2. Remove small cover under instrument panel at the right.

CONNECTING ADAPTER TO VOLT/OHM MEASURING INSTRUMENT:

Electronic Control Unit (9) For Temperature Control, Electronic Switching Unit (19) For Blower Control:

Adapter # 126 589 03 21 00:

1. Pull 12-pole coupler from electronic switching unit (9) for temperature control and connect to adapter.
2. Connect adapter with volt/ohm measuring instrument to 12-pole coupler and switch adapter to test step 1.
