1. If active code 262-4 code is pres-
ply Short to Ground -
Event Codes (WP 0013).
ent, proceed to step 18.

2. If 262-4 code is not active,
replace turbo inlet pressure sen-
sor (WP 0066). Ensure all har-
ness connectors are reconnected.
Verify correct operation of
machine (TM 5-2410-241-10).
18. Turn ignition switch and battery
disconnect switch to OFF position
(TM 5-2410-241-10).
19. Disconnect engine ECM connec-
tor N-C1 (WP 0018, Figure 2)
from ECM.
20. Using digital multimeter
1. If continuity is found, replace ECM
(WP 0296), test for continuity
harness (WP 0105). Ensure all
between pin 2 on engine ECM
harness connectors are recon-
connector N-C1 (WP 0018,
nected. Verify correct operation of
Figure 2) and all other pins on
machine (TM 5-2410-241-10).

2. If continuity is not found, proceed
(WP 0018, Figure 2).
to step 21.
21. Using digital multimeter
1. If continuity is found, replace ECM
(WP 0296), test for continuity
harness (WP 0105). Ensure all
between pin 3 on engine ECM
harness connectors are recon-
connector N-C1 (WP 0018,
nected. Verify correct operation of
Figure 2) and all other pins on
machine (TM 5-2410-241-10).

2. If continuity is not found, proceed
(WP 0018, Figure 2).
to step 22.
22. Disconnect engine ECM connec-
tor V-C4 (WP 0018, Figure 1)
from ECM.
23. Using digital multimeter
1. If continuity is found, replace ECM
(WP 0296), test for continuity
harness (WP 0105). Ensure all
between pin 2 on engine ECM
harness connectors are recon-
connector V-C4 (WP 0018,
nected. Verify correct operation of
Figure 1) and all other pins on
machine (TM 5-2410-241-10).
