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.
