BCM DTC Fault Trigger Conditions
Description | Fault Trigger Conditions | |||
|---|---|---|---|---|
DTC | ||||
B109F:01 | Intrusion Sensor Module: General Electrical Failure | Sets when the BCM detects a short to ground from the intrusion sensor LIN circuit. | ||
B109F:02 | Intrusion Sensor Module: General Signal Failure | Sets when the BCM detects a communication fault with the intrusion sensor. | ||
B109F:08 | Intrusion Sensor Module: Bus Signal / Message Failure | Sets when the BCM detects a communication fault with the intrusion sensor. | ||
B109F:97 | Intrusion Sensor Module: Component or System Operation Obstructed or Blocked | Sets when the intrusion sensor communicates to the BCM that it detects the motion sensor is blocked. | ||
B109F:9A Intrusion Sensor Module: Component or System Operating Conditions | Sets when the BCM detects a communication fault with the intrusion sensor. | |||
Possible Causes
Fuse Wiring, terminals or connectors Intrusion sensor BCM
Visual Inspection and Diagnostic Pre-checks
Inspect the BCM fuse 18 (5A)
PINPOINT TEST B : THE ALARM SYSTEM DOES NOT ACTIVATE FROM THE INTRUSION SENSOR
NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
