DTC P1676:00 [SKYACTIV-D 1.5]

id0102q2149900

DTC P1676:00

Fuel injector code mistakenly programmed

DETECTION CONDITION

•  The fuel injector identification number is mistakenly programmed into the PCM for a continuous 1 s when the following condition is met.

MONITORING CONDITIONS

―  Ignition switched ON (engine off or on)

Diagnostic support note

•  This is a continuous monitor (CCM).

•  The check engine light illuminates if the PCM detects the above malfunction condition during the first drive cycle.

•  FREEZE FRAME DATA/Snapshot data is available.

•  DTC is stored in the PCM memory.

FAIL-SAFE FUNCTION

•  Limits the engine torque or the upper limit of the engine speed.

•  Inhibits the auto DPF regeneration control.

•  Fully open the intake shutter valve.

•  Inhibits the compulsory DPF regeneration control.

•  Inhibits the EGR control.

•  PCM restricts engine-transaxle integration control. (ATX)

•  Inhibits engine-stop by operating the i-stop function.

POSSIBLE CAUSE

•  Fuel injector code program is not performed correctly.

•  PCM malfunction

Diagnostic Procedure

STEP	INSPECTION		ACTION
1	RECORD VEHICLE STATUS AT TIME OF DTC DETECTION TO UTILIZE WITH REPEATABILITY VERIFICATION Note • Recording can be facilitated using the screen capture function of the PC. • Record the FREEZE FRAME DATA/snapshot data on the repair order.	—	Go to the next step.
2	VERIFY RELATED SERVICE INFORMATION AVAILABILITY • Verify related Service Information availability. • Is any related Service Information available?	Yes	Perform repair or diagnosis according to the available Service Information. • If the vehicle is not repaired, go to the next step.
2		No	Go to the next step.
3	PERFORM FUEL INJECTOR CODE PROGRAM • Perform the “FUEL INJECTOR CODE PROGRAM”. (See FUEL INJECTOR CODE PROGRAM [SKYACTIV-D 1.5].) • Is the fuel injector code programmed correctly?	Yes	Go to the next step.
3		No	Perform the “FUEL INJECTOR DATA RESET”. (See FUEL INJECTOR DATA RESET [SKYACTIV-D 1.5].) Perform the “FUEL INJECTOR CODE PROGRAM” again. (See FUEL INJECTOR CODE PROGRAM [SKYACTIV-D 1.5].) Go to the next step.
4	VERIFY DTC TROUBLESHOOTING COMPLETED • Clear the DTC from the PCM memory using the M-MDS. (See CLEARING DTC [SKYACTIV-D 1.5].) • Perform the DTC Reading Procedure. (See ON-BOARD DIAGNOSTIC TEST [SKYACTIV-D 1.5].) • Is the same DTC present?	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [SKYACTIV-D 1.5].)
4		No	Go to the next step.
5	VERIFY AFTER REPAIR PROCEDURE • Perform the “AFTER REPAIR PROCEDURE”. (See AFTER REPAIR PROCEDURE [SKYACTIV-D 1.5].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [SKYACTIV-D 1.5].)
5		No	DTC troubleshooting completed.
