Symptoms
- The affected function (lighting, locking, windows, seats, climate or restraint) does not work or works intermittently
- Warning light or message on the instrument cluster
- Possible battery drain if a module stays awake
Common causes
- Damaged, chafed or corroded wiring in the Seat Driver Rear Down circuit
- Corroded, loose or water-damaged connector terminals
- Failed Seat Driver Rear Down component (sensor, solenoid or actuator)
- Poor ground connection for the module or component
- Faulty control module driver (rare, confirm all else first)
How to diagnose
- Read freeze frame data and note when the code set (cold start, under load, after rain)
- Inspect the Seat Driver Rear Down connector for bent pins, corrosion and water; wiggle the harness with the engine running and watch live data
- Measure supply voltage and ground at the connector with the key on
- Check the signal wire for shorts to ground or battery and for continuity to the control module
- Test or substitute the Seat Driver Rear Down only after wiring and connectors are confirmed good
- Clear the code and complete a drive cycle to confirm the repair
Frequently asked questions
Can I keep driving with B1759?
Yes. The fault does not affect safety or driveability, but it will keep the warning light on and may fail an inspection.
Will clearing B1759 fix it?
No. Clearing only erases the stored code; it returns as soon as the monitor runs again unless the cause is repaired.
