Rear Glass Break Sensor No Connection/Internal Fault

Diagram:

Fault Symptoms
The message "SERVICE ANTI-THEFT ALARM" is shown on SID.

Conditions
No connection with rear glass breakage sensor.

Main Condition
The diagnostic trouble code is generated if a fault is found during two test cycles in succession. A test cycle lasts one second, i.e. it takes two seconds from when the fault occurs until a diagnostic trouble code is generated. If the fault disappears, the trouble code is deleted from the control module memory after the ignition has been turned ON 20 times.

Diagnostic trouble codes are not generated if the voltage is below 11 V or over 14 V.
