B1A3A
B1A3A-SECURITY RECEIVER SENSOR CIRCUIT LOW
For a complete wiring diagram refer to Diagrams/Electrical.
- When Monitored:
When the VTSS is armed.
- Set Condition:
If the current flow on the sensor signal circuit is above a specified range this DTC will set.
Diagnostic Test
1. TEST FOR INTERMITTENT CONDITION
Turn the ignition on.
With the scan tool, record and erase DTC's.
Turn the ignition off and remove the key from the ignition.
Close all doors and arm the VTSS and wait two minutes.
Disarm the VTSS turn the ignition on.
Turn the ignition on and with the scan tool, read DTC's.
Does the scan tool display B1A3A-SECURITY RECEIVER SENSOR CIRCUIT LOW ?
Yes
- Go To 2
No
- The conditions that caused this code to set are not present at this time. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
2. INTRUSION SENSOR RECEIVER
Turn the ignition off.
Disconnect the Intrusion Sensor Receiver connector.
Turn the ignition on and with the scan tool, erase DTC's.
Turn the ignition off and remove the key from the ignition.
Close all doors and arm the VTSS and wait two minutes.
Disarm the VTSS turn the ignition on.
With the scan tool, read DTC's.
Does the scan tool display B1A44-SECURITY RECEIVER SENSOR CIRCUIT OPEN?
Yes
- Replace the Intrusion Sensor Receiver.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
No
- Go To 3
3. CHECK THE (G460) INTRUSION RECEIVER SENSOR SIGNAL CIRCUIT SHORT TO GROUND
Turn the ignition off.
Disconnect the Intrusion Transceiver Module connector.
Measure the resistance between ground and the (G460) Intrusion Receiver Sensor Signal circuit at the Intrusion Transceiver Module connector.
Is the resistance below 5.0 ohms?
Yes
- Repair the (G460) Intrusion Receiver Sensor Signal circuit for a short to ground.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
No
- Replace the Intrusion Transceiver Module.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
