P0695Fan 3 Control Circuit Low
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Needs a drive cycle to confirm a fix
- How the car detects it
- The engine module switches the radiator fan relays (or the input of a PWM fan module) through output drivers and checks each control circuit electrically. GM sets a short to ground or voltage at 0.5 Ω or less after 50 of 63 samples, with the lamp after two trips; GM Europe's 2011 Saab 9-5 covers P0691–P0696 with relay assignments, the Saab 9-4X's PWM fan module reacts within 1 s. P0695 means the fan 3 control circuit is shorted to ground. Only the Saab page describes it in detail; GM lists it only in collective tables without thresholds.
- What you may notice
- Check engine light (GM after two trips)
- Fan runs constantly or not at all, depending on circuit design
- Rising coolant temperature in traffic or with A/C on
- A/C may be switched off to protect the engine
- Likely causes
- LikelyControl wire to fan relay or module shorted to ground (chafing)
- LikelyWater or corrosion in fan or relay connector
- PossibleFan relay faulty (coil shorted or low-resistance)
- RareEngine module driver faulty
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
- Repair
- Easy · Often possible to do yourself.Typical cost: €20 – €400
