DTC 17F-12-Missing adjustment value programming for injector in
cylinder 1
Control Module : ECU
Context:
The Engine Control Unit (ECU) A-9000 uses an IMA code to correct fuel trim for each fuel injector equipped with the
engine at every key ON. If the ECU A-9000 determines that this trim correction for fuel injector number 1 Y-9001 can
not be performed, this fault will occur. For more information about how to configure injector IMA codes, see Fuel
injectors - Configure - IMA codes (10.218).
Cause:
The ECU A-9000 has determined that the fuel injector number 1 Y-9001 fuel trim correction can not be performed.
Solution:
1. Use the Electronic Service Tool (EST) ensure that the correct IMA code is programmed to fuel injector number 1
Y-9001.
A. If the correct code is not programmed. Use the EST to program the correct code.
B. If the correct code is programmed, continue to Step 2.
NOTE: The IMA code may be under the paint on the fuel injector.
2. 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.
