Fault code B1352 is logged when the body control module (BCM) has detected a malfunction with the ignition key circuit. This code is logged when the key is inserted and one of the relevant circuits fails.
These systems are specific to when the key is only inserted in the ignition, prior to starting the vehicle.
Other Signs of This Problem
There can be some noticeable symptoms when it comes to this type of fault code. These are all related to the ignition system of the car.
The presence of the Check Engine light on the dashboard.is typically the most common sign for fault codes, but this code will often not present it. There is another very noticeable symptom though. This code can cause the vehicle to not crank at all.
What Could Be The Problem?
It can be fairly difficult to pinpoint the cause of the issue, but it will typically be found within the key or ignition system.
What causes the vehicle to not crank is that the BCM does not see that there is a key in the ignition, despite having the request signal to the starter.
This can be caused by a short or open circuit in the ignition key-in circuit. This can be caused by electrical faults within the circuit wiring and connections or the key itself.
One important circuit to check is the one for the door chimes. An electrical issue like loose wires or damaged connections in this circuit can cause this fault code as it is a part of the key-in ignition circuit. These circuits are notorious for having electrical issues for Ford and Jaguar.
A defective door chime component can also cause this problem.
Fixing this issue will typically involve electrical repairs to remove any circuit issues.
Another potential fix for this problem involves replacing faulty parts. These can include a defective key or door chimes.
Any loose wires or damaged connections in the key-in ignition circuit must be fixed. Be sure to check the door chime circuit as well, as this is a part of the key-in ignition circuit.
If it is determined that the BCM or PCM is defective, it should be replaced. If these modules are running on outdated software, they should be given the required updates.
Fault code B1352 is considered a fairly low problem in terms of seriousness. In some cases, the vehicle may be able to run completely fine even with the code. In other cases, the vehicle may not start at all.
In the case of an engine that is not cranking at all, it is a good idea to have this code fixed as soon as possible to allow the vehicle to start. Otherwise, the problem should be fixed whenever possible.
