After doing a little research on these DTCs, the technician
decided to call ALLDATA Tech-Assist. The Tech-Assist consultant
had seen this problem before and suggested inspecting the DSC
acceleration sensor for water damage or the sensor wiring harness
for being pulled to tightly, which could cause intermittent
connector separation. He told the tech that the DSC acceleration
sensor was located under the front passenger footwell carpet.
Confirmed Repair: The DSC Acceleration
Sensor was accessed and found to be saturated with water. Upon
further inspection, the tech found that the windshield cowl
drains were clogged and had been routing water into the footwell.
A new sensor was installed, the windshield cowl drains cleared,
and the carpet and footwell was dried out. The DTCs were cleared
and none returned after a test drive. Problem resolved.
