P1 ECM connector (P1-4) +Battery (P1-5) −Battery (P1-6) +Battery (P1-11) −Battery (P1-23) Keyswitch (P1-29) Digital return (P1-30) Analog return (P1-35) 8 V digital supply (P1-36) 5 V analog supplyTest Step 1. Inspect Electrical Connectors and Wiring
Turn the keyswitch to the OFF position.
Thoroughly inspect the ECM connectors J1/P1. Inspect all of the other connectors. Refer to Troubleshooting, "Inspecting Electrical Connectors" for the proper procedure for inspecting system wiring.
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 6.0 N m (55 lb in).
Check the customer connector (allen head screw) for the proper torque of 2.25 0.25 N m (20 2 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. The harness and wiring are free of corrosion, of abrasion, and of pinch points.Results:
OK - The harness and wiring are OK. Proceed to Test Step 2.
Not OK - There is a problem in the connectors and/or wiring.Repair: Repair the connectors or wiring and/or replace the connectors or wiring. Ensure that all of the seals are properly in place and ensure that the connectors are completely coupled.Verify that the repair eliminates the problem.STOPTest Step 2. Check the Voltage at the Battery Post
Measure the voltage at the battery posts.Expected Result:The voltage is 24 3 VDC.Results:
OK - The voltage is 24 3 VDC. Proceed to Test Step 3.
Not OK - The voltage is not 24 3 VDC.Repair: There is a problem with the batteries or the charging system. Refer to Testing and Adjusting, "Electrical System".STOPTest Step 3. Check the Voltage at the ECM Connector
Turn the keyswitch to the OFF position. The engine should be off.
Remove ECM connector J1/P1.
Turn the keyswitch to the ON position. The engine should be off.
Measure the voltage between P1-4 and P1-11 at the ECM connector P1.
Measure the voltage between P1-6 and P1-5 at the ECM connector P1.
Turn the keyswitch to the OFF position. The engine should be off.Expected Result:The voltage is 1 VDC from the voltage at the battery terminals.Results:
OK - The voltage is 1 VDC from the voltage at the battery terminals. The voltage at the ECM is OK. Proceed to Test Step 4.
Not OK - The voltage is not 1 VDC from the voltage at the battery terminals. The voltage is not correct at the ECM.Repair: There is an open circuit or excessive resistance in the wiring or connections between the batteries and the ECM. Verify that the breaker for the "ADEM II" is not tripped. Verify that the connection for the engine ground is clean and tight. Repair the connectors or wiring and/or replace the connectors or wiring.STOPTest Step 4. Check the Voltage at the Input for the Keyswitch at the ECM
Turn the keyswitch to the OFF position. The engine should be off.
Remove wire 113-OR from ECM connector P1-23.
Remove wire 229-BK from ECM connector P1-11.
Turn the keyswitch to the ON position. The engine should be off.
Measure the voltage between P1-23 and P1-11.
Turn the keyswitch to the OFF position. The engine should be off.
Reconnect all wires and connectors.Expected Result:The voltage is 24 3 VDC.Results:
OK - The voltage is 24 3 VDC.Repair: The problem may be intermittent. If the problem is intermittent, refer to Troubleshooting, "Inspecting Electrical Connectors" for the proper procedures for inspecting system wiring.STOP
Not OK - The voltage is not 24 3 VDC. Proceed to Test Step 5.Test Step 5. Check the Voltage at the Keyswitch
Turn the keyswitch to the ON position. The engine should be off.
Measure the voltage between terminal R and engine ground at the keyswitch.
Turn the keyswitch to the OFF position. The engine should be off.Expected Result:The voltage is 24 3 VDC.Results:
OK - The voltage measures 24 3 VDC. Proceed to Test Step 6.
Not OK - The voltage does not measure 24 3 VDC.Repair: Check for 24 3 VDC at terminal B of the keyswitch. If voltage is present on terminal B of the keyswitch, replace the keyswitch. If voltage is not present on terminal B of the keyswitch, verify that the breaker for the keyswitch is not tripped. Repair the wiring and/or terminals between the keyswitch and the Battery.STOPTest Step 6. Check the Voltage at the Main Power Relay
Turn the keyswitch to the ON position. The engine should be off.
Measure the voltage between the breaker for the VIMS and engine ground.
Turn the keyswitch to the OFF position. The engine should be off.Expected Result:The voltage is 24 3 VDC.Results:
OK - The voltage measures 24 3 VDC.Repair: Verify that the breaker for the VIMS is not tripped. Repair the wiring and/or connectors between the breaker for the VIMS and the input for the keyswitch at the ECM.STOP
Not OK - The voltage does not measure 24 3 VDC.Repair: Check for 24 3 VDC at the alternator circuit breaker. If voltage is not present at the alternator circuit breaker, repair the wiring between the alternator circuit breaker and the battery. If voltage is present at the main power relay from the alternator circuit breaker, check the wire to ground from the main power relay. If the wire to ground is okay, replace the main power relay.STOP
