P0562 RAM Code - Battery System Low Voltage
Quick Answer
The Electronic Voltage Regulation (EVR) system maintains the system voltage at a desired level by turning the Pulse Width Modulated (PWM) Alternator Field Control circuit (A) on and off. Common causes include Low battery charge, Battery defective, Loose or missing alternator drive belt. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0562 RAM Description
During normal operation, the voltage reading at the Alternator output stud will be very close to the target charging voltage viewed on the scan tool. This is the system voltage and is sensed by the Powertrain Control Module (PCM) through the Fused B+ circuit (B). With the Alternator connector plugged in, and back probing the Alternator Sense circuit (E), the voltage reading will be approximately 3.5 volts less than the voltage at the Alternator output stud due the resistor inside the Alternator. This is the Alternator Sense (E) input to the PCM. These two voltage sense inputs are used and compared during the different diagnostics performed on the EVR System by the PCM.
What are the Possible Causes of the DTC P0562 RAM?
- Low battery charge
- Battery defective
- Loose or missing alternator drive belt
- Faulty alternator
- Open or short system voltage circuit
- Faulty Powertrain Control Module (PCM)
How to Fix the DTC P0562 RAM?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.

Frequently Asked Questions about P0562 RAM Code
1. What does the OBDII code P0562 mean on a RAM vehicle?
P0562 indicates that the vehicle's Powertrain Control Module (PCM) has detected low voltage from the battery or charging system.
2. What are the common symptoms of code P0562 in a RAM vehicle?
Symptoms may include dim headlights, a dead or weak battery, difficulty starting the engine, stalling, or intermittent electrical issues.
3. What can cause a P0562 code on a RAM vehicle?
Common causes include a failing alternator, a weak or discharged battery, loose or corroded battery terminals, damaged wiring, or a malfunctioning PCM.
4. Can I continue driving my RAM with a P0562 code?
While it may be possible to drive for a short time, continued driving can result in stalling or complete loss of electrical power, potentially leaving you stranded.
5. How do I fix the P0562 code on my RAM vehicle?
Start by checking the battery voltage, inspecting the alternator for proper operation, cleaning battery terminals, and repairing any damaged wiring or connections.
6. How do I test the alternator to diagnose a P0562 code?
Use a multimeter to measure the output voltage of the alternator. It should read between 13.5 and 14.7 volts while the engine is running.
7. Can a bad battery cause the P0562 code on a RAM vehicle?
Yes, a weak or failing battery can trigger the P0562 code due to insufficient voltage being supplied to the electrical system.
8. What tools do I need to diagnose a P0562 code in my RAM?
You’ll need a multimeter to check voltage levels, a scan tool to read and clear codes, and basic tools to inspect and clean battery terminals.
9. How much does it cost to fix the P0562 code on a RAM vehicle?
The cost varies depending on the issue. Replacing a battery may cost $100–$300, while alternator replacement can range from $400–$800, including labor.
10. Can a P0562 code be triggered by extreme weather conditions?
Yes, extremely cold or hot temperatures can strain the battery and charging system, potentially causing low voltage and triggering the P0562 code.
