The FIAT B1017-15 code is a diagnostic trouble code (DTC) associated with the Central High Mounted Stop Light Circuit. The code occurs when the Body Control Module (BCM) detects an issue with the Stop Lamp Switch, the output circuits for the Left and Right Tail Lamp Assemblies, or the CHMSL. Common causes for the code include BRAKE LAMP SWITCH OUTPUT CIRCUIT SHORTED TO VOLTAGE, BRAKE LAMP SWITCH OUTPUT CIRCUIT OPEN, GROUND CIRCUIT OPEN, CENTER HIGH MOUNTED STOP LAMP (CHMSL) BULB, and BODY CONTROL MODULE (BCM). The FIAT B1017-15 code is Circuit Short To Battery or Open, a type of failure where the condition detected by the control module is the same for either failure mode.

BRAKE LAMP SWITCH OUTPUT CIRCUIT SHORTED TO VOLTAGE
The first cause of this code is a BRAKE LAMP SWITCH OUTPUT CIRCUIT SHORTED TO VOLTAGE. This occurs when the stop lamp switch is malfunctioning or damaged and must be replaced or repaired.
BRAKE LAMP SWITCH OUTPUT CIRCUIT OPEN
The second cause of the code is a BRAKE LAMP SWITCH OUTPUT CIRCUIT OPEN. This occurs when the wiring harness is damaged and must be replaced or repaired.
GROUND CIRCUIT OPEN
The third cause of the code is a GROUND CIRCUIT OPEN. This occurs when the ground circuit has been damaged and must be replaced or repaired.
CENTER HIGH MOUNTED STOP LAMP (CHMSL) BULB
The fourth cause of this code is a CENTER HIGH MOUNTED STOP LAMP (CHMSL) BULB malfunction. If the CHMSL bulb is malfunctioning, it will need to be replaced.
BODY CONTROL MODULE (BCM)
The last cause of this code is a BODY CONTROL MODULE (BCM) malfunction. If the BCM is malfunctioning, it will need to be replaced.
Conclusion
The FIAT B1017-15 Code is a diagnostic trouble code associated with the Central High Mounted Stop Light Circuit. This code is triggered when the Body Control Module (BCM) identifies an issue with the Stop Lamp Switch or the output circuits of the Left and Right Tail Lamp Assemblies and Centered High Mounted Stop Lamp. The causes of the FIAT B1017-15 Code can range from a BRAKE LAMP SWITCH OUTPUT CIRCUIT SHORTED TO VOLTAGE, BRAKE LAMP SWITCH OUTPUT CIRCUIT OPEN, GROUND CIRCUIT OPEN, CENTER HIGH MOUNTED STOP LAMP (CHMSL) BULB and BODY CONTROL MODULE (BCM) malfunction.
