleaning the ground G203.
Diagnosing ABS And Vehicle Stability Control Issues
These driver aids are empowered by control unit monitor inputs from the wheel speed sensors, steering angle sensor and yaw sensor. Using these inputs, the control unit makes decisions and sends output commands to the ABS modulator and throttle body to help the car follow the course that is expected by the driver.
Mazda: Performing Regular Undercar Maintenance
Brake and suspension problems will surface in a couple of ways, the most common of which are noise-related. The suspension noise will generally be a knocking sound as the car is driven over bumps, or a noise when the steering wheel is turned. With the brakes, you’ll be hearing noise issues that range from an occasional squeak to a constant grinding noise.
Thorough Brake Inspections Are Comeback Preventers & Profit Builders
Learn how to use a simple, but effective, brake inspection procedure that takes the surprises out of the brake repair process.
Indirect Tire Pressure Monitoring Systems Making A Comeback On Some Imports
Indirect Tire Pressure Monitoring Systems (TPMS) are the systems that do not have air pressure sensors inside the tires. Rather, they detect a low tire by comparing relative wheel speeds via the Anti-lock Brake System (ABS) wheel speed sensors. New systems are taking advantage of better wheel speed sensors and modules to make indirect systems work. Indirect TPMS began making a comeback in 2011 on all Audi models. The highly popular Honda Accord switched to indirect TPMS for the 2013 model year.
Chrysler Tech Tip: ETC Light Illuminated Or Diagnostic Trouble Code P2122 And/Or P2127 Set
Some customers may experience an ETC light illumination. Upon further investigation, the technician may find that DTCs P2122 – Accelerator Pedal Position Sensor 1 Circuit Low and/or P2127 – Accelerator Pedal Position Sensor 2 Circuit Low have been set.
VIEWPOINT:Monday Morning MIL Light Quarterback
Monday mornings are typically not very productive for me. I typically will hide in my office with the light off to avoid people asking about their latest weekend-induced car problems.
Tech Tip: Nissan Maxima’s ABS Activates On Normal Braking, ABS Warning Lamp Is On
If you confirm that the ABS light is on with one or more of the following DTCs stored – C1105, C1110, C1124, C1126 – and/or the ABS system activates with normal braking, follow the Service Procedure.
Tech Tip: Generation 1 Wheel Bearings With Integrated ABS Tone Ring
The front wheel bearings listed in this Tech Tip all share a unique design feature. They are all double-row angular contact with a split inner ring. The distinctive feature on these bearings is that one of the two seals on the bearing has a built-in magnetic impulse wheel. Caution should be taken to make sure that the seal with the ABS impulse ring is installed in the correct direction.
