CHECK for TRCM system voltage low or TRCM motor DTCs. CHECK for selector lever cable bound, pinched or misrouted. REFER to: Selector Lever Cable Adjustment . PERFORM a network test. If CAN DTCs are present, follow the diagnostic procedure for those DTCs.
P07E6 Stuck In Park The shift by wire system commanded another gear than Park. After a period of time the TR sensor is valid but does not indicate Drive. The wrench light illuminates and a Shift System Fault message is displayed in the message center. Possible engine No Crank condition. No drive engagement. CHECK for TRCM system voltage low or TRCM motor DTCs. CHECK for selector lever cable bound, pinched or misrouted. REFER to: Selector Lever Cable Adjustment . PERFORM a network test. If CAN DTCs are present, follow the diagnostic procedure for those DTCs).
P0815 Upshift Switch Circuit GO to Pinpoint Test A
P0816 Downshift Switch Circuit GO to Pinpoint Test A
P085D Gear Shift Control Module "A" Performance This DTC alone indicates an issue with the redundant communication wire between the GSM and PCM. Perform the network test. If DTC P085D returns, GO to Pinpoint Test H
P0861 Gear Shift Control Module "A" Communication Circuit Low This DTC alone indicates an issue with the redundant communication wire between the GSM and PCM. Perform the network test. If DTC (diagnostic trouble code) P861 returns, GO to Pinpoint Test H
P0862 Gear Shift Control Module "A" Communication Circuit High This DTC alone indicates an issue with the redundant communication wire between the GSM and PCM. Perform the network test. If DTC P861 returns, GO to Pinpoint Test H
P164E Internal Control Module Transmission Range Performance CLEAR the DTC. PERFORM the GSM self-test. If the DTC returns, INSTALL a new GSM. REFER to: Gear Shift Module (GSM) .
P175B TRCM Shift Cable Disconnected / Misadjusted The shift by wire system commanded a range change and the EPB is applied without operator request. VERIFY the selector lever cable is securely connected. PERFORM the selector lever cable adjustment procedure, REFER to: Selector Lever Cable Adjustment .
P177F Unable To Fully Engage Neutral INSPECT the selector lever cable routing and adjustment. REFER to: Selector Lever Cable Adjustment . If the cable is adjusted correctly, apply the park brake and disconnect selector lever cable from the manual control lever. Manually move the manual control lever from Park to Drive and back to Park. If there is little or no resistance, INSPECT the manual valve detent spring. If the manual lever has excessive resistance or sticks then further investigation is required. If any low battery voltage DTCs are present RESOLVE them first. REPAIR any TRCM DTCs, if the concern still exists INSTALL a new TRCM. REFER to: Transmission Range Control Module (TRCM) .
U0103 Lost Communication With Gear Shift Control Module A If DTCs P085D, P0860, P0861, U101E and/or U101F are present, diagnose those DTCs first. PERFORM the Network Test, if the network test fails, REFER to module does not respond to the scan tool, REFER to: Communications Network . Otherwise, if DTC U0103 is the only DTC present, GO to Pinpoint Test J
U019E Lost Communication With Transmission Range Control Module If DTC P07F5, U101E and/or U101F are present, diagnose those DTCs first. PERFORM the Network Test. If the TRCM fails the network test, REFER to: Communications Network . Otherwise, if DTC U019E is the only DTC present, GO to Pinpoint Test O
U0155 Lost Communication With Instrument Panel Control Module GO to Pinpoint Test N
U0404 Invalid Data Received from Gear Shift Control Module "A" This DTC indicates the PCM is able to receive GSMCAN messages but the GSM is indicating a fault on one or more of the data signals that the TRCM uses for function. Using the diagnostic scan tool, retrieve GSM DTCs. REFER to DTC Chart - GSM and follow the GSM repair procedures.
U049F Invalid Data Received From Transmission Range Control Module This DTC indicates the PCM is able to receive TRCMCAN messages but the TRCM is indicating a fault on one or more of the data signals the GSM uses for function. Using the diagnostic scan tool, retrieve TRCM DTCs. REFER to DTC Chart - TRCM and follow the TRCM repair procedures.
U101E Invalid Internal Control Module Monitoring Data Received from Gear Shift Module Using a diagnostic scan tool, CONFIRM that both the PCM and GSM have the correct software level. If OK, PERFORM a network test on the gateway module. If the gateway module fails the network test, REFER to: Communications Network . Otherwise, CLEAR the DTCs and if any communication DTCs are retrieved RESOLVE them first. REFER to: Automatic Transmission - 2.0L EcoBoost (177kW/240PS) - MI4 . REFER to: Automatic Transmission - 2.3L EcoBoost (201kW/273PS) . If the DTC U101E returns alone, INSTALL a new GSM. REFER to: Gear Shift Module (GSM) .
U101F Invalid Internal Control Module Monitoring Data Received from Transmission Range Control Module Using a diagnostic scan tool, CONFIRM that both the PCM and TRCM have the correct software level. If OK, PERFORM a network test on the gateway module. If the gateway module fails the network test, REFER to: Communications Network . Otherwise, CLEAR the DTCs and if any communication DTCs are retrieved RESOLVE them first. REFER to: Automatic Transmission - 2.0L EcoBoost (177kW/240PS) - MI4 . REFER to: Automatic Transmission - 2.3L EcoBoost (201kW/273PS) . If the DTC U101F returns alone, INSTALL a new TRCM. REFER to: Transmission Range Control Module (TRCM) .
