CAN DATA LINK CIRCUIT TEST CONTINUED
10. Using digital multimeter, test CAN- circuit K990-GN for continuity between engine ECM harness connector FA-
C17 (Figure 9, Item 1) terminal 21 (Figure 9, Item 2) and transmission ECM harness connector FA-C21 (Figure
9, Item 3) terminal 68 (Figure 9, Item 4). Resistance should be less than 5 ohms.
a. Continuity - proceed to step 11.
b. No Continuity - harness is open, replace rear main harness (WP 0188).
