B17D2 Chrysler Code - Emergency Flashing Lamp Request 2 Circuit High
Quick Answer
The B17D2 diagnostic trouble code (DTC) is specific to Chrysler vehicles and indicates a problem with the Emergency Flashing Lamp Request 2 circuit, which is registering a high voltage condition. Common causes include Short Circuit: A short in the wiring harness can cause excessive voltage to be sent to the BCM, Faulty BCM: A malfunctioning body control module may misinterpret normal voltage levels as high, Corroded Connectors: Corrosion at connectors can lead to poor electrical connections, causing erratic voltage readings. 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 B17D2 Chrysler Description
The B17D2 diagnostic trouble code (DTC) is specific to Chrysler vehicles and indicates a problem with the Emergency Flashing Lamp Request 2 circuit, which is registering a high voltage condition. This code is part of the body control module (BCM) system, which manages various electrical functions in the vehicle, including the operation of the emergency flashers. When the BCM detects that the voltage in the Emergency Flashing Lamp Request 2 circuit exceeds the expected range, it triggers this code.
Common Causes of B17D2 Chrysler
- Short Circuit: A short in the wiring harness can cause excessive voltage to be sent to the BCM.
- Faulty BCM: A malfunctioning body control module may misinterpret normal voltage levels as high.
- Corroded Connectors: Corrosion at connectors can lead to poor electrical connections, causing erratic voltage readings.
- Damaged Wiring: Frayed or damaged wires can create resistance in the circuit, leading to voltage spikes.
- Aftermarket Modifications: Installation of aftermarket electrical components may inadvertently affect the BCM's operation.
Symptoms of B17D2 Chrysler
- Inoperative Emergency Flashers: The emergency flashers may not activate at all, or they may operate intermittently.
- Dashboard Warning Lights: The vehicle may display warning lights related to the BCM or electrical system.
- Erratic Behavior of Other Electrical Components: Other systems controlled by the BCM, such as turn signals or interior lights, may function improperly.
- Increased Battery Drain: A malfunctioning circuit can lead to excessive power draw, resulting in a drained battery.
- Overheating Components: Components related to the emergency flashing system may become excessively hot due to electrical issues.
How to Fix B17D2 Chrysler
- Visual Inspection: Begin with a thorough visual inspection of the wiring harness and connectors related to the Emergency Flashing Lamp Request circuit for signs of damage or corrosion.
- Test Voltage Levels: Use a multimeter to measure the voltage in the circuit to determine if it exceeds normal operating levels.
- Repair or Replace Damaged Wiring: If damaged wiring is found, repair or replace it to restore proper electrical flow.
- Check and Replace Connectors: Clean or replace corroded connectors to ensure a solid electrical connection.
- BCM Reprogramming or Replacement: If the BCM is determined to be faulty, it may need to be reprogrammed or replaced to resolve the issue.
Cost to Fix B17D2 Chrysler
The typical repair costs for addressing the B17D2 code can vary widely based on the specific diagnosis and repairs needed. On average, the cost may range from $150 to $600, depending on whether it involves simple wiring repairs or more complex BCM replacement. Labor rates at auto repair shops can fluctuate based on location, vehicle make and model, and engine type. Most shops charge between $80 and $150 per hour; however, rates in metropolitan areas or at dealerships may be higher, while independent shops often offer lower rates.
