Diagnostic Trouble Code Charts (Part 2 Of 2):

Wiring Schematic:

CIRCUIT DESCRIPTION
The Passlock module will read an analog voltage from the Passlock sensor. Based on an internal reference, the Passlock module will determine if the measured voltage is open, shorted to ground, a valid code, or a tamper code. In this case, the Passlock module is reading a tamper code.

CONDITIONS FOR SETTING THE DTC
^ The Passlock module will inspect for a tamper code when the ignition is rotated from ON to crank.
^ The Passlock module is reading a tamper code form the Passlock sensor for longer than 1.0 second.

ACTION TAKEN WHEN THE DTC SETS
^ The vehicle will not run. The security telltale will be flashing.
^ The Passlock state is Tamper.

CONDITIONS FOR CLEARING THE DTC
^ The DTC will clear after an ignition cycle has occurred without the fault.
^ Passlock module history codes will be cleared after 100 ignition cycles with no current codes active.
^ Using a scan tool.

DIAGNOSTIC AIDS
^ Prior to replacing a Passlock module, ensure all the diagnostics have been completed, Refer to Diagnostic Trouble Code (DTC) Displaying (Domestic) for troubleshooting priority. Domestic
^ Perform a visual inspection of the wiring and the connectors.
^ Inspect the Passlock sensor harness for an intermittent or poor connections (including the in-line connector). Refer to Intermittents and Poor Connections. Intermittents and Poor Connections

TEST DESCRIPTION
The numbers below refer to the numbers on the diagnostic table.
2. This step test if DTC B3033 is intermittent.
3. This test inspects for a mechanical condition.
5. This step will determine if the condition is in the Passlock module or the Passlock sensor.
