Circuit Description
This circuit supplies the Passlock™ data to the body control module (BCM) from the Passlock™ sensor, CKT 1836.
Conditions for Setting the DTC
All of the following conditions must be met:
| • | Ignition 0 is active. |
| • | The Passlock™ code does not equal the learned key code during the engine start for 3 consecutive key cycles or for 1 second at any time while driving. |
Action Taken When the DTC Sets
| • | The BCM stores DTC B2960 in the BCM memory. |
| • | DTC B2960 will be set under the following conditions: |
| - | On an attempted start, the car will not start and the security light flashes for 10 minutes |
| - | While driving: |
| • | The SECURITY indicator illuminates |
| • | The vehicle will start on the next key ON |
Conditions for Clearing the DTC
| • | The BCM goes to sleep and reinitializes with the fault cleared. |
| • | All of the BCM history codes will be cleared after 100 ignition cycles (from OFF to ON) with no current codes active during the 100 ignition cycles. |
| • | Use a scan tool. |
Diagnostic Aids
If the DTC is a history DTC, the problem may be intermittent. Perform the tests shown while wiggling the wiring and connectors. This will cause the malfunction to appear.
