Circuit/System Testing

WARNING: This page is about a different car, the 2007 Suzuki XL7. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: When removing connectors, inspect for damage or corrosion. Damage or corrosion in the following requires repair or replacement of the affected component/connector:

The PPS module
The SDM module
The PPS module harness connector
The SDM wiring harness connector

Ignition ON, Verify the passenger air bag ON/OFF indicators illuminate.
- If the indicators do not illuminate, refer to PASSENGER PRESENCE SYSTEM INDICATOR CIRCUIT MALFUNCTION .
Ignition ON, verify no PPS DTCs are set.
- If any PPS DTCs are set as current or history, refer to DIAGNOSTIC TROUBLE CODE (DTC) LIST - VEHICLE DIAGNOSTIC INFORMATION .
Verify the correct PPS part number is installed in the vehicle.
- If the wrong PPS was installed, replace with the correct PPS.
Ignition OFF, disconnect the harness connector at the PPS module.
Remove the SDM connector. Refer to INFLATABLE RESTRAINT SENSING AND DIAGNOSTIC MODULE REPLACEMENT .
Test the occupant sensor serial data circuit for an open/high resistance between the PPS module and SDM connector.
- If an open/high resistance exists, make the appropriate repair.
Ignition OFF, test for less then 1 ohm of resistance between the PPS module circuit terminal D and ground.
- If not the specified value, test the circuit for an open/high resistance.
Ignition ON, verify a test lamp illuminates between the PPS module circuit terminal A and ground.
- If the test lamp does not illuminate, test the circuit for a short to ground or an open/high resistance. If circuit tests normal replace the PPS module.
If all circuits test normal, and DTC B0081 is set as current, replace the SDM.
