DTC P0611 | Fuel injector control module performance
--- | ---
DETECTION CONDITION | • When the PCM drives fuel injectors No.1-No.4 but the injector driver module No.1-No.4 circuit voltage is low, the PCM determines that there is a fuel injector control module performance problem. MONITORING CONDITION - The following conditions are met: • Battery voltage: 10.03 V or more • Fuel injection control: except during fuel cut Diagnostic support note • This is a continuous monitor (Other). • MIL does not illuminate. • FREEZE FRAME DATA is not available. • DTCs are stored in the PCM memory.
POSSIBLE CAUSE | • Injector driver module malfunction • Connector or terminal malfunction • Short to ground in the wiring harness between injector driver module terminal 2B and PCM terminal 3K • Short to ground in the wiring harness between injector driver module terminal 2C and PCM terminal 3H • Short to ground in the wiring harness between injector driver module terminal 2D and PCM terminal 3E • Short to ground in the wiring harness between injector driver module terminal 2E and PCM terminal 3B • PCM malfunction

Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | VERIFY FREEZE FRAME DATA AND DIAGNOSTIC MONITORING TEST RESULTS HAS BEEN RECORDED • Has FREEZE FRAME DATA been recorded? | Yes | Go to the next step.
No | Record the FREEZE FRAME DATA on the repair order, then go to the next step.
2 | VERIFY RELATED REPAIR INFORMATION AVAILABILITY • Verify related Service Information availability. • Is any related Service Information available? | Yes | Perform repair or diagnosis according to the available Service information. If the vehicle is not repaired, go to the next step.
No | Go to the next step.
3 | INSPECT INJECTOR DRIVER MODULE CONNECTOR FOR POOR CONNECTION • Turn the ignition switch off. • Disconnect the injector driver module connector. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Is there any malfunction? | Yes | Repair or replace the terminal, then go to Step 7.
No | Go to the next step.
4 | INSPECT INJECTOR DRIVER MODULE CIRCUIT FOR SHORT TO GROUND • Turn the ignition switch off. • Inspect for continuity between the following terminals. - Injector driver module terminal 2B (wiring harness-side) and body ground - Injector driver module terminal 2C (wiring harness-side) and body ground - Injector driver module terminal 2D (wiring harness-side) and body ground - Injector driver module terminal 2E (wiring harness-side) and body ground • Is there continuity? | Yes | Repair or replace the wiring harness for a short to ground, then go to Step 7.
No | Go to the next step.
5 | INSPECT INJECTOR DRIVER MODULE • Inspect the injector driver module. (See INJECTOR DRIVER MODULE INSPECTION [L3 Turbo].) • Is there malfunction? | Yes | Replace the injector driver module, then go to Step 7. (See INJECTOR DRIVER MODULE REMOVAL/INSTALLATION [L3 Turbo].)
No | Go to the next step.
6 | INSPECT PCM CONNECTOR FOR POOR CONNECTION • Turn the ignition switch off. • Disconnect the PCM connector. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Is there any malfunction? | Yes | Repair or replace the terminal, then go to the next step.
No | Go to the next step.
7 | VERIFY TROUBLESHOOTING OF DTC P0611 COMPLETED • Make sure to connect all disconnected connectors. • Clear the DTC from the PCM memory using the WDS or equivalent. • Start the engine. • Is the same DTC present? | Yes | Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [L3 Turbo].)
No | Go to the next step.
8 | VERIFY AFTER REPAIR PROCEDURE • Perform the "AFTER REPAIR PROCEDURE". (See AFTER REPAIR PROCEDURE [L3 Turbo].) • Are any DTCs present? | Yes | Go to the applicable DTC inspection. (See DTC TABLE [L3 Turbo].)
No | DTC troubleshooting completed.
