1-800-343-7357. Engine Protection and Diagnostics The NORAM 65E grader uses amber and red warning lights to signal the operator when the engine elec- tronic control module (ECM) detects an engine fault or problem. Depending on the severity of the engine problem, the ECM may decrease engine power or shut the engine down after warning the operator with flashing warning lights.
Page 19: Diagnostics
Section 1 65E Turbo Motor Grader Engine Service Manual Diagnostics Using the engine warning lights, engine fault codes may be retrieved from the engine ECM using the follow- ing procedure: Step 1: Turn the key switch to the “OFF” position.
