Hi Everyone, Last year I posted that my car displayed 'Check Parking Brake / VSC' which following check at the garage the error message 'fault on the Injector (No.1)' Error code  P063D. Through advice, I had the No.1 Injector replaced (Toyota advice was to replace all 4 injectors) 11 months on, the fault code re-appeared and following a garage assessment the following error codes were detected: P062D - No.1 Fuel Injector Driver Circuit Performance / C1201 -Engine Control system
