Code YDRAX4_PTV on a 2013 DRIVE PTV points to the fuel-injected car, and the service book for it is LIT-19616-JC-01.
This volume was written for the whole Drive family across 2010 to 2013, which means the injection system, the carburetted engine and the 48-volt DC motor cars all appear between the same covers. In practice that is an advantage when tracing a shared circuit or a common chassis fastener.
For an EFI car the material worth having is the injection diagnosis: sensor values, fuel pressure, the injector and throttle body, and the fault codes with the checks that follow each one. Around that sit engine service, the clutch and belt, transaxle, brakes, steering, suspension and the complete wiring diagrams, all with factory torque figures.
Verify YDRAX4_PTV before purchase. The EFI and CARB Drive cars look alike from outside and are not serviced the same way at all.
