Possible Causes of B2190 Code in Nissan
The B2190 code in Nissan refers to a problem with the NATS (Nissan Anti-Theft System) antenna amplifier. This code indicates that there is a malfunction in the circuit that controls the antenna amplifier. Here are some of the possible causes of the B2190 code:
- Failed NATS antenna amplifier
- Shorted or open circuit in the NATS antenna amplifier wiring
- Failed NATS control module
- Corroded or damaged NATS antenna
- Failed key or key transponder
- Failed BCM (Body Control Module)
Failed NATS Antenna Amplifier
The most common cause of the B2190 code is a failed NATS antenna amplifier. This component is responsible for receiving the signal from the key and transmitting it to the NATS control module. If the amplifier fails, the signal cannot be transmitted, and the code will be triggered.
Shorted or Open Circuit in the NATS Antenna Amplifier Wiring
Another possible cause of the B2190 code is a shorted or open circuit in the wiring that connects the NATS antenna amplifier to the NATS control module. This can be caused by damaged or corroded wiring, or by a loose connection.
Failed NATS Control Module
If the NATS control module fails, it will not be able to receive the signal from the NATS antenna amplifier, and the B2190 code will be triggered. This is a less common cause of the code, but it can still occur.
Corroded or Damaged NATS Antenna
If the NATS antenna is corroded or damaged, it may not be able to receive the signal from the key, which can trigger the B2190 code. This is more likely to occur in older vehicles or in vehicles that have been exposed to harsh weather conditions.
Failed Key or Key Transponder
If the key or key transponder fails, it will not be able to transmit the signal to the NATS antenna amplifier, which can trigger the B2190 code. This is a less common cause of the code, but it can still occur.
Failed BCM (Body Control Module) B2190 Code Nissan:
The B2190 code in Nissan vehicles refers to a problem with the NATS (Nissan Anti-Theft System) antenna amplifier. This component is responsible for receiving signals from the key fob and transmitting them to the NATS control module. When the amplifier fails, the vehicle may not start or may stall while driving.
Here are some possible fixes for the B2190 code:
- Replace the NATS antenna amplifier: This is the most common fix for the B2190 code. The amplifier can be replaced with a new or refurbished unit, and the NATS system will need to be reprogrammed to recognize the new component.
- Check the wiring and connections: Sometimes the problem is not with the amplifier itself, but with the wiring or connections leading to it. A mechanic can inspect the wiring and connectors for damage or corrosion and repair or replace them as needed.
- Replace the NATS control module: In rare cases, the problem may be with the NATS control module rather than the amplifier. If this is the case, the control module will need to be replaced and the NATS system reprogrammed.
- Reset the NATS system: In some cases, simply resetting the NATS system can clear the B2190 code. This can be done by disconnecting the battery for a few minutes and then reconnecting it.
It’s important to note that attempting to fix the B2190 code without the proper knowledge and tools can cause further damage to the vehicle. It’s best to have a qualified mechanic diagnose and repair the issue. Additionally, if the vehicle is still under warranty, the repair may be covered by the manufacturer.
