Is the theft code b2960 incorrect or valid?
Well we know many things will do this like the fuel pump, ignition components, starter, etc. So you then go and scan the vehicle and you get the code B2960 (key code incorrect but valid). I also get a U1000 code a lot with this code which may be related, may not be.
When does the BCM set the fail enable code?
The BCM will set this code if it sees signal input voltage (yellow wire) higher than 4.9-volts for 1-sec after turning the ignition switch to CRANK. The BCM will enter fail enable mode and will allow the engine to start and run.
Can you read the fault code on a Mercedes Benz?
Can read fault codes from multiple systems such as transmission, engine, ETS, airbag and more. Can clear fault codes. Can read and erase all fault codes on Mercedes-Benz cars. Only works on MB but can perform further troubleshooting including SBC brake systems, convertible systems, Air Conditioner (A/C) system. 3. Mercedes-Benz Star Diagnostic DAS

What happens if the PassLock security light is not read?
If the incorrect code is read, the system will not allow the engine to start for four minutes—even if the correct code is received. The security light will remain on or a message will be displayed on the Driver Information Center (depending on the model) when this occurs. Both of these starter interrupt systems are very effective on their own.
When does the BCM light the security light?
The BCM will light the SECURITY light steady. Once the BCM detects a valid voltage value from the sensor, the B3031 changes to history code. The BCM sets this code when it sees a voltage signal from the sensor (yellow wire) indicating a tamper situation during engine startup.
What happens if the security light comes on while driving?
If the customer says the security light came on while driving and the no start happened later, then my diagnoses will go a different direction. If the customer says the light was flashing after the no start or they say they didn’t notice the light, I will continue to proceed in this direction.
What does system fault code b2960 mean on a Chevy?
When the sensor defect starts, it usually presents itself as system fault code B2960. A red (or yellow) “security” warning light will stay illuminated and the engine will either a) never start or b) start for a moment and then shut down. How to Fix Passlock for Chevy Vehicles

When to send a Class 2 message to the PCM?
If the voltage measured is within a valid range, the BCM will send a class 2 message to the PCM to enable vehicle starting. If the voltage measures is not within a valid range, a class 2 message is sent to the PCM to disable vehicle starting.
