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.
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.
