Notes:
The following test steps are only performed for A/C control heads -E87- with two displays:
Teststep 2.2 (the instrument panel interior temperature sensor -G56- is installed in A/C control heads -E87- with one
display)
Test step 5.7 (the interior temperature sensor fan -V42- is installed in A/C control heads -E87- with one display)
