AFFECTED VEHICLES:
DESCRIPTION:
Volvo has found that only after long-term, reoccurring exposure to certain environmental conditions (salty-wet conditions) it is possible for the Pump Electronic Module (PEM) to become corroded internally.
This may cause a faulty signal to the fuel pump, resulting in low or no fuel pressure to the engine. If this occurs, the Malfunction Indicator Lamp (MIL) may illuminate. In some cases, the vehicle may fail to start or may stall increasing the risk of a crash.
Once this condition is confirmed the corrective action will be to replace the PEM and install in a new location to prevent corrosion.
Follow directions in this document.
NOTE:
In this document the PEM is referred to by fuel pump (FP) control module.
