d) Repeat steps b) and c) for DUT remote inputs that are accessible by the operator (e.g. switch inputs). A representative
switch may be used, but shall be approved by the FMC EMC department in writing prior to commencement of testing.
e)
Repeat step b), sequence 1 through 6 for DUT communications bus circuits accessible via diagnostic connectors.
Apply contact and air discharges directly to the connector pins as illustrated in Figure 21-2.
f)
Perform air discharge ± 25 KV (sequence 8) to DUT surfaces that are:
• Located in the passenger compartment, but are only in directly access from outside the vehicle (e.g. turn signal
stalk switch, window switches).
• Directly accessible from the outside of the vehicle (e.g. keyless entry keypad)
For each of the required discharge voltages, three (3) discharges of positive and three (3) discharges of negative
polarity shall be applied at each of the specified discharge points.
g)
After all discharges have been carried out (including handling tests), functional performance and parametric tests shall
be performed to verify that the DUT meets the requirements delineated in section 21.1.
