  Is the connector intact?
  
  Yes
  - Move on to Step 3.
  No
  - Repair or replace the connector, then move on to Step 6.
CHECK FOR PRESENCE OF SHORT CIRCUIT TO GROUND ON THE VOLUMETRIC SENSOR
1. Check that the Volumetric Sensor and Body Computer Module connectors are connected.
2. Check continuity between PIN C of Volumetric Sensor (wiring side) and body.
  Is short-circuit present?
  
  Yes
  - Repair or replace the wiring because it is subject to a short circuit to ground, then proceed to 6.
  No
  - Move on to Step 4.
CHECK FOR PRESENCE OF OPEN CIRCUIT ON THE VOLUMETRIC SENSOR
1. Check that the Volumetric Sensor and Body Computer Module connectors are connected.
2. Check the continuity between PIN C of the Volumetric Sensor or the band joint and PIN X (connector C) of the Body Computer Module (wiring side).
  Is short-circuit present?
  
  Yes
  - Repair or replace the wiring because it is subject to an open circuit, then proceed to 5.
  No
  - Move on to Step 6.
CHECK THE VOLUMETRIC SENSOR OPERATION
1. Check the Volumetric Sensor operation.
  Is the Volumetric Sensor working?
  
  Yes
  - Move on to Step 6.
  No
  - Replace the Volumetric Sensor in accordance with the Service Information.
  - Move on to Step 6.
CHECK THAT THE BODY COMPUTER MODULE IS WORKING PROPERLY
1. Restore the electrical connections.
2. Connect the negative battery lead.
3. Connect the Scan Tool and carry out the Body Computer Module DTC deletion procedure.
4. Lock the door to enable the Anti-Theft Stand-By Mode.
5. Unlock the door to disable the Anti-Theft Stand-By Mode.
6. Wait at least 1.5 seconds.
7. Check whether the DTC is still present.
  Is the DTC still present?
  
  Yes
  - Repeat the checks from Step 1.
  - Replace the Body Computer Module if the DTC occurs again.
