Nissan Tech Tip: Permanent DTC (P-DTC) Information
Starting with 2010 Model Year, Nissan vehicles have been gradually incorporating a new type of DTC known as “Permanent DTC or P-DTC.” If a vehicle is equipped with P-DTCs, all emission-related DTCs will also set a P-DTC if the MIL is turned on.
BMW Tech Tip: Malfunctioning Steering Wheel Buttons
The customer may report a sporadic or continuous malfunction of the multifunction steering wheel buttons, and a message saying “Cruise control without function.”
TPMS Diagnostics: MINI Applications
In 2004, MINI was one of the early adopters of tire pressure monitoring systems. This was driven by the lack of space for a spare tire and the use of run-flat tires. The TPMS system on these early models was intended to warn the driver of a tire with low pressure so they could reduce speed and find the nearest shop.
Audi TPMS Diagnostics
Audi Tire Pressure Monitoring Systems (TPMS) are some of the easiest to reset and relearn. The automaker has used both indirect and direct systems during the past decade. Both systems use the same relearn procedure that involves accessing the TPMS settings through the driver information center or infotainment system. The only difference between direct and indirect systems is the last step that may involve driving continuously for 10 minutes or allowing the vehicle to sit for either 10 or 20 minutes.
Tech Tip: MINI PCV System Diagnostics And Measurement Of Pressure
All current MINI engines incorporate a pressure–controlled crankcase ventilation system that uses various crankcase ventilation valves, depending on the engine type. Although the valves all look different, they function similarly using a spring and diaphragm assembly to control the crankcase pressure.
Piercing And Probing Wires With The Least Damage Possible
Probably one of the most controversial topics among technicians is the probing and piercing of wires and connectors. Some technicians curse t-pins and piercing probes claiming they can damage a wiring harness, while others have zero problems stuffing a blunt multimeter lead into a connector for an ECM.
Getting The Big Squeeze: How Mazda’s New Spark-Controlled Compression Ignition Engine Runs Long On Fuel, Short On Emissions
Until Mazda recently introduced its new Spark-Controlled Compression Ignition (SpCCI) gasoline engine, internal combustion engines (ICEs) were classified as either spark or compression ignition. The historical differences between the two were obvious: spark-ignition engines were quiet and smooth and compression-ignition engines were not.
Bosch Wheel Service Line Includes Electric Center-Post Tire Changer
The new G-Frame Concept provides extreme rigidity, which reduces mount/demount flexion, virtually eliminating damage to wheels and tires, said the company.
MINI Undercar Service Opportunities Are Only An Inspection Away
With more than a million MINIs on the roads, a lot of opportunity exists for shops to service brakes and chassis.
TPMS Intel On VW Applications
Before any relearn or reset procedure is performed on a direct or indirect system, set the tires to the correct pressure. When the system is reset, it uses this pressure as the reference pressure. If it is not correct, the system might assume an incorrect pressure is the correct pressure.
Tech Tip: Subaru Electric Parking Brake Inoperative
This bulletin announces a new replacement EPB actuator assembly to address DTC C0251. In isolated cases, the automatic calibration function of the EPB actuator may not always occur when turning the ignition on.
