The P0696 code is an OBD-II trouble code indicating a problem with the Fan 3 control circuit in the vehicle’s electric cooling fan system. This system is crucial for maintaining optimal engine temperatures, especially under demanding conditions such as high ambient temperatures or when the air conditioning is operating.
What Does the P0696 Code Mean?
When the Engine Control Module (PCM) detects that the Fan 3 control circuit is operating at a higher voltage than expected, it triggers the P0696 code. This could prevent the cooling fan from functioning correctly, which can lead to engine overheating and other related issues.
What Causes the P0696 Code?
- Engine cooling fan control module failure
- Engine cooling fan failure
- Engine cooling fan relay failure
- Powertrain Control Module (PCM) failure
- Wiring issues within the circuit
What Are the Symptoms of the P0696 Code?
- Cooling fans may stay on continuously
- Engine may overheat
- A/C may not operate effectively
How Serious Is the P0696 Code?
The P0696 code is classified as urgent. Immediate action is necessary, as failure to address this issue can lead to severe engine damage or pose hazards to the driver and passengers due to overheating.
How to Diagnose the P0696 Code
Diagnosing the P0696 code involves several steps:
- Check for any additional trouble codes that may provide further context.
- Inspect the wiring and connectors associated with the cooling fan system for any signs of damage or corrosion.
- Test the cooling fan control module and relay for proper operation.
- Ensure the PCM is functioning correctly and is not at fault.
Common Repairs for the P0696 Code
- Radiator fan assembly replacement
- Repair or replacement of damaged wiring
- Replacement of the cooling fan relay
- Replacement of the cooling fan control module
