Raider V6-3.7L SOHC (2006)
Seat Occupant Sensor: Testing and Inspection
DIAGNOSIS AND CHECKOUT PROCEDURE FOR SEAT WEIGHT SENSORS
1. VERIFY COMPLAINT
1. Turn the ignition off.
2. Move the front passenger seat to the full rear position. Verify that the seat is empty, the seat back is in the normal upright position, and that the
seat is not interfering with any interior components.
3. Verify that all related connectors are properly seated and locked.
4. Turn the ignition on.
5. With the scan tool in OCM, select Data Display and note the Passenger Seat Weight Sensor voltage for all four sensors (Left Front, Right
Front, Left Rear and Right Rear).
6. Move the front passenger seat to the mid track position.
7. Using the scan tool, note the Passenger Seat Weight Sensor voltage for all four sensors.
8. Move the front passenger seat to the full forward position.
9. Using the scan tool, note the Passenger Seat Weight Sensor voltage for all four sensors. The voltage should be from 1.4 to 3.6 volts for each
sensor in each position (full rear, mid track, and full forward).
Q: Is any sensor's voltage reading out of the acceptable range in any position?
YES: Go To 2
NO: Perform test B1BA7 Occupant Classification System Verification Required. See: Powertrain Management/Computers and Control
Systems/Testing and Inspection/Diagnostic Trouble Code Tests and Associated Procedures/B Code Charts/B1BA7
If the test passes, the seat weight sensing system is working properly. Return to the procedure that directed you to this procedure.
2. CHECKING FOR BENT FLOOR PAN
1. Turn the ignition off.
2. Loosen all of the mounting screws retaining the front passenger seat to the vehicle crossmembers, but do not remove them. Verify that the seat
is loose and that no binding exists between the seat and the crossmembers.
3. Move the front passenger seat to the full rear position and then to the full forward position.
4. Tighten all of the mounting screws to specification.
5. Move the front passenger seat to the full rear position.
6. Turn the ignition on.
7. Using the scan tool, note the Passenger Seat Weight Sensor voltage for all four sensors.
8. Move the front passenger seat to the mid track position.
9. Using the scan tool, note the Passenger Seat Weight Sensor voltage for all four sensors.
10. Move the front passenger seat to the full forward position.
11. Using the scan tool, note the Passenger Seat Weight Sensor voltage for all four sensors. The voltage should be from 1.4 to 3.6 volts for each
sensor in each position.
Q: Is any sensor's voltage reading out of the acceptable range in any position?
YES: Go To 3
NO: Perform test B1BA7 Occupant Classification System Verification Required. See: Powertrain Management/Computers and Control
Systems/Testing and Inspection/Diagnostic Trouble Code Tests and Associated Procedures/B Code Charts/B1BA7
If the test passes, the seat weight sensing system is working properly. Return to the procedure that directed you to this procedure.
3. CHECKING SEAT TO RISER STRESS
1. Turn the ignition off.
2. Loosen all of the mounting screws retaining the front passenger seat track to the riser, but do not remove them. Verify that the seat track is
loose and that no binding exists between the seat track and the risers.
3. Turn the ignition on.
4. Using the scan tool, note the Passenger Seat Weight Sensor voltage for all four sensors. The voltage should be from 1.5 to 3.5 volts for each
sensor.
Q: Is any sensor's voltage reading out of the acceptable range?
YES: Go To 4
NO: Visually inspect for damaged or bent risers and crossmembers. Also, verify that the riser holes line up with the seat mounts in the
crossmembers. If riser damage is apparent, replace the risers. Then, reinstall the Seat Weight Sensors, and Go To 6.
NOTE: Failure to follow test instructions or aborting the test will cause faults to set when performing the Occupant Classification Module System
Verification Test. To prevent faults due to process errors: Verify That All Tests Steps That Led You Here Were Performed As Directed; Verify
