DIAGNOSIS/TROUBLESHOOTING (FAULT CODE 11)

Work instruction			Display OK	If not OK
1	Visual inspection	Check plug B on alarm system control module for contact and corrosion	Step 2	Repair plug B or wiring harness -> End
2	Check power supply (terminal 30)	Switch off ignition Unplug plug B from the "alarm system" control module. Measure voltage between plug B on control module pin 7 and ground	> 11 V Step 7	Step 3
3	Check wire from the "mini relay" to the alarm system control module for open circuit	Pull off mini relay in the fuse box Measure resistance between plug B on control module pin 7 and pin 1 on the mini-relay carrier	< 5 Step 4	Repair wiring harness -> End
4	Check wire from the current distributor (F5) to the mini-relay carrier	Measure voltage between the mini-relay carrier pin 4 and ground	> 11 V Step 5	Repair wiring harness or check fuse in current distributor -> End
5	Check wire from ground point 3 to the mini-relay carrier	Measure resistance between the mini-relay carrier pin 5 and ground	< 5 Step 6	Repair wiring harness or check ground point 3 for corrosion -> End
6	Replace mini relay		-> End
7	Replace control module		-> End
