DTC P1845 - TORQUE LIMIT MANAGEMENT

CIRCUIT DESCRIPTION
This diagnostic trouble code (DTC) may set if there is an engine torque limitation caused by requested torque higher than the maximum allowable torque.

DTC DESCRIPTOR
This diagnostic procedure supports the following DTC:
DTC P1845 Torque Limit Management

CONDITIONS FOR RUNNING THE DTC
The engine speed is more than 40 RPM.

CONDITIONS FOR SETTING THE DTC
The engine torque output exceeds a maximum allowable torque for 10 minutes.

ACTION TAKEN WHEN THE DTC SETS
- The control module illuminates the malfunction indicator lamp (MIL) on the second consecutive ignition cycle that the diagnostic runs and fails.
- The control module records the operating conditions at the time the diagnostic fails. The first time the diagnostic fails, the control module stores this information in the Failure Records. If the diagnostic reports a failure on the second consecutive ignition cycle, the control module records the operating conditions at the time of the failure. The control module writes the operating conditions to the Freeze Frame and updates the Failure Records.

CONDITIONS FOR CLEARING THE MIL/DTC
- The control module turns OFF the malfunction indicator lamp (MIL) after 4 consecutive ignition cycles that the diagnostic runs and does not fail.
- A current DTC, Last Test Failed, clears when the diagnostic runs and passes.
- A history DTC clears after 40 consecutive warm-up cycles, if no failures are reported by this or any other emission related diagnostic.
- Clear the MIL and the DTC with a scan tool.
