TSB 22-2490 - Shift System Fault, Unable to Engage Park, P07E4 Code in SOBDMC

[Mach-Lee]

This issue is rare, but I've seen it a couple times. Shifting into park may fail with a "Shift System Fault" error message and the vehicle may continue to roll (apply the parking brake and turn off the vehicle). The error will most likely be gone the next time the vehicle is turned on. A P07E4 code will be stored in the SOBDMC (rear motor). Turns out this is just a software glitch, the fix is updating the powertrain software. It does not mean the park pawl is bad or requires replacement (which is a major mechanical teardown).

TECHNICAL SERVICE BULLETIN Illuminated Powertrain Malfunction (Wrench) Indicator With DTC P07E4 Stored in the SOBDMC - Built On Or Before 14-Sep-2022	22-2490 15 December 2022​
Model: Ford 2021-2022 Mustang Mach-E Built on or before 14-Sep-2022 Markets: Canada, USA Issue: Some 2021-2022 Mustang Mach-E vehicles built on or before 14-Sep-2022 may exhibit an illuminated powertrain malfunction (wrench) indicator with diagnostic trouble code (DTC) P07E4:00 stored in the secondary on-board diagnostic control module C (SOBDMC) and/or unable to engage park (P). This may be due to the software in the SOBDMC. To correct this condition, follow the Service Procedure to reprogram the powertrain control module (PCM). Action: Follow the Service Procedure to correct the condition on vehicles that meet all of the following criteria: • 2021-2022 Mustang Mach-E vehicles • Built on or before 14-Sep-2022 • One or more of the following conditions: - Illuminated powertrain malfunction (wrench) indicator with DTC P07E4:00 stored in the SOBDMC - Unable to engage park (P) Warranty Status: Eligible under provisions of New Vehicle Limited Warranty (NVLW)/Emissions Warranty/Service Part Warranty (SPW)/Special Service Part (SSP)/Extended Service Plan (ESP) coverage. Limits/policies/prior approvals are not altered by a TSB. NVLW/Emissions Warranty/SPW/SSP/ESP coverage limits are determined by the identified causal part and verified using the OASIS part coverage tool. Labor Times Description Operation No. Time 2021-2022 Mustang Mach-E: Reprogram The Appropriate Modules As Required By The Software Update And Service Procedure (Do Not Use With Any Other Labor Operations) MT222490​ Actual Time​ Repair/Claim Coding Causal Part: RECALEM Condition Code: 04 Service Procedure 1. Connect a battery charger to the 12-volt battery. NOTE: To prevent the battery saver mode from activating on the vehicle, make sure the negative cable of the charger is installed on a chassis or engine ground, and not the 12-volt battery negative terminal. Do not have the vehicle plugged into the high voltage battery charger during programming. This can cause incorrect module programming. Make sure only the 12-volt battery charger is installed. 2. Reprogram the PCM using the latest software level of the Ford Diagnosis and Repair System (FDRS) scan tool. 3. Check the availability of software updates on the following modules and update as required: (1). Secondary on-board diagnostic control module (SOBDM) (2). Battery energy control module (BECM) (3). Secondary on-board diagnostic control module B (SOBDMB) (4). Secondary on-board diagnostic control module C (SOBDMC) (5). Anti-lock brake system (ABS) module NOTE: Only one module may be updated at a time. 4. Verify proper park engagement and disengagement. If park engagement and disengagement do not work properly, follow normal diagnostics outside of the article.
