Diagnostic Test
1.
VERIFY THAT DTC B120F-LEFT HEATED SEAT HI INDICATOR CONTROL CIRCUIT OPEN IS ACTIVE
With the scan tool, record and erase DTC’s
Operate the Heated Seat Switch in both positions several times.
With the scan tool, read DTC’s.
Does the DTC B120F-LEFT HEATED SEAT HI INDICATOR CON-
TROL CIRCUIT OPEN reset?
Yes
>> Go To 2
No
>> The conditions that caused this code to set are not present
at this time. Using the wiring diagram/schematic as a guide,
inspect the wiring and connectors.
Perform BODY VERIFICATION TEST – VER 1. (Refer to
BODY VERIFICATION TEST – VER 1).
2.
INSPECT PDC FUSES
Check PDC fuses #8 and #40.
Is either fuse open?
