Electrical systems - FAULT CODES
DTC 45A-03-Error in comparing energizing time to maximum value
for injector in cylinder 3
Control Module : ECU
Context:
The Zero Fuel Calibration (ZFL) evaluates energizing time for injectors at low idle. The ZFL uses learned calibration
values to change the energizing time of the pilot fuel injection. If the Engine Control Unit (ECU) A-9000 determines
that there is an error during this process, this fault will occur.
Cause:
The ECU A-9000 has determined that there is an error in the ZFL process for fuel injector number 3 Y-9003.
Solution:
1. Verify that the correct IMA injector code has been programmed to injector number 3.
A. If the correct IMA code is present, continue to Step 2 .
B. If the correct IMA code has not been uploaded, program the correct IMA code.
NOTE: The IMA code may be under the paint on the fuel injector.
NOTE: For more information regarding programming IMA codes, see Fuel injectors - Configure - IMA codes
(10.218) .
2. Replace the fuel injector number 3 Y-9003.
Use the Electronic Service Tool (EST) to verify the status of this fault.
A. If the fault has been resolved, return the machine to service.
B. If the fault has not been resolved, continue to Step 3 .
3. Check the ECU A-9000 for the appropriate software and re-flash, if necessary.
A. If the fault has been resolved, return the machine to service.
B. If the fault has not been resolved, escalate an ASIST concern.
