The control module is receiving invalid or out-of-range data from Seat Control Module E on the vehicle network. This typically affects powered seat position, memory, or adjustment functions.
Common Causes
40%
Seat control module internal failure causing erratic signal output
30%
Damaged wiring or corroded connectors at seat control module
15%

10%
Poor power or ground connection at seat control module
5%
Communication network issue affecting multiple modules on same bus segment
Diagnostic Steps
1
Step 1: Check seat control module power and ground circuits with multimeter (verify battery voltage and clean ground)
2
Step 2: Inspect connectors under seat for damage, water intrusion, or corrosion from floor moisture
3
Step 3: Monitor seat position sensor data in real-time while operating seat adjustments to identify erratic values
4
Step 4: Test resistance of CAN High and CAN Low circuits at seat module connector (should be approximately 60 ohms between them)
5
Step 5: Substitute known-good seat control module if all circuits test properly to confirm module failure
Estimated Repair Cost
$200 - $900
