Back to Generation

The 2019 Toyota Camry (XV70) is generally regarded as a reliable vehicle, but like any car, it can experience electrical issues. Below are some of the most commonly reported electrical problems, along with symptoms, diagnostic steps, and potential solutions.

Most Reported Electrical Issues

  1. Battery Drain

    • Symptoms:
      • Car fails to start or has a sluggish start.
      • Warning lights on the dashboard.
      • Electrical accessories (e.g., radio, lights) function intermittently.

  2. Faulty Infotainment System

    • Symptoms:
      • Touchscreen is unresponsive.
      • System freezes or crashes.
      • Bluetooth connectivity issues.

  3. Malfunctioning Power Windows

    • Symptoms:
      • Windows do not respond to switch inputs.
      • Windows move slowly or only partially.
      • Window motor noise when trying to operate.

  4. Dashboard Warning Lights

    • Symptoms:
      • Check Engine, ABS, or other warning lights illuminated.
      • Inconsistent or erratic behavior of vehicle systems.

  5. Keyless Entry Issues

    • Symptoms:
      • Key fob not recognized by the vehicle.
      • Car does not unlock or start with the key fob.

Battery Drain

  1. Visual Inspection:

    • Check for any loose or corroded battery terminals.
    • Inspect for any lights that may be left on, including glove compartment and trunk lights.

  2. Parasitic Draw Test:

    • Tools Required: Multimeter.
    • Disconnect the negative battery cable.
    • Connect the multimeter in series between the negative battery terminal and the disconnected cable.
    • Record the current draw; anything above 50 mA suggests a parasitic draw.

  3. Isolate the Circuit:

    • Pull fuses one by one and observe the multimeter reading until the current draw drops significantly.

Faulty Infotainment System

  1. Soft Reset:

    • Hold the power button on the infotainment system for 10 seconds to reset.

  2. Software Update:

    • Check for available updates via the Toyota website or through the dealership.

  3. Check Fuses:

    • Tools Required: Fuse puller, multimeter.
    • Locate the fuse box, usually under the dashboard or in the engine compartment.
    • Inspect the infotainment system fuse and replace if necessary.

Malfunctioning Power Windows

  1. Check Window Switch:

    • Test the window switch with a multimeter for continuity.
    • If no continuity, replace the switch.

  2. Inspect Window Motor:

    • Tools Required: Screwdriver set, multimeter.
    • Remove the door panel to access the window motor.
    • Test the motor directly with a power supply to see if it operates.

  3. Inspect Wiring:

    • Check for damaged or frayed wiring in the door harness.

Dashboard Warning Lights

  1. OBD-II Scan:

    • Tools Required: OBD-II scanner.
    • Connect the scanner to the OBD-II port and retrieve any diagnostic trouble codes (DTCs).
    • Note any codes and refer to service manuals for troubleshooting.

  2. Visual Inspection:

    • Inspect wiring and connectors associated with the systems indicated by the warning lights.

Keyless Entry Issues

  1. Battery Check:

    • Replace the key fob battery and test.

  2. Reprogramming:

    • If the fob is still not recognized, follow the reprogramming procedure in the owner's manual.

  3. Check Antenna:

    • Inspect the keyless entry antenna located near the vehicle’s ignition or door handles for damage or disconnection.
