Lack of communication with one or more modules in a vehicle can really slow down the diagnosis. SureTrack community member trannyman1 had a Nissan Rogue in the shop that wouldn’t drive and several codes. No communication with the TCM was the first problem. They posed the question to the community, and with the help of fellow community member Ericsautomotive and others, they were able to resolve the issue quickly.
While it is clearly necessary to check for circuit voltage, open circuits and shorted circuits, there are proper and improper methods to accomplish those tasks. Let’s take a brief look at three improper connector and wire testing methods here in this informative blog from our own Jake Schell.
Corrosion is a horrible monster. But never more insidious than when it affects the wiring. SureTrack community member carls4460 had a Ford F350 Super Duty truck that was towed in for a no-start condition. They thought they found the cause but that didn’t fix it. They posed the question to the community, and with the help of fellow community member Poppyshop and others, they were able to resolve the issue quickly.
Technicians love a mystery, or maybe not, when it involves wiring issues in a customer’s vehicle. SureTrack community member Freyson had a Cadillac DTS in their shop where the starter burned out because it wouldn’t stop cranking. They posed the question to the community, and with the help of fellow community member Dmckemie12 and others, they were able to resolve the issue quickly.
Gone are the days when the technician could just tap into a hot wire to power radios and other add-on accessories. The voltages present in many circuits are less than battery voltage and power sensitive electrical components. Splicing into circuits can cause any number of other problems that can lead to failures of costly components or assemblies. But with Mitchell 1’s TruckSeries by your side you can get rid of those problems for good. Learn all about it here.
Electrical issues can be hard to diagnose, especially when standard testing doesn’t reveal the problem. Sometimes you have to go inch by inch through the wiring to find the cause. SureTrack community member Mlopez2008 had a Mercedes-Benz CLK320 in their shop with a message on the dash and the cooling fan running any time the key was on. They posed the question to the community, and with the help of fellow community member Richard_C and others, they were able to resolve the issue quickly.
Electronic throttle controls have become ubiquitous on new vehicles. The days of the simple throttle cable are going away. Follow this Real Fix to see how a Chevrolet Cruze with an erratic throttle and a code P2135 was diagnosed and the problem that was found and corrected.
It’s always frustrating when you replace a part and the new one doesn’t work as it should. SureTrack community member bmaples had a BMW X3 SUV in the shop where they replaced a bad HVAC blower and now it only had a little bit of air coming out of the vents. They posed the question to the community, and with the help of fellow community member Ericsautomotive and others, they were able to resolve the issue quickly.
Sometimes a customer thinks they know what’s wrong with their vehicle when they bring it into your shop, but that can just be a distraction. SureTrack community member bmaples had a Chevrolet Silverado in the shop where the customer thought they had an EVAP leak but it was something else. They posed the question to the community, and with the help of fellow community member Ericsautomotive and others, they were able to resolve the issue quickly.
