ECM Programming

When replacing Transmission Module (TM) or Engine Control Module (ECM), use Volvo System Tester to clear DTCs and reset adaptive functions. Follow manufacturer's instructions and tester prompts.

After disconnecting battery or replacing ECM, drive vehicle to enable ECM to relearn driveability. Inform your customer that he/she may experience driveability different from what they are accustomed to until ECM completes relearn function.
