From the Shop Floor: A Real-World Diagnosis
“A customer’s 2011 SAAB 9-5 2.0L came into my shop last month with a classic case of ECM failure. The car would randomly stall at red lights and sometimes refuse to restart for 10-15 minutes. The dash was lit up with multiple, unrelated warning lights, and the scan tool showed a U0100 ‘Lost Communication with ECM’ code. Before jumping to conclusions, we checked the basics: battery voltage was strong, and we verified solid power and ground signals at the ECM connector. With the fundamentals confirmed, it was clear the internal circuitry of the original module was failing. We installed one of our pre-programmed ECMs, performed the simple 10-minute key relearn procedure, and the car fired up instantly. All ghost codes were gone, and the stalling issue was completely resolved. It’s a textbook repair I’ve seen dozens of times on these GM platforms.”

Plug-and-Play Installation: No Dealer Visit Required
You can get your SAAB back to peak condition right in your own driveway. Follow these simple steps for installation:
- Safety First: Disconnect the negative terminal from your car’s battery and wait 10 minutes for the systems to discharge.
- Locate the ECM: On the 2010-2011 SAAB 9-5, the Engine Control Module is typically located in the left-hand (driver’s side) of the engine compartment.
- Disconnect and Remove: Carefully unclip the wiring harness connectors. Be gentle with the locking tabs. Then, unbolt the module from its mounting bracket and remove it from the vehicle.
- Install the New Module: Bolt the new, pre-programmed ECM into place. Securely reconnect the wiring harnesses, ensuring they click into place.
- Reconnect Battery: Re-attach the negative battery terminal.
- Perform Security Relearn: Most vehicles using this ECM will require a simple key relearn. Turn the key to the ‘ON’ position for 10 minutes, then ‘OFF’ for 10 seconds. Repeat this cycle two more times (for a total of 30 minutes). The vehicle should then start and run normally.
