Repair/Claim Coding
Causal Part:

RECAL

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 SOBDMB and SOBDMC using the latest level software level of the FDRS scan tool.
3. Review freeze frame/snapshot data from when DTC P2797 initially triggered. Did the "EXTERIOR_TEMP" PID
read 32°F (0°C) or less when the DTC triggered?
(1). Yes - proceed to Step 4.
(2). No - refer to the WSM, Section 302-01 for additional diagnostics outside of this article. Repair is complete.
4. Clear DTCs. Road test the vehicle in conditions where the vehicle can remain above 10 mph (16 km/h) for at least
1 minute.
5. Retest DTCs. Are any DTCs present in the SOBDMB or SOBDMC?
(1). Yes - refer to the WSM, Section 302-01 for additional diagnostics outside of this article. Repair is complete.

(2). No - repair is complete.
