Dave Redinger's The Neighborhood Mechanic - "Telematics"


PHOTO

On my radio show we have a segment we refer to as the “auto glossary”. Today’s word is “telematics”. Telematics is the term that industry has coined to describe a new series of wireless devices that are available for use in today’s vehicles. Good examples are GM’s Onstar. Onstar is wireless service that monitors your position by GPS and supplies a series of helpful services such as unlocking your doors, transmitting your cell phone calls and calling for assistance when required. On board navigation systems are also referred to as telematics. The most universal of the telematic products is the use of ‘Bluetooth”. Currently it is used to relay your cell phone to the car’s sound system. The next level, look for this technology to actually operate the various accessories in the vehicle. First step in the process, the sound system. By utilizing the current technology engineers have successfully operated video and audio components in high end installations. Greatly reducing the need to wire the system. The benefits are many, less complicated installs and less chance of mechanical failure. The final result of telematics. vehicle systems that can be service rapidly if they actually require any service at all. Telematics is the hottest word in Motown today.

I have a 1990 Oldsmobile Eighty Eight Royal that starts great in the warmer months but during the winter months doesn't. If I don't plug in the block heater the vehicle seems to flood. Basically what I do to start the engine is hold the ignition on until the engine starts. This sometimes takes up to a minute. Any suggestions?

When the temperature dips a car's battery reserves are low. Sometimes less than 50% of it's available power. Under these conditions the ignition system must be in perfect condition. These vehicles had a reputation for weak ignition coils. Have the ignition system tested by a qualified tech. Never crank an engine for more than 10 seconds at a time. The starter may over heat and fail.

I have a 94 Honda Accord and for some reason the car will shut off will I'm driving. If I turn off the car and go back to restart in about 5 minutes, it will turn on. I took it to a mechanic and he says that the relay needs to be changed. Can you me give advice on what you may think of this problem. Sharon

Your tech is correct. This type of failure is electrical in nature. Your model is known for having issues with the PMFI relay. This relay powers the injection system and just wears out over the years. When in the shop have them check the ignition switch assembly. Some Hondas had problems in this area. By the way watch the number keys you hang from the ignition switch. All that weight swing back and forth just wears out the lock.
