Code B2336 RAM Description
The B2336 diagnostic trouble code (DTC) refers to a Horn Control Circuit Low error, indicating that the vehicle's horn control circuit is detecting a lower than normal voltage level. This can result in the horn not functioning properly or not working at all. The horn control circuit is responsible for sending signals to the horn to produce the audible sound when the horn button is pressed. If the voltage is too low, the horn may not sound at all, which can be a safety concern for the driver and other road users. The issue could be caused by a faulty horn switch, wiring issues, or a problem with the horn relay.
Common Causes of B2336 RAM
- Faulty horn switch
- Wiring issues such as frayed or damaged wires
- Faulty horn relay
- Corrosion or poor connections in the horn circuit
- Electrical system issues such as a low battery voltage
Symptoms of B2336 RAM
- Horn not working or producing a weak sound
- Horn sounding intermittently or erratically
- Horn not responding when the horn button is pressed
- Horn fuse blowing repeatedly
