Repair/Claim Coding
Causal Part:

RECALEM

Condition Code: 04

Service Procedure
1. Connect a battery charger such as Rotunda GRX-3590 or DCA-8000 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 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 level software level of the FDRS scan tool.
NOTE: Advise the customer 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.
3. Refer to the WSM, Section 303-13C Evaporative Emissions - 3.5L V6 PowerBoost (CN) > Diagnosis and Testing >
Pinpoint Test HX: Evaporative Emission (EVAP) System And Monitor and follow normal diagnostics outside of this
article. Repair is complete.
