P1696 Dodge Code - PCM EEPROM Fault Write Denied Conditions
Quick Answer
The P1696 Dodge code indicates a PCM (Powertrain Control Module) EEPROM Fault Write Denied Conditions. Common causes include Faulty Wiring: Damage or corrosion to the wiring harness connecting the PCM to the EEPROM, PCM Malfunction: Internal PCM issues preventing data writing to the EEPROM, Electrical Interference: External factors causing interference with the PCM's communication. 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 Dodge Description
The P1696 Dodge code indicates a PCM (Powertrain Control Module) EEPROM Fault Write Denied Conditions. The PCM is a critical component of a vehicle's engine management system, responsible for controlling various functions such as fuel delivery, ignition timing, and emissions control. The EEPROM (Electrically Erasable Programmable Read-Only Memory) is a type of memory storage used by the PCM to store vital information and calibration data.
Common Causes of P1696 Dodge
- Faulty Wiring: Damage or corrosion to the wiring harness connecting the PCM to the EEPROM.
- PCM Malfunction: Internal PCM issues preventing data writing to the EEPROM.
- Electrical Interference: External factors causing interference with the PCM's communication.
- Software Glitch: Programming errors or glitches in the PCM software affecting EEPROM writing.
- Battery Voltage Fluctuations: Inconsistent voltage supply to the PCM can disrupt data writing processes.
Symptoms of P1696 Dodge
- Check Engine Light: The most common symptom associated with this code is the illumination of the Check Engine Light on the dashboard.
- Poor Engine Performance: The vehicle may experience rough idling, hesitation, or lack of power during acceleration.
- Starting Issues: Difficulty starting the engine or prolonged cranking before the engine starts.
- Reduced Fuel Efficiency: The vehicle may consume more fuel than usual due to incorrect fuel delivery.
- Transmission Issues: Shift irregularities or erratic transmission behavior may occur as a result of the PCM fault.
How to Fix P1696 Dodge
- Diagnose Fault: Use a diagnostic scanner to retrieve the specific fault code and determine the underlying cause of the PCM EEPROM fault.
- Check Wiring: Inspect the wiring harness for any damage, corrosion, or loose connections. Repair or replace as needed.
- Test PCM: Perform tests to check the functionality of the PCM and ensure it can communicate with the EEPROM.
- Reprogram PCM: If necessary, reprogram the PCM with the latest software updates to address any software glitches.
- Replace PCM: In severe cases where the PCM is malfunctioning, it may need to be replaced to resolve the EEPROM fault.
Cost to Fix P1696 Dodge
The typical repair costs for addressing a P1696 Dodge code can vary depending on the specific cause of the fault and the required repairs. In general, the cost of parts for wiring repairs or reprogramming the PCM can range from $100 to $500 or more. Labor costs at auto repair shops typically range from $80 to $150 per hour, and the total repair cost can amount to several hundred dollars or more.
