WARNING: This page is about a different variant/trim than selected.
Refer to TRANSMISSION CONTROLS - 6F50/6F55 or schematic and connector information.
Normal Operation and Fault Conditions
The TRCM receives two voltage inputs from the BJB. The hot in start and run fuse 23 (15A) circuit powers the TRCM micro processor. The hot at all times fuse 83 (20A) circuit powers the motors in the TRCM that are used to move the selector lever cable and the transmission manual valve inside the main control valve body.
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| P07F5 | Transmission Range Control Module System Voltage Low | The TRCM monitors the two voltage inputs for low or no power. When the voltage drops below a calibrated threshold, the TRCM sets the DTC. |
