Electrical System Diagnostic Process
Our ASE certified technicians follow a thorough process to correctly identify electrical faults. Steps include:
- Battery Testing – We test battery voltage, load test, and check connections to verify if the battery is functioning properly. A weak battery can cause multiple issues.
- Visual Inspection – Our technicians visually inspect all electrical components for damage, corrosion, loose connections, and frayed wiring. This allows quick identification of many electrical faults.
- Electrical Testing – Using digital multimeters and test lights, we check for power and grounds at fuses, relays, switches, sensors, and wiring circuits. This pinpoints faults in specific circuits.
- Scan Tool Analysis – Scanner tools connect to the vehicle’s computer networks to check for diagnostic trouble codes (DTCs), data readings, and error messages that indicate issues.
- Simulating Conditions – To reveal intermittent faults, we simulate operating conditions such as mimicking hot or cold temperatures, engine load, vehicle vibration, and electrical spikes.
- Repair Verification – Once repairs are complete, we retest systems thoroughly to ensure the electrical issue is fixed correctly.
