Causes

Damaged or disconnected switch assembly connector
Broken, shorted, or corroded wiring in the switch circuit
Faulty driver-side rear seat switch assembly
Faulty body control module / seat control module
Blown fuse or poor battery supply to the circuit
Software/firmware issue or module configuration problem

Symptoms

Seat switch not operating or intermittent operation (fold, recline, heater, etc., depending on function)
Malfunction indicator or warning message related to seat functions
Certain seat functions disabled or respond incorrectly
Related DTCs present for seat circuits or communication bus

What to check

Retrieve all related DTCs with a diagnostic scan tool and record freeze frame/occurance
Visually inspect the driver-side rear seat switch assembly and surrounding area for damage or moisture
Check connector for corrosion, bent pins, or loose terminals; reseat connector
Visually inspect wiring harness routing for chafing, breaks or pinched sections
Check relevant fuses and battery supply to the seat circuit
Use scan tool to command the switch functions and observe module responses and any live data values

Signal parameters

Battery supply to circuit: ~12 V (with ignition on)
Reference/sensor voltage (if used): approx. 5 V (varies by design)
Switch closed continuity: near 0 Ω; open: very high/OL
CAN/LIN communication: message presence on bus when module involved (if applicable)
Signal change expected when switch actuated (instantaneous transition or proportional depending on switch type)

Diagnostic algorithm

Connect a diagnostic scanner and read all DTCs and freeze-frame data; note related body/seat/module codes.
Attempt to operate the affected seat functions using the switch and the scanner’s bi-directional controls; observe live data and any module responses or errors.
Visually inspect the switch assembly, connector and harness for damage, corrosion or water intrusion. Repair any physical damage found.
With ignition off, disconnect the switch connector and inspect pins for corrosion/looseness. Reconnect firmly. Clear codes and retest.
With ignition on, confirm battery voltage at the switch power pin; check ground for continuity to chassis. Repair poor power/ground connections.
Check continuity/resistance of the switch circuit while actuating the switch (bench test switch if removed). Replace if switch fails continuity/response criteria.
If the circuit and switch test good, check communication lines (CAN/LIN) and module inputs for activity. Repair bus faults and reprogram or replace module if necessary.
If intermittent, perform wiggle tests along harness while monitoring live data for change and inspect for chafed or broken wires hidden in seats or trim.
After repairs, clear DTCs, retest all seat functions and verify that B1332 does not reappear and that related codes are resolved.

Likely causes

Connector loose/corroded at rear seat switch
Open or short in the seat switch wiring harness
Failed seat switch assembly

Fault status

⚠️ Status

The driver-side rear seat switch assembly circuit is reporting an abnormal condition (open, short, incorrect signal, or communication failure) to the control module. This may disable or impair seat functions.

🟡 Repair difficulty: Medium

⏱️ Diagnostic time: 0.5-1.5 hours
