Troubleshooting Sequence
DTC 652.06
When DTC is Displayed
The engine is cranking or running and the error condition is active. The DTC may also be displayed during HARNESS
DIAGNOSTIC MODE TEST in Service ADVISOR, provided fuel rail pressure is below 725 psi (5 MPa).
Related Information
The ECU detects low resistance in the cylinder #2 electronic injector circuit.
The ECU has two internally-connected terminals, which provide a shared high voltage supply to all the injectors.
The ECU switches the low side (ground) to control each individual injector.
This DTC can be caused by a wire-to-wire short. A short between the low side wiring of two injectors will cause active
DTCs indicating low resistance in both injectors.
This DTC can also be caused by an injector that has low coil resistance (coil windings are shorted together).
