This is a basic wiring diagram for a ABS D system, some ECU’S in this range may differ slightly. The ECU numbers this diagram applies to are as follows:

( all numbers start with 446 004 …) 302. 304. 305. 306. 307. 308. 309. 310. 311. 312. 313.

14. 315. 316. 317. 318. 319. 320. 322.

To manually start the ABS Blink code connect a wire to Pin 15 then to an external bulb (max 24 volt 5 watt) then to a live feed (possibly pin 7) then short pin 15 to ground via a switch for 3 seconds to start the blink code
