DTC P183F
- Internal Mode Switch 1-2 Correlation
Diagnostic Fault Information
Typical Scan Tool Data
Circuit/System Description
The internal mode switch (IMS) assembly is a sliding contact switch attached to the control valve body within the transmission. 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
(HPCM). The input voltage at the module is high when the switch is open and low when the switch is closed to ground.
Conditions for Running the DTC
* Manual Shift Shaft Position Switch Replacement (See: Powertrain Management/Computers and Control Systems/Sensors and Switches -
Computers and Control Systems/Transmission Position Sensor/Switch/Service and Repair/2ML70 - Automatic Transmission).

DTC P183F
- Internal Mode Switch 1-2 Correlation
Diagnostic Fault Information
Typical Scan Tool Data
Circuit/System Description
The internal mode switch (IMS) assembly is a sliding contact switch attached to the control valve body within the transmission. 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
(HPCM). The input voltage at the module is high when the switch is open and low when the switch is closed to ground.
Conditions for Running the DTC
* Manual Shift Shaft Position Switch Replacement (See: Powertrain Management/Computers and Control Systems/Sensors and Switches -
Computers and Control Systems/Transmission Position Sensor/Switch/Service and Repair/2ML70 - Automatic Transmission).
