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
A. Inspect the equipment being driven by the engine.
B. Check any damage to the components or the linkage between the engine and 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.
If the problem is not resolved, 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.
Inspect the charging system circuit to verify that the charging system is working. Verify that the alternator is working charging the batteries.
If the problem is not resolved, proceed to Test Step 4.
4. Check for Slow Cranking Speed
A. Connect Cat ET to the service tool connector.
B. Use Cat ET to monitor the following when cranking the engine:
- Engine speed
Check to make sure that the engine cranking speed is greater than 100 RPM.
Engine speed
Result: The engine speed is greater than 100 RPM.
Proceed to Test Step 5.
Result: The engine speed is less than 100 RPM.
Check for the following problems:
- Low voltage for an electric starting system
- Low air pressure for an air start system
- Excess parasitic load
- Engagement all starters on a multiple starting motor system
- Hydraulic starters and the supply pump
- Starting signal being sent from controller
Repair: Repair or replace the damaged components.
If the problem is not resolved, 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 are functioning.
Proceed to Test Step 6.
Result: One or more of the starting aids is not functioning correctly.
Repair: Repair or replace damaged starting aid components.
If the problem is not resolved, 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.
If the problem is not resolved, 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.
ECM Power Supply
Result: The battery supply power is greater than 18 VDC to all ECM pins.
Proceed to Test Step 8.
Result: The battery supply power is less than 18 VDC on one or more pins.
Repair: Refer to Troubleshooting, "Electrical Power Supply - Test" for additional information.
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 full OPEN position.
Note: Cold weather adversely affects the characteristics of fuel. Refer to Operation and Maintenan
