The B1363 trouble code detects an error with the ignition start circuit.
The B1363 code is a generic OBD-II trouble code that signals an ignition start circuit malfunction. If the powertrain control module (PCM) or body control module receives an abnormal voltage reading from the ignition start circuit, then the B1363 trouble code is likely to be stored.
The B1363 trouble code can be caused by numerous different things, such as:
A vehicle with a detected B1363 trouble code may experience problems starting. The engine may turn over multiple times before starting, or the vehicle may simply be incapable of starting. It is also common for the check engine soon Warning Light to illuminate on the vehicle’s instrument panel.
The B1363 code should be diagnosed using a standard OBD-II trouble code scanner. A trustworthy mechanic will look at the freeze frame data to help diagnose the code, and to look for any additional trouble codes. If numerous trouble codes are present, then the mechanic should inspect them in the order in which the scanner displays them. Next, the trouble codes will need to be reset, and the vehicle restarted, so the mechanic can check to see if the code remains detected. If not, then the B1363 code was likely inaccurately detected, or was caused by an intermittent error.
If the code remains stored following this reset, the mechanic will begin by visually inspecting the electrical components in the ignition start system. Any damaged wires, corroded connectors, or blown fuses should be replaced. The technician will then check the circuit and battery voltage, and inspect the battery cables. If the issue remains, then an inspection of the ignition switch, starter motor, and starter solenoid will be required.
After any replacements or repairs are made, the technician will again reset the trouble codes, restart the vehicle, and check for the presence of the B1363 code, as this helps the mechanic determine when the issue is resolved.
The most frequently made mistake when diagnosing the B1363 trouble code is the failure to adhere to the OBD-II diagnosis protocol. It’s important for technicians to always follow the protocol step by step, as this increases the chances of an efficient diagnosis and repair.
Fully operational ignition starter motors and solenoids are often erroneously replaced because basic electrical components were not inspected first.
A vehicle with the B1363 trouble code may not be able to start, or it may have a difficult time starting. An inspection should be scheduled as soon as the code is detected.
Repairs for the B1363 trouble code include:
The B1363 code is a manufacturer specific trouble code, meaning that it only represents an ignition start circuit failure in certain vehicles. For some makes, the B1363 code has a different definition. Always take into account the vehicle that is being inspected when diagnosing this code.
