Transponder Chip: A tiny chip installed in the car trick having a one-of-a-kind identification code.
Immobiliser Control Device (ICU) or Immobiliser ECU: This unit checks out the transponder code when the key is placed right into the ignition.
Engine Control Unit (ECU): The ECU obtains a signal from the ICU. If the codes match, the ECU allows the engine to start. If they do not, the engine continues to be immobilised.
Common Immobiliser Issues in Peugeot 107, Citroen C1, and Toyota Aygo:

Several issues can trigger immobiliser troubles in these automobiles:

Faulty Transponder Chip: The chip in the key can end up being damaged or shed its programs.
Faulty Immobiliser ECU (ICU): The ICU itself can malfunction, preventing it from checking out the transponder code or communicating with the ECU.
Electrical Wiring Issues: Troubles with the wiring in between the key antenna, ICU, and ECU can interrupt interaction.
ECU Issues: In uncommon situations, the ECU itself can have problems that influence the immobiliser system.
B2795 and B2799 Mistake Codes: These certain fault codes are commonly related to immobiliser problems.
Understanding B2795 and B2799 Fault Codes:

These codes specify to the immobiliser system in these lorries and generally suggest interaction issues.

B2795: This code typically relates to a problem with the communication between the essential transponder and the immobiliser ECU (ICU). It can show a damaged transponder chip, a problem with the antenna ring around the ignition barrel, or a mistake within the ICU itself.
B2799: This code often indicates a trouble with the interaction between the immobiliser ECU (ICU) and the engine ECU. It can suggest a circuitry concern, a damaged ICU, or a issue with the engine ECU.
