Description:

Error code ECU 000655.06 is set when the ECU detects a short circuit in the electronic injector for cylinder no. 5, resulting in resistance that is too low. This condition typically indicates a short to ground.

Reaction:

The ECU may disable the injector to prevent damage and alert the operator of the fault.

Recommendations:

• Inspect for Short Circuits: Check the wiring and connectors for the injector in cylinder no. 5 for signs of short circuits to ground or other conductive surfaces.
• Measure Circuit Resistance: Use diagnostic tools to measure the resistance in the injector circuit and locate the short.
• Repair or Replace Damaged Wiring: Fix any identified short circuits by repairing or replacing faulty wiring or connectors.
• Verify Injector Operation: After repairs, test the injector to ensure it functions correctly and the short circuit issue is resolved.
• Reset ECU and Conduct System Tests: Reset the ECU and perform tests to confirm that the injector operates correctly and no further errors are detected.

Note:

Proper maintenance of injector wiring and connections is essential to avoid short circuits and ensure reliable engine performance.
