S40T5 2004 EMISSIONS

Post by rchart »

This car has communication with our Modus but no communication at emissions so it fails.No codes ,I talked to a Volvo dealer to see if it would be covered under the emissions warranty they said only cats and ECM are covered.I checked the wires from diag connector to CEM (under glove box).They ohmed out good.I don't have a good diagram to trace wires from CEM to ECM. Any help would be greatly appreciated.Emissions in Ct. just use obdII system.Ron
