YES: write down all code numbers and do the DTC CHECK
NO: the DTC can not help you finding the problem.

(2) IF it is flashing and the flash is 0.2 seconds ON and 0.2 seconds OFF (Fig. 7A-8), this means that you should have a DTC stored. Please recheck GO TO DIAGNOSTIC CHECK and if you find the same problem, replace Powertrain Control Module (PCM).
