Diagnostic Test
1.
CHECK FOR AN ACTIVE DTC
Turn the ignition on.
With the scan tool, record and erase DTCs.
Wait 30 seconds.
With the scan tool, read DTCs.
Does the scan tool display: U0208-LOST COMMUNICATION WITH HEATED SEATS CONTROL MODULE?
Yes
>> Go To 2
No
>> The condition that caused this code to set is not present at this time. Check for an intermittent condition
by inspecting the related wiring harness for chafed, pierced, pinched, and partially broken wires. Also
inspect the related connectors for broken, bent, pushed out, spread, corroded, or contaminated termi-
nals.
