202291 TECHNICAL SERVICE BULLETIN Reverse Braking Assist Perceived As Too Sensitive Detecting Objects - Built On Or Before 23-July-2020 28 August 2020 This bulletin supersedes 20-2135 . Reason for update: Incorrect Procedure Model: Ford 2020 Explorer Lincoln 2020 Aviator 2020 Corsair Summary This article supersedes TSB 20-2135 to correct the Service Procedure. Issue: Some 2020 Explorer/Aviator/Corsair vehicles built on or before 23-Jul-2020 may inadvertently activate the reverse braking assist system while backing up. This may be perceived as the system is too sensitive to surrounding objects. This may be due to the software in the image processing module B (IPMB). To correct the condition, follow the Service Procedure to reprogram the IPMB, as well as the accessory protocol interface module (APIM) to allow the vehicle to remember the last setting of reverse brake assist when the vehicle is restarted. Action: Follow the Service Procedure to correct the condition on vehicles that meet all of the following criteria: • 2020 Explorer/Aviator/Corsair • Built on or before 23-Jul-2020 • Inadvertently activates the reverse braking assist system while backing up Warranty Status: Eligible under provisions of New Vehicle Limited Warranty (NVLW)/Service Part Warranty (SPW)/Special Service Part (SSP)/Extended Service Plan (ESP) coverage. Limits/policies/prior approvals are not altered by a TSB. NVLW/SPW/SSP/ESP coverage limits are determined by the identified causal part and verified using the OASIS part coverage tool.
