Typical exampleNote: If a remotestart switch is installed, the remote start switch must be in the LOCAL position for this test. Test Step 1. Check for Connector Damage.
Turn the ECS to the OFF/RESET position.
Turn the circuit breaker for the battery to the OFF position.
Verify that the circuit breakers are not tripped.
Thoroughly inspect the ECM connectors J1/P1 and J2/P2. Inspect all of the other connectors. Refer to the diagnostic functional test Troubleshooting, "Inspecting Electrical Connectors" for details.
Perform a 45 N (10 lb) pull test on each of the wires in the ECM connector that are associated with the circuit.
Check the ECM connector (allen head screw) for the proper torque of 6 1 N m (53 9 lb in).
Check the harness and the wiring for abrasion and for pinch points.Expected Result:All connectors, pins, and sockets are completely coupled and/or inserted, and the harness and wiring are free of corrosion, of abrasion or of pinch points.Results:
OK - The connectors and wiring are okay. Proceed to Test Step 2.
Not OK - The connectors and/or wiring need repair.Repair: Repair the connectors or wiring and/or replace the connectors or wiring.STOPTest Step 2. Check the Voltage to the ECM.
Disconnect the primary ECM connector and the secondary ECM connector J1/P1.
Turn the circuit breaker for the battery to the ON position.
Turn the ECS to the STOP position.Note: Verify that wires D229(229) and wires A287(287) have continuity from the ECM(s) to the −Battery terminal.
Measure the voltage at the primary ECM and at the secondary ECM. Measure the voltage between P1-53 and P1-65. Measure the voltage between P1-52 and P1-63.
Measure the voltage between P1-70 and P1-65 at the primary ECM.
Measure the voltage between P1-70 and P1-65 at the secondary ECM.Expected Result:The voltage measures 24 3 VDC. The difference between the three voltage measurements is less than 0.5 VDC.Results:
OK - The ECM is receiving the correct battery voltage. Proceed to Test Step 5.
Not OK - P1-70 - The voltage is not 24 3 VDC on the input for the keyswitch to the ECM. Proceed to Test Step 6.
Not OK - The voltage is incorrect at the battery connections to the ECM(s). The wiring or components between the battery and the ECM are preventing the voltage from reaching the ECM. Proceed to Test Step 3.Test Step 3. Check the Battery Voltage.
Turn the circuit breaker for the battery to the OFF position.
Turn the ECS to the OFF/RESET position.
Measure no-load battery voltage at the battery terminals. Refer to Testing and Adjusting, "Test Tools for the Electrical System" for the proper procedures to check the batteries.
Load test the batteries. Use the 4C-4911 Battery Load Tester. Refer to the Operating Manual, SEHS9249. Refer to Special Instruction, SEHS7633.Expected Result:The no-load voltage at the batteries is at least 23.5 VDC and the batteries pass the load test.Results:
OK - The battery voltage is okay and the battery passes the load test. Proceed to Test Step 4.
Not OK - The battery voltage is incorrect and/or the battery fails the load test.Repair: The batteries or the alternator are causing the problem. Recharge the batteries or replace the batteries. Verify that the original condition is resolved. Refer to Testing and Adjusting, "Electrical System".STOPTest Step 4. Check the Voltage at Relay "R2" and/or Relay "R2A".
Turn the circuit breaker for the battery to the ON position.
Measure the voltage from wire A103(103) on terminal 87A of relay "R2" to the −Battery terminal. Measure the voltage from wire B103 on terminal 30 of relay "R2" to the −Battery terminal.
Measure the voltage from wire C150(150) on terminal 87A of relay "R2A" to the −Battery terminal. Measure the voltage from wire A150 on terminal 30 of relay "R2A" to the −Battery terminal.Expected Result:The voltage measures 24 3 VDC on all terminals.Results:
OK - The voltage is 24 3 VDC.Repair: Repair the wiring between relay "R2" and/or relay "R2A" and the ECM(s).STOP
Not OK - The voltage is not 24 3 VDC on terminal 30 of the ECM(s).Repair: Verify that voltage is present on wire A150 at the breaker for the primary ECM. If voltage is present at the breaker, repair the wiring between the breaker for the primary ECM and relay "R2A".Verify that voltage is present on wire B103 at the breaker for the secondary ECM. If voltage is present at the breaker, repair the wiring between the breaker for the secondary ECM and relay "R2".STOP
Not OK - The voltage is not 24 3 VDC on terminal 87A of the ECM(s).Repair: Verify that voltage is not present on wire T120 at the coil of relay "R2A". If voltage is present on wire T120, check all emergency stop switches for proper operation. Check for diagnostic codes for an engine overspeed. If voltage is not present on wire T120, replace relay "R2A".Verify that voltage is not present on wire T120 at the coil of relay "R2". If voltage is present on wire T120, check all emergency stop switches for proper operation. Check for a diagnostic code for an engine overspeed. If voltage is not present on wire T120, replace relay "R2".STOPTest Step 5. Check the Voltage at the Sensor Power Supplies.
Turn the ECS to the OFF/RESET position.
Disconnect the primary ECM connector P1/J1.Note: If you remove the sensor common from the ECM, an open circuit diagnostic code will be generated for all sensors that use the sensor common. Troubleshoot the original code. Delete the logged diagnostic codes when you are finished.
Check the analog supply voltage. Remove the wire 997 from P1-2. Remove the wire 993 from P1-3. Install wire jumpers into the sockets for the above wires.
Check the analog supply voltage. Remove the wire A997 from P1-18. Remove the wire A993 from P1-35. Install wire jumpers into the sockets for the above wires.
Check the digital supply voltage. Remove the wire 700 from P1-4. Remove the wire D998 from P1-5. Install wire jumpers into the sockets for the above wires.
Reconnect the primary ECM connector P1/J1.
Disconnect the primary ECM connector P2/J2.
Check the digital supply voltage. Remove the wire A700 from P2-56. Remove the wire F998
