CAN DATA LINK CIRCUIT TEST CONTINUED
9. Using digital multimeter, test continuity of CAN- circuit K990-GN between the engine ECM harness connector
FA-C17 (Figure 8, Item 1) terminal 21 (Figure 8, Item 2) and harness connector FA-C22 (Figure 8, Item 4)
terminal 8 (Figure 8, Item 3). Resistance should be less than 5 ohms.
a. Continuity - proceed to step 10.
b. No Continuity - harness is open, replace rear main harness (WP 0188).
