DTC Descriptor
DTC P1E00
- Hybrid Powertrain Control Module 2 Requested MIL Illumination

Circuit/System Description

This diagnostic trouble code (DTC) indicates that an emission related DTC has set in the hybrid powertrain control module 2. The hybrid powertrain control module 2 sends a message, via the serial data circuit, to the engine control module (ECM) requesting illumination of the malfunction indicator lamp (MIL). When the ECM receives the message, DTC P1E00 will set in the ECM.

Conditions for Running the DTC

The ignition is ON, or the engine is running for greater than 3 s.

Conditions for Setting the DTC

The hybrid powertrain control module 2 has set an emission related DTC.

Action Taken When the DTC Sets

* DTC P1E00 is a Type A DTC.
* DTC P1E00 will continue to be current or active as long as the hybrid powertrain control module 2 is requesting MIL illumination.

Conditions for Clearing the DTC

DTC P1E00 is a Type A DTC.

Diagnostic Aids

Communication codes, U-codes, as well as powertrain codes, P-codes, set in the hybrid powertrain control module 2 will cause the hybrid powertrain control module 2 to request DTC P1E00 to be set in the ECM.

Circuit/System Verification

Note: Correct any engine controls and communication DTCs before diagnosing hybrid powertrain control module 2 DTCs.

1. DTC P1E00 is an informational DTC. If there are no other engine controls or communication DTCs set, refer to Diagnostic Trouble Code (DTC) List - Vehicle Diagnostic Trouble Code (DTC) List - Vehicle for diagnosis of hybrid powertrain control module 2 DTCs.
2. Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.
