Code B2336 Chrysler Description
The B2336 Chrysler diagnostic trouble code indicates a problem with the horn control circuit being at a low voltage level. The horn control circuit is responsible for activating the vehicle's horn when the horn button is pressed by the driver. A low voltage level in this circuit can prevent the horn from functioning properly, which can be a safety concern as the horn is an essential communication tool on the road.
Common Causes of B2336 Chrysler
- Faulty horn switch: The horn switch may be malfunctioning, preventing the circuit from receiving the proper voltage signal.
- Damaged wiring: Wiring that is frayed, corroded, or broken can disrupt the flow of voltage in the horn control circuit.
- Blown fuse: A blown fuse in the horn circuit can result in a loss of power to the horn, causing it to be inoperative.
- Faulty horn relay: The horn relay is responsible for supplying power to the horn when the horn button is pressed. A faulty relay can result in a low voltage condition.
- PCM issue: In rare cases, a malfunction in the Powertrain Control Module (PCM) can cause the horn control circuit to register a low voltage level.
Symptoms of B2336 Chrysler
- Horn not working: The most obvious symptom of this code is the horn not producing any sound when the horn button is pressed.
- Horn sounds weak: If the horn does sound, it may be weak or muffled, indicating a low voltage issue.
- Horn activates on its own: In some cases, the horn may activate on its own without any input from the driver, which can be a nuisance and a potential safety hazard.
- Horn fuse blows repeatedly: If the horn control circuit is experiencing a short or overload, it may cause the horn fuse to blow frequently.
How to Fix B2336 Chrysler
- Check horn fuse: Start by checking the horn fuse to ensure it is not blown. Replace the fuse if necessary.
- Test horn switch: Test the horn switch for continuity to determine if it is functioning properly. Replace the switch if it is faulty.
- Inspect wiring: Inspect the wiring in the horn control circuit for any damage or corrosion. Repair or replace any damaged wiring.
- Test horn relay: Test the horn relay to ensure it is sending the proper voltage to the horn. Replace the relay if it is faulty.
- Check PCM: If all other components check out, consider testing the PCM for any malfunctions that may be causing the low voltage condition in the horn control circuit.
Cost to Fix B2336 Chrysler
The cost of repairing a B2336 Chrysler code can vary depending on the specific cause of the issue. On average, the cost of parts for this repair could range from $50 to $200, while the labor cost could be between $100 and $300. However, it's important to note that these are rough estimates and actual repair costs can vary based on the shop's labor rates, location, and the specific make and model of the vehicle.
