Corrective Actions
1. Check For Additional Alarms: If this alarm is activated in conjunction with other alarms (00041 Engine Stalled, 05012 Check ENCU Power Circuit, 00078 Check SV1 Circuit, 00079 Check SV4 Circuit, 05013 Check Clutch Circuit, 00085 Check UL1 Circuit or 00086 Check UL2 Circuit) check F5 and F10. Fuses must be good. Replace fuse(s) as required. Clear alarms, restart and check for repeat alarm(s). 2. Check For Low Fuel Level: Add fuel as needed to the fuel tank. 3. Check for Alarms: Check for 00040 Check Engine Preheat Circuit and 00035 Check Starter Circuit. Alarm conditions must be corrected and the alarm cleared to continue. 4. Check Engine Control Unit (ENCU) and Fuel Speed Actuator (FSA) a. Check voltage from fuse F3 through PCM-34 and SP-6 to ENCU-22. Verify correct fuse, see Figure 1.7. Must have minimum 11 VDC with the battery connected and SROS in the OFF position. b. Check voltage from 3MM-9 to ENCU-44. Must have minimum 11 VDC with SROS in the START/ RUN position. If not, energize the run relay output using Component Test mode (refer to Section 1.2.4) and retest. c. Check for ground at ENCU-19 and ENCUGND-A (at the battery negative cable connection). If ground not good, check connectors and wiring between terminals for damage, moisture or corrosion. d. Inspect fuel/speed actuator (FSA), engine speed sensor (ENSSN) and engine speed control unit (ENCU) connector pins and terminals. Verify no physical damage to components, and no damage or corrosion in connectors. e. Check resistance and amp draw of FSA. Refer to Section 1.11 for specifications. f. Check FSA plunger. Must move in and out freely. Refer to engine manual. 5. Check Engine Air-intake System a. Check air cleaner indicator. Flag must not be visible. b. Inspect air intake system. Verify hoses and tubes in good condition, with no kinks or restrictions. 6. Check For Correct Engine Oil: Check viscosity is correct for ambient conditions. Refer to Section 1.8. 7. Check Engine Exhaust System: Exhaust system must be clear and unobstructed. 8. Check Engine Compression: Refer to Engine Workshop manual.
