DTC Descriptor
DTC P183F
- Internal Mode Switch 1-2 Not Plausible

Circuit/System Description

The internal mode switch assembly is a sliding contact switch attached to the control valve body within the transmission. The internal mode switch is integrated into the Manual Shift Shaft Position Switch and is not serviced separately. The nine outputs from the switch indicate which position is selected by the transmission manual shaft. Four outputs (A, B, C, P), are range selection inputs to the transmission control module (TCM). Five outputs (R1, R2, D1, D2, S) are direction selection inputs to the hybrid powertrain control module. The hybrid powertrain control module compares the internal mode switch requested direction to the range switch to verify that the indicated direction calculation is correct.

The hybrid powertrain control module is internal to the power inverter module, often referred to as the drive motor generator power inverter module, and is not serviced separately.

Circuit/System Verification

1. Verify that DTC P181C, P181D, P181E, P181F, P183A, P183B, P183C, P183D, P183E, P184A or P184B is not set.

• If any of the DTCs are set, refer to DTC P181C-P181F, P183A-P183E, P184A, or P184B P181C.

2. Verify that DTC P183F is not set.

• If the DTC is set, program the hybrid powertrain control module. If the DTC resets, replace the T6 power inverter module.
