• C0602
• C0604
This code means that the car's computer is having trouble with the level of voltage from the battery. It's like when your toy's battery is running low and it doesn't work right.
The C0603 code indicates an issue with the voltage level from the vehicle's battery, affecting the electronic control module.
C0603 is a chassis code that relates to the battery voltage being either too low or too high, which can impact the operation of the vehicle's electronic systems. It is detected by the control module monitoring the battery voltage.

• Vehicle in park with engine off
• Battery fully charged
The battery is typically located under the hood, near the front of the vehicle.
Q: Can I drive with a C0603 code?
A: It's not recommended as it may lead to electrical failures.
Q: How do I know if my battery is the problem?
A: Check the battery voltage with a multimeter; it should be around 12.6 volts when fully charged.
