Troubleshooting Test Steps Values Results
1. Check for Codes
A. Connect Cat® Electronic Technician (ET) to the service tool connector.
B. Look for active codes that are associated with the system for the event code.
Codes
Result: An associated code is active.
Repair: Troubleshoot any associated codes before continuing with this test.
Result: A code is active or logged.
Proceed to Test Step 2.
2. Inspect the Driven Equipment
Driven Equipment
Result: The driven equipment is OK.
Proceed to Test Step 3.
Result: The driven equipment is NOT OK.
Repair: Repair or replace damaged driven equipment.
Proceed to Test Step 3.
3. Inspect the Batteries
A. Charge the batteries, if necessary. Refer to Special Instruction, SEHS7633, "Battery Test Procedure" for additional information.
B. Load-test the batteries. Refer to Special Instruction, SEHS9249, "Use of 4C-4911 Battery Load Tester for 6, 8 V and 12 V Lead Acid Batteries" for additional information.
Batteries
Result: The batteries are OK.
Proceed to Test Step 4.
Result: The batteries are NOT OK.
Repair: Repair or replace the batteries.
Proceed to Test Step 4.
4. Check for Slow Cranking Speed
A. Connect Cat ET.
B. Use Cat ET to monitor the following while cranking the engine:
- Engine speed
Note: If the engine cranks too slowly, the engine will not start.
C. Check for the following problems:
- Low voltage for an electric starting system
- Excess parasitic load
- Engagement all starters on a multiple starting motor system
- Starting signal being sent from controller
Cranking Speed
Result: The engine speed is greater than 100 rpm for a duration of four revolutions.
Proceed to Test Step 5.
Result: The engine speed is not greater than 100 rpm for a duration of four revolutions.
Repair: Repair or replace the damaged components.
Proceed to Test Step 5.
5. Check the Starting Aids (if Equipped)
A. Ensure that the ether canister is not empty or low.
B. Check for proper operation of the jacket water heater.
Ether and Heater
Result: All starting aids checked out OK.
Proceed to Test Step 6.
Result: A starting aid checked out NOT OK.
Repair: Repair or replace damaged starting aid components.
Proceed to Test Step 6.
6. Check the Keyswitch Power to the Electronic Control Module (ECM)
A. Turn the power supply ON.
B. Check the voltage supply to the engine ECM on the keyswitch circuit. Refer to the appropriate wiring schematic for details on the pins.
18 V
Result: The keyswitch power is greater than 18 VDC.
Proceed to Test Step 7.
Result: The keyswitch power is less than 18 VDC.
Repair: Refer to Troubleshooting, "Electrical Power Supply - Test" for additional information.
Proceed to Test Step 7.
7. Check the ECM Supply Voltage
A. Check the battery supply voltage between each ECM battery + pin and each ECM battery – pin on the engine ECM. Refer to the appropriate wiring schematic for details on the pins.
18 V
Result: The supply voltages are greater than 18 VDC.
Proceed to Test Step 8.
Result: The supply voltages are less than 18 VDC.
Repair: Refer to Troubleshooting, "Electrical Power Supply - Test" for additional information.
Proceed to Test Step 8.
8. Inspect the Fuel System
A. Visually check the fuel level in the tank. Do not rely on the fuel gauge only.
B. Ensure that the fuel vent is not filled with debris.
C. Ensure that the fuel supply valve (if equipped) is in the OPEN.
Note: Cold weather adversely affects the characteristics of fuel. Refer to Operation and Maintenance Manual for information on improving the characteristics of the fuel during cold-weather operation.
D. Check the fuel quality. Check the fuel tank for debris or foreign objects which may block the fuel supply.
E. Check for external fuel leaks.
F. Check all fuel fittings to ensure the correct torque values.
Fuel System
Result: The fuel system is OK.
Proceed to Test Step 9.
Result: There was a problem found during the fuel system inspection.
Repair: Repair or replace the damaged fuel system components.
Proceed to Test Step 9.
9. Check the Fuel Priming System
A. Connect Cat ET.
B. Prime the fuel system. Refer to the Original Equipment Manufacturers (OEM) and Operation and Maintenance Manual (OMM) for additional information.
C. Verify the "Fuel Transfer Pump Intake Pressure" is reading greater than 400 kPa
