2. If no active codes are present, the
problem does NOT exist at this
time. Resume normal operation.
2. Turn ignition switch and battery
disconnect switch to OFF position
(TM 5-2410-241-10).
3. Disconnect dash monitor connec-
tor E-C7 (WP 0018, Figure 5) from
instrument panel (WP 0262).
4. Remove left platform access panel
(WP 0207).
5. Disconnect steering control har-
ness connector X-C1 (WP 0018,
Figure 34) from platform harness
connector MA-C14 (WP 0018, Fig-
