MALFUNCTION
TEST OR INSPECTION
CORRECTIVE ACTION
3-11 Cylinder #3 Injector
9. Using digital multimeter
1. If continuity is found, replace
Fault - Continued
(WP 0296), test for continuity
engine ECM (WP 0101). Remove
between pins 38 and 45 on
jumper wire from pins 3 and 10 on
engine ECM connector N-C1
engine harness connector N-C2
(WP 0018, Figure 2).
(WP 0018, Figure 7) and connect
engine harness connector N-C2
(WP 0018, Figure 7) on valve
cover side connector NN-C1
(WP 0018, Figure 8).
2. If continuity is not found, replace
engine main wiring harness
(WP 0055). Ensure all harness
connectors are reconnected. Ver-
ify correct operation of machine
(TM 5-2410-241-10).
10. Remove jumper wire from pins 3
and 10 on engine harness con-
nector N-C2 (WP 0018, Figure 7)
and connect engine harness con-
nector N-C2 (WP 0018, Figure 7)
on valve cover side connector
NN-C1 (WP 0018, Figure 8).
11. Remove valve cover (WP 0106).
12. Install jumper wire between nuts
(Figure 4, Item 2).
13. Perform Injector Solenoid Test
1. If "OPEN" displayed, replace
injector wiring harness
(WP 0106). Ensure all harness
connectors are reconnected. Ver-
ify correct operation of machine
(TM 5-2410-241-10).
2. If "SHORT" displayed, replace
Fuel Injector (WP 0069). Ensure
all harness connectors are recon-
nected. Verify correct operation of
machine (TM 5-2410-241-10).
14. Disconnect engine harness con-
nector N-C2 (WP 0018, Figure 7)
from valve cover side connector
NN-C1 (WP 0018, Figure 8).
15. Perform Injector Solenoid Test
1. If "OPEN" displayed, proceed to
step18.
2. If "SHORT" displayed, proceed to
step 16.
16. Disconnect engine ECM connec-
tor N-C1 (WP 0018, Figure 2)
from engine ECM (WP 0101).
