The Passlockā¢ Module will read an analog voltage from the Passlockā¢ Sensor. Based on an internal reference, the Passlockā¢ Module will determine if the measured voltage is open, shorted to ground, a valid code, or a tamper code. In this case, the Passlockā¢ Module is reading a tamper code.
ā¢ | The Passlockā¢ Module will inspect for a tamper code when the ignition is rotated from ON to crank. |
ā¢ | The Passlockā¢ Module is reading a tamper code form the Passlockā¢ Sensor for longer than 1.0 second. |
ā¢ | The vehicle will not run. The security telltale will be flashing. |
ā¢ | The Passlockā¢ state is Tamper. |
ā¢ | The DTC will clear after an ignition cycle has occurred without the fault. |
ā¢ | Passlockā¢ Module history codes will be cleared after 100 ignition cycles with no current codes active. |
ā¢ | Using a scan tool. |
ā¢ | Prior to replacing a Passlockā¢ Module, insure all the diagnostics have been completed, Refer to Diagnostic Trouble Code (DTC) List/Type for troubleshooting priority. |
ā¢ | Perform a visual inspection of the wiring and the connectors. |
ā¢ | Inspect the Passlockā¢ Sensor harness for an intermittent or poor connections (including the in-line connector). Refer to Testing for Intermittent Conditions and Poor Connections . |
The numbers below refer to the numbers on the diagnostic table.
This step test if DTC B3033 is intermittent.
This test inspects for a mechanical condition.
This step will determine if the condition is in the Passlockā¢ Module or the Passlockā¢ Sensor.
