Mini Cooper Tech Tip: False ‘Service Due’ Message For Brake Pad Thickness
Brake pad thickness warning message is displayed even if the pads are above specifications. The mathematical calculations made by the Condition Based Services Module (CBS) do not agree with the actual brake wear. The CBS uses inputs like vehicle speed, pedal pressure and rotor temperature to determine if the pads require replacement.
SKF Tech Tip: Reusing Circlips
Circlip retainers are important to help maintain the proper seating and function of the wheel bearing. Depending on the vehicle application, there may be one or two circlips that facilitate retention of the bearing.
Acura Tech Tip: Clunk From The Rear Suspension When Hitting Bumps
Inspect the rear dampers for any leaks or damage to make sure the dampers themselves are not the cause of the noise. Replace the damping rubber from both rear dampers with the updated damping rubber in the repair kit.
Kia Tech Tip: AWD System Hydraulic Actuator Replacement
This bulletin provides the procedure for replacement of the hydraulic actuator of some All-Wheel Drive (AWD)-equipped 2011-2016 Sportage trucks (produced from May 6, 2010-February 19, 2013) and some AWD-equipped 2011-2015 Sorento models (produced from October 24, 2009-December 11, 2014).
SAAB Tech Tip: Low Oil Pressure And Code P0521
Some customers may complain of low oil pressure, no oil pressure, and/or engine noise as well as a possible P0521, which may be the result of a sticking oil pump pressure relief valve. In some instances, this may occur intermittently if the valve frees up when the engine cools down.
Jaguar Tech Tip: Humming Noise From Accessory Drive Belt Idler Pulley
A humming noise may be evident from the engine when the engine is idling. This may be caused by dust or water ingress to the accessory drive belt idler pulley bearing. The idler pulley bracket assembly (C2D51367) must be replaced as a complete assembly and must not be dismantled to a lower level.
Honda Tech Tip: Low Tire Pressure And TPMS Indicator On After Recent Tire Replacement
The Honda CR-V uses an indirect TPMS system that uses the rolling circumference of the tire to determine the pressure in the tire. Differences in sidewall construction and weight of a replacement tire can cause the rolling circumference to change if a single tire is replaced.
Air Ride Diagnostics: Thinking Through The Problem And Not Swapping Parts
Air ride systems can control vehicle ride height, passenger comfort and improve handling. How they operate and work with the rest of the systems on the vehicle is part of the embedded logic of their control system.
Fuel Trim Diagnostics: Should You Trust The Sensors?
Fuel-injected engines can adjust the fuel trim by altering the injector open time. The longer the open-time of the injector, the greater amount of fuel is injected into the engine.
TPMS Radio Frequency Theory And Operation
A typical wheel-mounted TPMS sensor will transmit data about tire pressure and temperature. Newer, tire-mounted models can also gauge acceleration and, in some cases, the direction that the wheel is spinning. Some systems display tire pressure by location on the instrument panel, but most do not.
Attention To Tension: Why Start-Stop Engines Still Require Belt Diagnosis
As many start-stop vehicles are aging out of warranty, you are likely to be encountering them in your service bays. Whether they are a true hybrid vehicle or have a conventional powertrain, attention to the underhood condition of the belts can be a profit center for you as well as a safety check for your customers.
Volkswagen Electronic Parking Brake Service
The majority of Volkswagen vehicles sold in the past five years have electronic parking brakes. Most customers don’t even realize that the vehicle has an electronic parking brake. The system engages and disengages the parking brake automatically on most vehicles.
