(b) Wiring harness remains disconnected
from parking brake oil pressure switch.
(c) Disconnect wiring harness
connector(s) from powertrain ECM
(WP 0063 00).
(d) Measure resistance between contacts

is between J2-53 (wire 419-YL) and the
circuit with lowest resistance, or short is
between J2-52 (wire G764-PK) and
circuit with lowest resistance. Replace
wiring harness in question (WP 0195 00
thru WP 0201 00).
3. Check switch operation.
(a) Wiring harness remains disconnected
from parking brake oil pressure switch.
(b) Connect one lead from multimeter to
contact A of harness connector on
switch.
(c) Connect other lead from multimeter to
contact B of harness connector on
switch.
(d) Measure resistance between contact A
and contact B. Note resistance.
(e) Disconnect multimeter lead from
contact B and connect lead to contact C.
(f) Measure resistance between contact A
1. If resistance from contact A to contact
and contact C.
C is less than 5 Ohms and resistance
from contact A to contact B is greater
than 5,000 Ohms, go to Test 4.
2. If resistance measurements do not
differ, replace parking brake oil
pressure switch (WP 0086 00).
