October 30: LEMON manuals on a temporary server, it is slow and having issues, download the manuals you need! Later in November we will switch back to the fast server.
Circuit/System Testing
- Verify that DTC P0562 is not set.
- Ignition OFF, disconnect the harness connector of the K27 fuel pump control module.
- Ignition ON, verify that a test lamp illuminates between the ignition circuit terminal 21 and ground.
- If the test lamp does not illuminate, test the ignition circuit for a short to ground or an open/high resistance.
- If all circuits test normal, replace the K27 fuel pump control module.
