What does it mean?
B1354 is a Body (airbags, seat belts, body electronics) fault code. It indicates: PAB Circuit Short To Ground .
Symptoms
- SRS lamp on and the passenger airbag deactivated
- If the short is intermittent the lamp often comes on over rough roads or when the dash is knocked
- Other passenger side restraint codes may be stored alongside it
- The code sets again within seconds of clearing when the short is permanent
- No change in engine operation
Likely causes
- Squib wire rubbed through against a dash brace, bracket edge or trim screw and touching bare metal
- Water or coolant in the passenger footwell connector giving a leakage path to ground
- Loom crushed where it passes the A-pillar or behind the glove box after trim work
- Terminal backed out of the airbag connector and touching the metal mounting bracket
- Internal short to the case inside the passenger inflator module
- Dash accessory or audio installation screwed or cable-tied through the SRS loom
- Airbag control module internal fault
How to fix it
- Read all stored restraint codes first; several codes together point at the loom rather than at the airbag
- Power the system down safely: ignition off, battery disconnected, reserve power discharge time observed
- Unplug both the airbag connector and the control module connector, then check each squib wire for continuity to body ground; a low reading confirms a shorted harness
- If the harness is clean with both ends unplugged, the short is inside the inflator or the control module
- Inspect the loom route for chafe against metal edges, and look for a screw or clip driven through it
- Dry out and reseal any footwell water leak before repairing the wiring
- Repair with the correct restraint-system repair parts rather than a twisted splice, then clear and verify the lamp goes out
