1.
|
Verify that DTC P0562 is not set.
|
3.
|
Ignition OFF, disconnect the harness connector of the K27 fuel pump control module.
|
4.
|
Ignition ON, verify that a test lamp illuminates between the ignition circuit terminal 21 and ground.
|
5.
|
If the test lamp does not illuminate, test the ignition circuit for a short to ground or an open/high resistance.
|
6.
|
If all circuits test normal, replace the K27 fuel pump control module.
