5. Using digital multimeter (WP
1.
If continuity is NOT found, replace
0296), test for continuity between
instrument panel harness
PINK WIRE on instrument panel
(WP 0260). Ensure all harness

instrument panel harness
pin 13 on dash monitor connector
(WP 0260). Ensure all harness
E-C7 (WP 0018, Figure 5) and all
connectors are reconnected. Ver-
other pins in dash monitor con-

2.
If continuity is NOT found, replace
dash monitor ECM (WP 0262).
Ensure all harness connectors
are reconnected. Verify correct
operation of machine (TM 5-2410-
241-10).
