Title (customer effect)
Fuel Injector Offset Learning Diagnostic Trouble Codes ( DTC ) / Fault Codes Logged
In Engine Control Module ( EMS ); Possible Rough / Uneven Idle - OBD15 Chassis
Cause
OBD15 chassis may set codes for injector offset learning minimum and maximum
values. The codes may be accompanied by rough idle, with no other performance
complaints or symptoms of injector failure.
Solution
Overview
Cylinder balancing is only active at idle speeds, between 500 and 750 RPM. The
balancing monitor does not run outside of this speed range, which means the codes do
not set under high idle or driving conditions. Offset codes generated with no other
injector-related codes and no symptoms aside from a possible rough idle may not
indicate a physical injector problem, and diagnosing the codes will in many cases lead
lead to no fault found. It has been determined that software may contribute to the
problem. Software improvements have been implemented to better control cylinder
balancing logic.
Relevant DTCs
The list of all applicable DTCs for this issue is included in the Fault Codes section below.
Repair
If any of the fault codes in the section below are set on an OBD15 engine:
A. Check the EMS Main Software (MSW) part number.
- If the EMS MSW part number is lower than 23167877.P01:
1. Update the EMS software
2. Reset Cylinder Balance from Premium Tech Tool (PTT) Operation 2387-0803-01 Cylinder Balancing, located in the Test tab.
3. Run a Cylinder Balance test from the same screen following the reset. Start
the test at minimum temperature (140 °F, 60 °C) and monitor balancing until
coolant temperature reaches approximately 177 °F (81 °C). This will allow
observation of performance during multiple engine modes that are entered during
warm-up.
4. If the Cylinder Balance test still shows an issue and/or there are one or more
Learning Offset codes that return following the update, follow Guided
Diagnostics for the applicable code or codes.
- If the EMS MSW is part number 23167877.P01 or newer, proceed with Guided
Diagnostics for the applicable code or codes.
