Checking Diagnostic Trouble Codes (DTCS) In The Engine Control Module (ECM)

WARNING: This page is about a different car, the 2007 Volvo XC90, 2006 Volvo XC90, 2005 Volvo XC90, 2004 Volvo XC90, and 2003 Volvo XC90. However, it is still accessible from the selected car via links, so may be relevant.

The diagnostic trouble code (DTC) is stored because the torque signal or engine speed signal from the engine has been missing for more than 500 ms. The signals are used by the brake control module for control the stability function.

If there are any diagnostic trouble codes (DTCs) stored for the engine control module (ECM), these must be fault traced first.

Were diagnostic trouble codes (DTCs) for the engine control module (ECM) stored?
