4. Check of switch (high pressure) operation.
0793 04 - Continued.
(a) Start engine. This will cause system
pressure to activate primary steering
pressure switch (TM 5-3805-291-10).
(b) Connect one lead from a multimeter to
contact A (wire C216-BK) of wiring
harness connector on the switch.
(c) Connect other lead from a multimeter
to contact B (wire 417-GY) of wiring
harness connector on the switch.
(d) Measure resistance between contact A
(wire C216-BK) and contact B (wire
417-GY). Note resistance.
(e) Disconnect multimeter lead from
contact B (wire 417-GY) and connect
lead to contact C (wire 484-YL).
(f) Measure resistance between contact A
1. If resistance from contact A to contact
(wire C216-BK) and contact C (wire
B is less than 5 Ohms and resistance
484-YL).
from contact A to contact C is greater
than 5,000 Ohms, go to Test 5.
2. If resistance from contact A to contact
B is not less than 5 Ohms or resistance
from contact A to contact C is not
greater than 5,000 Ohms, replace the
primary steering oil pressure switch
(WP 0088 00).
5. Check if diagnostic code remains active.
(a) Inspect and clean wiring harness
connector contacts.
(b) Reconnect all wiring harness
connectors.
(c) Operate machine (TM 5-3805-291-
10).
1. If CID 0793 FMI 04 is active, exit this
(d) Use messenger to determine if CID
procedure and repeat this procedure. If
0793 FMI 04 is present (TM 5-3805-
291-10).
cause of diagnostic code is not found,
replace powertrain ECM (WP 0063 00).
2. If CID 0793 FMI 04 is not active,
diagnostic code is not present at this
time. Resume normal machine
operation.
