When Monitored:
With the ignition on.
Vehicle speed greater than 6 mph (9.6 km/h).
Set Condition:
Blind Spot Module (BSM) does not receive messages from the Left Rear Blind Spot Sensor.
Diagnostic Test
1. CHECK FOR ACTIVE DTC
1. Turn the ignition on.
2. With the scan tool, read BSM DTCs.
Does the scan tool display this DTC as active?
Yes
Go to Step 2.
No
The condition that caused this code to set is not present at this time. Check for an intermittent
condition by inspecting the related wiring harness for chafed, pierced, pinched, and partially
broken wires. Also inspect the related connectors for broken, bent, pushed out, spread,
corroded, or contaminated terminals.
Perform the BODY VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE,
Totally Integrated Power (TIPM) - Standard Procedure .
2. CHECK THE VOLTAGE OF THE (D764) AND (D765) BLIND SPOT SENSOR DATA LINK
