B17D5 Chrysler Code - Headlamp Status Output Circuit High

Quick Answer

The B17D5 diagnostic trouble code (DTC) is specific to Chrysler vehicles and indicates a fault in the headlamp status output circuit. Common causes include Wiring Issues: Damaged or frayed wiring in the headlamp circuit can lead to high voltage readings, Corroded Connectors: Corrosion at electrical connectors can create resistance, causing the BCM to misinterpret the headlamp status, Faulty BCM: A malfunctioning body control module may incorrectly report the headlamp status. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code B17D5 Chrysler Description

The B17D5 diagnostic trouble code (DTC) is specific to Chrysler vehicles and indicates a fault in the headlamp status output circuit. This code signifies that the vehicle's body control module (BCM) has detected a high voltage condition in the circuit responsible for monitoring the headlamp status. The headlamp status output circuit is crucial for the vehicle's lighting system, as it communicates the operational status of the headlamps to various control modules, including the BCM and the powertrain control module (PCM).

Common Causes of B17D5 Chrysler

  1. Wiring Issues: Damaged or frayed wiring in the headlamp circuit can lead to high voltage readings.
  2. Corroded Connectors: Corrosion at electrical connectors can create resistance, causing the BCM to misinterpret the headlamp status.
  3. Faulty BCM: A malfunctioning body control module may incorrectly report the headlamp status.
  4. Short Circuits: A short circuit within the headlamp circuit can lead to excessive voltage being detected.
  5. Aftermarket Modifications: Non-OEM parts or modifications to the headlamp system can disrupt the normal operation of the circuit.

Symptoms of B17D5 Chrysler

  1. Erratic Headlamp Operation: Headlights may flicker or fail to illuminate properly.
  2. Dashboard Warning Lights: The vehicle may display warning lights related to the lighting system.
  3. Inconsistent High Beam Activation: High beams may activate unexpectedly or fail to engage.
  4. BCM Malfunction: Other electrical components may exhibit erratic behavior due to the BCM's inability to manage headlamp status.
  5. Increased Battery Drain: A high voltage condition may lead to excessive power draw, affecting battery performance.

How to Fix B17D5 Chrysler

  1. Visual Inspection: Begin with a thorough visual inspection of the headlamp wiring and connectors for signs of damage or corrosion.
  2. Test Voltage Levels: Use a multimeter to check voltage levels in the headlamp circuit, ensuring they are within manufacturer specifications.
  3. Repair or Replace Wiring: If damaged wiring or corroded connectors are found, repair or replace them as necessary to restore proper function.
  4. BCM Diagnostics: If wiring appears intact, perform diagnostics on the BCM to determine if it is functioning correctly or needs replacement.
  5. Clear Codes and Test Drive: After repairs, clear the DTCs and take the vehicle for a test drive to ensure the issue has been resolved and the code does not return.

Cost to Fix B17D5 Chrysler

The cost to repair the B17D5 code can vary widely based on the specific issue identified. On average, repairs may range from $100 to $600, depending on whether it involves simple wiring repairs or a more complex BCM replacement. Labor costs typically range from $80 to $150 per hour, with metropolitan areas and dealerships often charging higher rates. Independent shops may offer lower rates.
