DTC P0202 - Injector 2 Control Circuit
DTC P0204 - Injector 4 Control Circuit
This could have been caused by u testing the injector that is why they set by unpluging ,should have cleared codes drive it and scan again but i believe that what happens especially if unhooked injector #2 , because we were working on #4 so i expected to see P0204 but did unplug injector #2 ,let me know that is important
like i suspected there is P0300 multiple engine misfire
DTC P0354 - Ignition Coil 4 Control Circuit but remember you disconnected that plug with key on or running so it will set
DTC C0561 76 - System Disabled Information Stored Below Allowable Range Circuit/System Description The PSCM monitors vehicle speed validity message from the engine control module (ECM) via the serial data circuit. The power steering control module (PSCM) uses this vehicle speed message, along with the torque sensor and motor rotational sensor inputs, to determine the desired amount of steering assist. The PSCM monitors the intermediate voltage power limit request message from the accessory power module (APM) to detect a possible overheating event. The hybrid control module (HCM) sends this message to the PSCM via the serial data gateway module to reduce the APM power output to the PSCM until the APM returns to normal operating temperature. Conditions for Running the DTC Ignition ON. Conditions for Setting the DTC DTC C0561 71 The PSCM receives an invalid, vehicle speed message from the ECM. DTC C0561 76 The PSCM receives the intermediate voltage power limit request message to ramp down the power assist due to a possible APM overheating event. Actions Taken When DTC Sets * DTC is stored in memory. * The driver information center (DIC) displays the SERVICE POWER STEERING warning message. Conditions for Clearing the DTC * A current DTC will clear on the next malfunction free ignition cycle. * A history DTC will clear after 100 consecutive malfunction-free ignition cycles. * Steering assist is reduced.

did he clear your codes after the scan or no ?
P0300 is an issue of all your igntion coils are misfiring intermittently , this needs to be checked ,
the C0561 is when the power steering assist module picks up an erratic vehicle speed signal , like a bad wheel speed sensor , does your power steering feels heavy when the car acts up
we have to take care of the P0300
because it could be causing the C0561 do you have (service power steering message on the display
let me know
