Recall - ECM Software Update for Fuel Pump Function

SAFETY RECALL: Engine Cut Out - 5.0L V8

AFFECTED VEHICLE RANGE:

CONDITION SUMMARY:

Situation:

A concern has been identified with 2010 model year Jaguar XF and 2010 - 2011 model year XK 5.0-liter V8 gasoline-engine vehicles whereby the

in-tank electric fuel pump may not be correctly activated as the fuel pump relay is not energized following a vehicle start-up cycle. As a result, it is

possible that the engine may start and continue to operate as normal for a variable period of time until the engine fuel demand exceeds the ability for

the high pressure fuel pump to supply fuel. The engine can then cut out without any detectable warning signs. Fuel starvation to the engine leads to

engine stumble followed by engine cut out with minimal warning and could potentially cause a crash.

After engine cut out, once the brake vacuum reservoir is depleted the vehicle will lose brake power assistance; however, foundation brakes continue

to operate. Power Assisted Steering (PAS) will be lost once the vehicle speed drops below the torque converter speed threshold; however, the

vehicle steering will remain functional but with increased steering effort required. The customer will need to cycle the ignition to re-engage the fuel

pump relay.

To overcome the affects of the fuel pump not being activated correctly, Jaguar has released revised vehicle software that ensures that when the

engine is running the in-tank fuel pump relay remains energized.
