Circuit/System Verification

B1019 3A

1. With a scan tool, verify DTC B1370 is not set as current in the SDM.

瀚慖f DTC is current refer to DTC B1370 (See: B Code Charts/B1370).

2. If equipped with PPS, verify the appropriate PPS indicator segments illuminate by occupying and un-occupying the passenger seat.

瀚慖f the PPS indicator segments do not illuminate properly, replace the PPS indicator.

Circuit/System Testing

Important: When removing connectors inspect for damage or corrosion. Damage or corrosion in the following requires repair or

replacement of the affected.

* The PPS module

* SDM

* The PPS module wiring harness connector

* SDM wiring harness connector

B1019 00

1. Ignition ON, verify the scan tool End Model Part Number is correct for the vehicle.

瀚慖f the part number is incorrect, reprogram the SDM.

Important:

* If not equipped with PPS, the scan tool parameter should display Not Present and the PPS indicator should not be present on the

vehicle

* If equipped with PPS, the scan tool parameter should display Auto, Manual, or Auto + Man and the PPS indicator should be

present on the vehicle

2. Observe the scan tool PPS Options parameter to determine how the vehicle PPS is currently configured in the SDM. Verify the actual vehicle

equipment and the current configuration indicated by the scan tool parameter are the same.

瀚慖f the original configuration does not match the actual vehicle equipment, reprogram the SDM with the correct configuration.

3. Ignition OFF, disconnect the harness connectors at the SDM and verify the connector is in good condition and has no bent pins, terminals or

shorting bars

瀚慖f damage is found, repair the bent pins, terminals or shorting bars as needed and perform the Setup New SDM procedure.

4. Connect the harness connector at the SDM.

5. Ignition ON, verify the scan tool System Configuration matches the actual components installed on the vehicle.
