Repair/Claim Coding Causal Part: RECALEM Condition Code: 04 Service Procedure 1. Reprogram the PCM using the latest software level of the appropriate Ford diagnostic scan tool. NOTE: Advise the customer that this vehicle is equipped with an adaptive transmission shift strategy which allows the vehicle's computer to learn the transmission's unique parameters and improve shift quality. When the adaptive strategy is reset, the computer will begin a relearning process. This relearning process may result in firmer than normal upshifts and downshifts for several days. 2. Does the vehicle exhibit a forced idle condition? (1). Yes - proceed to Step 3. (2). No - the repair is complete. 3. Remove the vehicle from forced idle. (1). Allow the vehicle to sit indoors to increase diesel exhaust fluid (DEF) tank temperature to greater than 0°C (32°F). (2). Start the vehicle and allow it to idle for 10-15 minutes. (3). Drive the vehicle forward at wide open throttle (WOT) for up to 2 minutes. It is very important to not back off the accelerator pedal when trying to get it out of forced idle. If the truck does not come out of forced idle mode after 2 minutes, stop the vehicle and idle for a few minutes before trying again. NOTE: Full power is immediately restored when the vehicle is cleared from forced idle. © 2020 Ford Motor Company All rights reserved.
