Test E: The Occupant Classification Sensor Does Not Respond To The Diagnostic Tool

PINPOINT TEST E: THE OCCUPANT CLASSIFICATION SENSOR DOES NOT RESPOND TO THE DIAGNOSTIC TOOL

E1-E2:

E3:

Normal Operation
The occupant classification sensor communicates with the diagnostic tool through the high speed controller area network (CAN), circuits VDB04 (WH/BU) and VDB05 (WH).

Check the high speed CAN circuits VDB04 (WH/BU) and VDB05 (WH) between the occupant classification sensor C3159 and the data link connector (DLC) C251. The total resistance values must not be more than 5 ohms. If the resistance is more than 5 ohms there is an open in one of the high speed CAN circuits, damage to the DLC C251, damage to the occupant classification sensor C3159, or a problem in an in-line connector.

Possible Causes
- high speed CAN data plus circuit VDB04 (WH/BU) open
- high speed CAN data minus circuit VDB05 (WH) open
- occupant classification sensor C3159
- occupant classification sensor
