Condition
Some customers may comment on a SES MIL and a Service Theft Deterrent
System message displayed in the DIC. When checking for DTC’s, any of the following
DTC’s may be set: B113C, B13AC, B1AC3, B195D, B195E, U3018 and/or U3501. Also,
fuse F49DR in the right IP fuse block will be open.
Cause
The 12 volt power accessory port X80H has a LED illuminated ring around its
perimeter (1), shown below. The LED illuminated ring is part of the 12 volt accessory
port receptacle retainer, see 2nd photo. The 12 volt accessory port receptacle
retainer has two contact tabs for the LED illuminated ring (2 and 3) which mate to
the 12 volt accessory port receptacle (5 and 6), see 3rd photo. Tab 2 is for the power
to the LED illuminated ring circuit 6817 and tab 3 is the ground which should only
contact the outer metal body (6) of the 12 volt accessory port receptacle. If tab 3 is
improperly formed or gets bent, it can short out between the metal body (6) and the
slide contact (5) for tab 2, as shown below in call out 4. Tab 3 should only contact
the metal body of the 12 volt accessory port receptacle (6).

Correction:
Following SI, remove the 12 volt power accessory port X80H and inspect grounding tab 3. If the tab is shorting out
between the metal body (6) and slide contact (5) for tab 2 then replace the 12 volt Accessory Power
Port Receptacle Retainer.
