5.12.2
Checking door opening modules types 1 and 2
1. Start the customer service test programme.
2. Perform the steps of the customer service test programme up to the final step:
open door.
3. Measure the supply voltage at the (bus) connector of the cable connection.
4.
0
If the supply voltage agrees with the value given in the circuit diagram
►
replace the defective door opening model. (Page 140)
5.
0
If the supply voltage
does not
agree with the value given in the circuit
diagram
► check the line resistance R at the plug-in connections.
6.
0
If the line or plug-in connection is interrupted (R > 0 to infinity)
► replace the defective cable harness.
7.
0
If the line is intact (R = 0)
►
replace the defective power module (Page 91)
5.12.3
Checking door opening modules of type 3
1. Start the customer service test programme.
2. Perform the steps of the customer service test programme up to the final step:
