Ignore all codes other then 262-3, which will be generated due to
harness disconnection.
5. Check for Diagnostic Codes or
1. If active code 262-3 code is pres-
Event Codes (WP 0013).
ent, proceed to step 6.
2. If 262-3 code is not active,
replace oil pressure sensor
(WP 0091). Ensure all harness
connectors are reconnected. Ver-
ify correct operation of machine
(TM 5-2410-241-10).
6. Turn ignition switch and battery
disconnect switch to OFF position
(TM 5-2410-241-10).
7. Disconnect atmospheric pressure
sensor connector N-C4
(WP 0018, Figure 35) from atmo-
spheric pressure sensor
(WP 0090).
8. Turn battery disconnect switch
and ignition switch to ON position
(TM 5-2410-241-10).
9. Check for Diagnostic Codes or
1. If active code 262-3 code is pres-
Event Codes (WP 0013).
ent, proceed to step 10.
2. If 262-3 code is not active,
replace atmospheric pressure
sensor (WP 0090). Ensure all har-
ness connectors are reconnected.
Verify correct operation of
machine (TM 5-2410-241-10).
10. Turn ignition switch and battery
disconnect switch to OFF position
(TM 5-2410-241-10).
11. Disconnect air inlet manifold pres-
sure sensor connector/turbo-
charger outlet pressure sensor
connector N-C5 (WP 0018,
Figure 36) from inlet manifold
pressure sensor (WP 0092).
12. Turn battery disconnect switch
and ignition switch to ON position
(TM 5-2410-241-10).
