General Description

There are two transformer for injector operation in side of ECM. 1 pilot and 1 main injection are operated by ECM in EURO 3 diesel engine therefore one transformer device is sufficient to control injector however, 2 pilot and if CPF is applied, 2 post injection are performed additionally by ECM in EURO 4 diesel engine thus, two transformer is required.

DTC Description

P062D is set when the problem of transforming system 1 for injector contol occurs. This code is due to the failure of transforming system inside of ECM.

※If battery voltage is low, this code can be set. Therefore, beforehand, check DTC code relevant to battery voltage and charging system.

Component Inspection
1.

ECM Component Inspection

(1)

IG KEY "OFF", ENGINE "OFF".

(2)

Disconnect ECM.

(3)

Replace ECM, check if abnormal operations disappear.

(4)

If problems are corrected, replace ECM.

note

Input injector IQA data(7 letters) using GDS at replacing ECM.

Enter the driving distance - how many km the CPF is used- into New ECM with scanner.

For immobilizer applied vehicle, input pin code.

Verification of Vehicle Repair

After a repair, it is essential to verify that the fault is corrected.

1.

After connecting GDS select "Diagnostic Trouble Codes(DTCs)" mode to and then clear DTC.

2.

Drive the vehicle within DTC Enable conditions in General information.

3.

After selecting "Diagnostic Trouble Codes(DTCs)" mode and check DTC is recorded again.

4.

Are any DTCs recorded ?

▶ Go to the DTC guide of recorded NO. in GDS

▶ System operates within specification.
