P1696 Chrysler Code - PCM EEPROM Fault Write Denied Conditions
Quick Answer
The P1696 Chrysler code indicates a PCM (Powertrain Control Module) EEPROM (Electrically Erasable Programmable Read-Only Memory) fault write denied condition. Common causes include Faulty PCM: The PCM itself may be defective, causing issues with writing data to the EEPROM, Electrical Problems: Issues with the vehicle's electrical system, such as a faulty wiring harness or loose connections, can disrupt communication with the PCM, Software Glitches: Software errors or corruption within the PCM's programming can prevent it from writing to the EEPROM. 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 P1696 Chrysler Description
The P1696 Chrysler code indicates a PCM (Powertrain Control Module) EEPROM (Electrically Erasable Programmable Read-Only Memory) fault write denied condition. In simpler terms, it means that there is an issue with the PCM's ability to write or save data to its memory. The PCM is a crucial component of the vehicle's engine control system, responsible for managing various functions such as fuel delivery, ignition timing, and emissions control.
Common Causes of P1696 Chrysler
- Faulty PCM: The PCM itself may be defective, causing issues with writing data to the EEPROM.
- Electrical Problems: Issues with the vehicle's electrical system, such as a faulty wiring harness or loose connections, can disrupt communication with the PCM.
- Software Glitches: Software errors or corruption within the PCM's programming can prevent it from writing to the EEPROM.
- Environmental Factors: Extreme temperatures, moisture, or other environmental factors can damage the PCM's memory storage.
Symptoms of P1696 Chrysler
- Check Engine Light: The most common symptom associated with this code is the illumination of the check engine light on the dashboard.
- Engine Performance Issues: The vehicle may experience poor acceleration, rough idling, hesitation, or stalling while driving.
- Reduced Fuel Efficiency: The engine may consume more fuel than usual due to the PCM's inability to optimize fuel delivery.
- Difficulty Starting: The vehicle may have difficulty starting or may fail to start altogether due to the PCM fault.
How to Fix P1696 Chrysler
- Diagnose the Issue: Use a diagnostic scan tool to retrieve the specific trouble code and determine the exact nature of the PCM EEPROM fault.
- Inspect Wiring and Connections: Check for any loose or damaged wiring connections that may be affecting communication with the PCM.
- Test the PCM: Perform tests to assess the functionality of the PCM and determine if it needs to be replaced.
- Repair or Replace PCM: Depending on the diagnosis, repair the existing PCM if possible, or replace it with a new or remanufactured unit.
- Clear Codes and Test Drive: Clear the diagnostic trouble codes from the PCM's memory, and take the vehicle for a test drive to ensure the issue has been resolved.
Cost to Fix P1696 Chrysler
The cost of repairing a PCM EEPROM fault can vary depending on the specific cause of the issue and the labor rates at the repair shop. In general, replacing a faulty PCM can range from $500 to $1000, including parts and labor. However, additional diagnostic time and troubleshooting may be needed, which could increase the overall repair cost. It's recommended to consult with a trusted mechanic or dealership for a more accurate estimate based on your vehicle's make and model.
