The problem
CORROSIVE DAMAGE AND INCREASED ELECTRICAL RESISTANCE MAY CAUSE THE FUEL PUMP RELAY TO STOP FUNCTIONING. THE FUEL PUMP RELAY IS ONE OF SEVERAL RELAYS ON A RELAY BOARD LOCATED NEAR THE FIREWALL. CORROSION CAUSED BY RAIN ENTERING AN IMPROPERLY SEALED ANTENNA HOLE HAS BEEN THE SUBJECT OF PREVIOUS CAMPAIGNS, BUT ADDITIONAL MEASURES ARE REQUIRED TO ENSURE THAT THE PROBLEM IS CORRECTED.
What owners should do
VEHICLES WILL BE INSPECTED TO DETERMINE WHETHER THE MODIFICATION HAS BEEN PERFORMED. IF NOT, A BYPASS WILL BE INSTALLED TO LOCATE THE FUEL PUMP RELAY AWAY FROM THE RELAY BOARD. ANY CORRODED RELAY BOARDS OR CONNECTORS WILL ALSO BE REPLACED.
