Code and Description Conditions which Generate this Code System Response
E043(1) Low System Voltage Warning The battery supply voltage is less than 20 VDC for ten seconds. The code is logged.
168-0 Electrical System Voltage high - most severe (3) The battery supply voltage is greater than 32 VDC for 0.5 seconds.
The engine is not being cranked.
168-1 Electrical System Voltage low - most severe (3) The battery supply voltage is less than 18 VDC for 0.5 seconds.
The engine is not being cranked.
168-2 Electrical System Voltage erratic, intermittent, or incorrect The engine is running but not cranking. The battery supply voltage is less than 18 VDC for at least .06 seconds. Three times in the last seven seconds, the battery supply voltage was less than 18 VDC. The engine has a Primary ECM and a Secondary ECM. The electrical power to the primary ECM comes through the breaker for the primary ECM and the contact of relay "R2A". The electrical power to the secondary ECM comes through the breaker for the secondary ECM and the contact of relay "R2". Power goes to pin P1-53 and pin P1-52 of the ECM(s). The −Battery comes through the breakers for the primary ECM and the secondary ECM. The −Battery connects to pin P1-63 and pin P1-65 of the ECM(s). The Engine Control Switch (ECS) sends a signal to pin P1-70 on the primary ECM and to pin P1-70 on the secondary ECM when the ECS is in the following positions: REMOTE, STOP and START. When the primary ECM senses battery voltage on pin P1-70 of the primary ECM, the primary ECM will power up. When the secondary ECM senses battery voltage on pin P1-70 of the secondary ECM, the secondary ECM will power up. When the ECS is in the OFF/RESET position, voltage is not present on these inputs and the ECM(s) will power down.If an emergency shutdown occurs, circuitry will energize relay "R2" and relay "R2A". When these two relays are energized the contacts of the relays will open. When the contacts of the relays open, battery power is removed from the ECM(s).In order to restart the engine, the operator must correct the cause of the emergency shutdown. The Engine Control Switch (ECS) must be turned to the OFF/RESET position. This resets the electrical circuits in the circuit. In addition to turning the ECS to the OFF/RESET position, the operator must manually open the air shutoff valves before starting the engine.The presence of two +Battery connections and two −Battery connections to the ECM reduce harness resistance. All of these connections must be complete in order to ensure proper engine operation.

Turn the ECS to the OFF/RESET position.
Turn the circuit breaker for the battery to the OFF position.
Thoroughly inspect the ECM connectors J1/P1 and J2/P2. Refer to Troubleshooting, "Electrical Connectors - Inspect" 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. Refer to Troubleshooting, "Electrical Connectors - Inspect" for details.
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 OK. 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. Ensure that all of the seals are properly in place and ensure that the connectors are completely coupled.STOPTest Step 2. Check the Voltage to the ECM
Disconnect the primary ECM connector J1/P1 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.
Measure the voltage between the following pins on the primary ECM and on the secondary ECM.
P1-52 and P1-63
P1-53 and P1-65
P1-70 and P1-65Expected Result:The voltage measures 24 3 VDC. The difference between the three voltage measurements is less than 0.5 VDC.Re
