Fuel Injector Control Module Relay Control

Where it lives

For P0612, the part to look at first is the relay named here.

Check these first

• A failed injector control module relay
• A short or open in the relay control wire
• Corrosion at the relay connector
• A weak battery or low charging voltage
• A faulty ECM relay driver

What to do next

1. Check the relay and its fuse
2. Inspect the relay connector and control wire
3. Swap in a known good relay and retest
4. Measure the control wire for an open or short
5. Repair the relay control circuit if the fault stays
6. Clear the code and retest
