CAN DATA LINK CIRCUIT TEST CONTINUED
21. Using digital multimeter, test continuity of CAN- circuit K990-GN between Implement #1 ECM harness connec-
tor P-C39 (Figure 16, Item 2) terminal 68 (Figure 16, Item 3) and harness connector P-C69 (Figure 16, Item 4)
terminal 8 (Figure 16, Item 5). Resistance should be less than 5 ohms.
a. Continuity - proceed to step 22.
b. No Continuity - harness is open, replace lower cab harness (WP 0266).
22. Using digital multimeter, test continuity of CAN- circuit K990-GN between Implement #2 ECM harness connec-
tor P-C27 (Figure 16, Item 1) terminal 68 (Figure 16, Item 6) and harness connector P-C69 (Figure 16, Item 4)
terminal 8 (Figure 16, Item 5). Resistance should be less than 5 ohms.
a. Continuity - proceed to step 23.
b. No Continuity - harness is open, replace lower cab harness (WP 0266).
23. Using digital multimeter, test continuity of CAN- circuit K990-GN between AWD ECM harness connector P-C37
(Figure 16, Item 7) terminal 68 (Figure 16, Item 8) and harness connector P-C69 (Figure 16, Item 4) terminal 8
(Figure 16, Item 5). Resistance should be less than 5 ohms.
a. Continuity - proceed to step 24.
b. No Continuity - harness is open, replace lower cab harness (WP 0266).
