Information:
Which Generate This Code:This diagnostic code is recorded when the Product Link detects a battery voltage of less than 11 DCV.Determine if a battery charger or a welder is being used on the machine. Disconnect the charger or the welder if one is used. Recheck for the diagnostic code. Check the charging system if the diagnostic code is still active.Test Step 1. CHECK THE SYSTEM VOLTAGE AT THE PRODUCT LINK.Start the engine and operate the engine at a high idle. Measure the system voltage between the +battery and -battery contacts.Expected Result:The voltage is 27 DCV to 29 DCV for a 24 DCV system. The voltage is 13 to 15 DCV for a 12 DCV system.Results:
OK - The voltage is correct. Clear the diagnostic code and check for a reoccurrence of the diagnostic code. Stop.
NOT OK - The voltage is incorrect. 2Test Step 2. CHECK THE ALTERNATOR.Run the engine at a high idle for several minutes. Measure the voltage output at the battery posts.Expected Result:The voltage should be 27 DCV to 29 DCV for a 24 DCV system. The voltage should be 13 to 15 DCV for a 12 DCV system.Results:
OK - The voltage is correct. Proceed to Test Step 3
NOT OK - The voltage is incorrect.Repair: Repair or replace the alternator. Stop.Test Step 3. CHECK THE BATTERY VOLTAGE.Turn the key start switch to the OFF position. Measure the battery voltage at the battery posts.Expected Result:The voltage should be 12 to 15 DCV for a 12 DCV system. The voltage should be 24 to 27 DCV for a 24 DCV system.Results:
OK - The voltage is between 12 and 15 DCV (or 24 to 27 DCV).Repair: The Product Link could be faulty. Recheck the system before replacing the Product Link. The Product Link is seldom the cause of a diagnostic code. Refer to Testing And Adjusting, "Electronic Control Module (ECM) - Replace". If the Product Link has been replaced recheck the system and check the status of the diagnostic code. Stop.
NOT OK - The voltage is not between 12 and 15 DCV or 24 and 27 DCV.Repair: See Special Instruction, REHS0354, "Charging System Troubleshooting". If conditions are not resolved, the Product Link could be faulty. Recheck the system before replacing the Product Link. The Product Link is seldom the cause of a diagnostic code. Refer to Testing And Adjusting, "Electronic Control Module (ECM) - Replace". If the Product Link has been replaced recheck the system and check the status of the diagnostic code. Stop.
