Is this intermittent or permanent? Does it return immediately after clearing? Troubleshooting Done So Far:
Likely a scam listing or a parts catalog error. Avoid. Use verified part numbers and trusted suppliers instead.
Identifying the root cause is the first step to a correct repair. The B109C15 code is triggered by:
Land Rovers are built to handle extreme environments, but age, vibration, and environmental factors can compromise electrical integrity over time. 1. Wiring Harness Chafing
Understanding the Land Rover B109C-15 Diagnostic Trouble Code
Temporary software glitches in the Door Module (DDM or PDM). Troubleshooting and Fixes The "Reboot" Trick:
For this step, you will need a basic .
In standard OBD-II sub-coding, a hexadecimal sub-type "15" explicitly denotes an Open Circuit or a Short Circuit to Battery (+B) . This means the control unit is either seeing infinite electrical resistance (a severed wire or unplugged motor pin) or detecting system voltage on a signal return line where it shouldn't be. 2. Common Symptoms in Land Rover Models
When this code sets, the Central Junction Box (CJB) or Body Control Module (BCM) has detected either a complete break in the wire (open circuit) or a situation where power is leaking into the signal line from a outside voltage source (short to battery). Common Symptoms
