TROUBLESHOOTING WITH A DIAGNOSTIC CODE - CONTINUED
Table 2. Machine Control System - Continued.
TEST OR INSPECTION
CID FMI CODE
1. Inspect harness connections. Refer to
1. If wiring harness connectors are tight
Electrical Connectors Inspection (WP 0022
and free of corrosion, go to Test 2.
2. If wiring harness connectors are in need
(a) Turn battery disconnect switch to OFF
of repair, replace wiring harness in
question (WP 0169 00 thru WP 0175
(b) Inspect all harness connections related
sure connectors are clean and tight.
(c) Check connectors for proper mating.
Ensure all seals are present and in
(d) Check harness for signs of damage or
(e) Check wires at connector. Ensure wires
are secured tightly into connector. Take
care not to pull wire out of connector.
(f) Check exposed wires at connectors for
nicks or signs of abrasion.
(g) Check for moisture inside connector.
(h) Check connectors for dirty or corroded
(i) Check each pin and socket of wiring
harness connectors. Ensure contacts
are properly installed. Contacts should
mate correctly when two pieces of
connector are placed together.
2. Check for shorts to ground.
(a) Battery disconnect switch remains in
Ohms, go to Test 3.
(b) Disconnect wiring harness connectors
there is a short between frame ground
from all ECMs that use CAN data link
and contacts J2-67 (wire F711 GN) and
(WP 0052 00 and WP 0053 00).
J2-68 (wire F712 GY) of data link
(c) At wiring harness for machine ECM,
circuit in wiring harness. Replace
measure resistance between frame
wiring harness in question (WP 0169
ground and connector contacts J2-67
00 thru WP 0175 00).
(wire F711 GN) and J2-68 (wire F712
GY) of data link circuit.
