This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer is having trouble controlling a switch that turns on important parts of the engine. It's like a light switch that isn't working right.
The P1697 code indicates that the voltage in the main relay control circuit is higher than expected, which can affect the operation of the vehicle's electrical systems.
The main relay is responsible for supplying power to the vehicle's engine control module (ECM) and other critical systems. A 'high' condition suggests that the relay circuit is receiving too much voltage, which could be due to a short circuit, a faulty relay, or wiring issues.
• Engine not starting
• Check Engine Light on
• Electrical systems malfunctioning
• Faulty main relay
• Short circuit in the wiring
• Faulty ECM
ECM: Engine Control Module
OBD-II: On-Board Diagnostics II
• Inspect the main relay for damage or corrosion.
• Check the wiring and connectors for shorts or open circuits.
• Test the ECM for proper operation.
• Replace the faulty main relay.
• Repair or replace damaged wiring.
• Replace the ECM if necessary.
• Multimeter
• OBD-II scanner
• Basic hand tools

Moderate
• Dodge Neon
• Jeep Grand Cherokee
• Chrysler PT Cruiser
• Regularly inspect electrical connections.
• Avoid exposure to moisture and corrosion.
• Perform routine vehicle maintenance.
Electrical Circuit Issue
• Do not ignore the Check Engine Light.
• Have the vehicle inspected by a professional.
• Avoid driving if the engine won't start.
Check with your vehicle manufacturer for warranty coverage on electrical components.
This code is commonly associated with Chrysler vehicles from the early 2000s.
Moderate – While the vehicle may still operate, it is recommended to address this issue promptly to avoid further electrical problems.
Driving with electrical issues can be unsafe. Ensure repairs are conducted by a qualified technician.
• Ensure the vehicle is on a flat surface.
• The engine should be off and cool before inspection.
The main relay is typically located in the vehicle's fuse box under the hood.
Q: Can I drive with a P1697 code?
A: It's not recommended to drive with this code as it can lead to further electrical issues.
Q: How do I reset the P1697 code?
A: After repairs, use an OBD-II scanner to clear the code. If the issue persists, further diagnosis is needed.
