Is Your Captiva Sport Running Rough, Stalling, or Refusing to Start?
As a technician with over two decades of experience under the hood, I’ve seen countless drivers frustrated by elusive engine problems. A flickering check engine light, unexplained stalling, poor fuel economy, or a complete no-start condition can often be traced back to a single, critical component: the Engine Control Module (ECM). Your 2012 Captiva Sport ECM is the brain of your vehicle, and when it fails, it can cause a cascade of confusing and costly issues.
From the Shop Floor: “A customer’s 2012 Captiva Sport came in last week with a persistent P0606 (ECM Processor Fault) code that wouldn’t clear, accompanied by intermittent stalling at stoplights. After meticulously checking the power and ground circuits to the moduleโa step many people skipโwe confirmed an internal ECM failure. Swapping in a pre-programmed module like this one resolved all the symptoms and had them back on the road the same day, completely avoiding a tow and lengthy wait at the dealership.”

Forget the hassle and expense of a dealership visit. This ECM, part number 12637106, is the reliable, straightforward solution you need. We take the guesswork out of the repair by programming the module specifically for your vehicle using your VIN.

Common Symptoms of a Failing 2012 Captiva Sport ECM:
- โ Persistent Check Engine Light (CEL) with communication codes (U-codes) or internal processor faults (P06xx codes).
- โ Engine stalling or shutting off while driving.
- โ Complete no-start condition where the engine cranks but won’t fire.
- โ Noticeable decrease in fuel efficiency.
- โ Harsh or erratic automatic transmission shifting.
- โ Misfires or rough idling that can’t be traced to plugs, coils, or injectors.
Plug-and-Play Installation: No Dealer Visit Required
Installing your new ECM is a job you can tackle with basic hand tools. For the 2012 Captiva Sport, the ECM is typically located in the left-hand (driver’s side) engine compartment. Follow these steps for a successful replacement:
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait at least 15 minutes for the system capacitors to discharge.
- Locate the ECM: Find the module on the driver’s side of the engine bay. It will have several large electrical connectors attached.
- Disconnect Connectors: Carefully release the locking tabs on each electrical harness connector and pull them straight out from the module. Never force them. Inspect the pins for any corrosion or damage.
- Remove the Old Module: Unbolt the old ECM from its mounting bracket.
- Install the New Module: Bolt your new, pre-programmed ECM into place.
- Reconnect Everything: Firmly seat the electrical connectors until they click, and then re-engage the locking tabs. Reconnect your negative battery terminal.
- Final Step: In many cases, a security relearn procedure may be required, which can typically be done without special tools. A common method is to turn the key to the ‘ON’ position for 10-15 minutes, then ‘OFF’ for 10 seconds, and repeat this cycle three times before attempting to start the vehicle.
