Circuit/System Testing



1. Verify that DTC P0562 is not set.



瀚慖f DTC P0562 is set, refer to Diagnostic Trouble Code (DTC) List - Vehicle (See: Diagnostic Trouble Code Descriptions/Diagnostic



Trouble Code (DTC) List - Vehicle).



2. Ignition OFF, disconnect the harness connector of the K27 fuel pump control module.



3. Ignition ON, verify that a test lamp illuminates between the ignition circuit terminal 21 and ground.



瀚慖f the test lamp does not illuminate, test the ignition circuit for a short to ground or an open/high resistance.



4. If all circuits test normal, replace the K27 fuel pump control module.
