Truck Electrical Diagnosis & Repair

What is an Electronic Diagnosis?

The tools that technicians use now are technologically advancing just as quickly as the equipment itself. Diagnostic tools help streamline repairs by reading your vehicle's electronic sensors and control modules.

An electrical diagnosis can be helpful because it can pinpoint the exact location of the failure, which can then be repaired much more efficiently.

Example:
An analysis tool that analyzes the battery, starter, and alternator to determine where the problem lies.

Signs Your Truck’s Electrical System is Failing

The increased use of electronics in modern vehicles is causing a much greater strain on the battery than in the past. Many signs can show you that there may be an issue with your truck’s system and may need electrical repair.

Some examples include:

• Trouble starting
  If the engine is not starting correctly and you hear a “clicking” audio cue when turning the key, this normally means there is not enough juice in the battery to get your truck going.
• Headlight issues
  Your headlights, brake lights, and turn signals are necessary safety measures. These lights may dim if you’re having electrical problems.
• Blown fuses
  The fuses in your truck’s fuse box are designed to prevent overvoltage and short-circuiting. A blown fuse can indicate a larger electrical issue.
• Burnt plastic smell
  This is hazardous and may signal an electrical malfunction or short circuit.
• Battery issues
  Truck batteries typically last 3–5 years and can corrode over time. Since the battery is a key part of the electrical system, it must be properly maintained.

Types of Electrical Repair

There are many types of electrical repairs, many of which require an electrical diagnosis to determine the appropriate truck repair.

Major components that may require repair include:

• Starter
• Alternator
• Injection system
• Ignition system
• Lighting system
• Battery
• Display system

Additional components that work with your truck’s electrical system:

• Power mirrors
• Air suspension
• GPS
• Stereo system
• Anti-lock brakes

The electrical system in your truck is responsible for an ever-growing number of needs. Proper maintenance and diagnosis are critical to keeping these components functioning effectively.
