Circuit/System Verification
Ignition ON, observe the scan tool Vertical Body Acceleration parameters. The parameters should be 0 m/s(2).
Circuit/System Testing
1. Ignition ON, verify that DTC C0870 is not present.
瀚慖f the DTC is present, refer to DTC C0870 (See: C Code Charts/C0870) to diagnose that DTC prior to this diagnostic.
2. Ignition OFF, disconnect the harness connector at the appropriate B162 vertical body acceleration sensor.
3. Ignition OFF, open/close doors, and wait 60 seconds. Test for less than 5 ohm between the low reference circuit terminal 3 and ground.
瀚慖f greater than the specified value, test the low reference circuit for short to voltage or an open/high resistance. If the circuit tests normal,
replace the K19 suspension control module.
