CORRECTIVE ACTION
3.
APPROPRIATE GENERATOR ON-LINE INDICATOR DOES NOT LIGHT AT ICC/CRG CONTROL
PANEL (cont).
b.
If continuity does not exist between TB1-17 and P8 pin G, replace P8 wiring harness
(paragraph 4-24.d).
c.
If continuity does not exist between P11 pin H and TB1-18, disconnect P10 from PDU
connector J10 and check continuity from P11 pin H to P10 pin H. If continuity does not
exist, replace P10, P11 auxiliary cable. If continuity does exist, replace J10 wiring
harness (paragraph 4-24 c).
d.
If continuity does not exist between TB1-18 and P9 pin G, replace P9 wiring harness
(paragraph 4-24 e).
4.
ICC/CRG LOW FUEL LIGHT GIVES FALSE LOW FUEL WARNING.
Step 1.
Disconnect P4, P7 fuel cable from adapter plate assembly and fuel tank. Using multimeter,
check continuity between J4 pin A and J7 pin C.
a.
If continuity exists, cable is shorted Replace cable.
b.
If continuity does not exist, go to step 2.
Step 2.
Using multimeter, check continuity between J4 pin A and TB2-5.
a
If continuity exists, J4 wiring harness is shorted. Notify higher level of maintenance for
wiring harness replacement or repair.
b.
If continuity does not exist, go to step 3.
Step 3.
Disconnect control cable from ICC/CRG and PDU connector J6. Using multimeter, check
continuity between pin F on one connector and pin L on opposite connector.
a.
If continuity exists, control cable is shorted Replace cable.
b.
If continuity does not exist, notify higher level of maintenance for fuel sensor
replacement.
