The graphic below shows the voltage related ...Code 097: This code, found in vehicles like the 2009 Volvo S80 D5, reflects a more specific engine system issue requiring further investigation. Once you’ve identified the problem codes, you can address the issues with greater precision.3. Check for multiple codes. Are codes SPN 4334/FMI 3, 4, SPN 4375/FMI 3, 4, or SPN 3361/FMI 3, 4, 5 also present? a. Yes; diagnose and repair the other fault codes first. Verify repair. b. No; Go to step 4. 4. Compare the AS110: ADS DEF pressure 2 reading to the barometric pressure sensor reading. Are the readings within 5 psi of each other? a.If you can access codes from the RCM, then the U010E code is either intermittent or a memory code. If unable to access the RCM, then the U010E code that the other modules are setting is active, and the problem is there now. The most common failure is a circuit fault which causes the loss of power or ground to the reductant control module.This pattern of codes indicates that there are issues with the ACM power supply or ground connections. Typically, this combination develops over time as a connection deteriorates. Eventually the effective voltage to the ACM drops below 8V and there is insufficient power to support the sensors controlled by the ACM - NOx, PM and DEF level/temp ...Turn the Ignition ON and recheck for the fault code.
