Test Point 1

Test point 1
PDAS diagnosis with system tester 9288

If a fault is indicated by the PDAS/ABS warning lamp (No.8/No.9) and irregularities are suspected, first read out the fault memory of the PDAS/ABS control unit.

If No.13 (brake pressure warning lamp) and No.8 light up although the engine has been running for longer than 1 minute, there is a fault in the booster circuit (test point 6 or troubleshooting in accordance with circuit diagram).
