25. Using digital multimeter (WP
1. If continuity is found, replace
0296), test for continuity between
steering control harness (WP
pin 20 on powertrain ECM 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-
