My aunts aztek just threw a B2961 code. I looked it up and it is B2961 - Key In Ignition Circuit Malfunction. I have searched and searched but cannot not find out what exactly this code means. Does anybody have an idea? TIA

 

DTC B2961
Circuit Description
The body control module (BCM) uses a key in ignition input in order to control certain features in the vehicle. These features are in the following systems:

Content Theft Deterrent, if equipped
Audible Warnings
Automatic Door Locks
The ignition switch switches the key in ignition input circuit to ground when you fully insert the ignition key into the ignition switch. This in turn pulls the BCM key in ignition input low.

Conditions for Running the DTC
The ignition is on.

Conditions for Setting the DTC
The ignition 0 input is active, high signal and the key in ignition input is inactive, high signal.
The conditions above must be present for more than 0.3 seconds.
Action Taken When the DTC Sets
The BCM stores DTC B2961 in memory.

Conditions for Clearing the DTC
The DTC becomes history when the fault is no longer present.
A history DTC will clear after 100 consecutive ignition cycles if the condition for the malfunction is no longer present.
The BCM receives the clear code command from the scan tool.
