4. Ignition ON, test for 4.8-5.2 V between the 5 V reference circuit terminal 1 and ground.

瀚慖f less than the specified range, test the 5 V reference circuit for a short to ground or an open/high resistance. If the circuit tests normal,

replace the K19 suspension control module.

瀚慖f greater than the specified range, test the 5 V reference circuit for a short to voltage. If the circuit tests normal, replace the K19

suspension control module.

5. Verify the scan tool Vertical Body Acceleration parameter is less than -3 m/s(2).

瀚慖f greater than the specified value, test the signal circuit for a short to ground. If the circuit tests normal, replace the K19 suspension

control module.

6. Install a fused jumper wire between the signal circuit terminal 2 and the low reference circuit terminal 3.

7. Verify the scan tool Vertical Body Acceleration parameter is greater than 3 m/s(2).

瀚慖f less than the specified value, test the signal circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace

the K19 suspension control module.

8. If all circuits test normal, replace the B162 vertical body acceleration sensor.
