Pinpoint Test S: THE MODULE DOES NOT RESPOND TO THE JAGUAR APPROVED DIAGNOSTIC TESTER - INTRUSION SENSOR

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2008 Jaguar S-Type, 2007 Jaguar S-Type, 2006 Jaguar S-Type, 2005 Jaguar S-Type, and 2004 Jaguar S-Type. However, it is still accessible from the selected car via links, so may be relevant.

CHECK INTRUSION SENSOR MODULE FOR DAMAGE
INSPECT the intrusion sensor module for damage.

Does the intrusion sensor module indicate signs of damage?

YES: INSTALL a new intrusion sensor module. CLEAR the DTC. TEST the system for normal operation.

NO: Go to step 2.
CHECK K-LINE FOR SHORT CIRCUIT TO GROUND
Turn the ignition switch to the OFF position.

Disconnect the battery negative terminal.

Measure the resistance between diagnostic connector FC001, pin 7 (K-line) and GROUND.

Is the resistance less than 5 ohms?

YES: REPAIR the circuit. For additional information, refer to appropriate SYSTEM WIRING DIAGRAMS article. CLEAR the DTC. TEST the system for normal operation.

NO: Go to step 3.
CHECK K-LINE FOR SHORT CIRCUIT TO BATTERY
Turn the ignition switch to the OFF position.

Disconnect the battery negative terminal.

Measure the resistance between diagnostic connector FC001, pin 7 (K-line) and pin 016, BATTERY.

Is the resistance less than 5 ohms?

YES: REPAIR the circuit. For additional information, refer to appropriate SYSTEM WIRING DIAGRAMS article. CLEAR the DTC. TEST the system for normal operation.

NO: Go to step 4.
CHECK FOR OPEN CIRCUIT ON K-LINE BETWEEN DIAGNOSTIC CONNECTOR AND THE INTRUSION SENSOR MODULE
Turn the ignition switch to the OFF position.

Disconnect the battery negative terminal.

Disconnect the intrusion sensor module electrical connector, CA250.

Measure the resistance between diagnostic connector FC001, pin 7 (K-line) and CA250, pin 008

Is the resistance less than 5 ohms?

YES: INSTALL a new intrusion sensor module. CLEAR the DTC. TEST the system for normal operation.

NO: REPAIR the circuit. For additional information, refer to appropriate SYSTEM WIRING DIAGRAMS article. CLEAR the DTC. TEST the system for normal operation.
