2004 Infiniti Q45FACTORY OEM SERVICE PROCEDURE

ABS System

If a malfunction occurs in electrical system, ABS warning lamp, VDC OFF indicator lamp, and SLIP indicator lamp in combination meter turn ON. In this condition, fail-safe function puts VDC/TCS/ABS and EBD into one of following conditions.

  1. Only EBD operates. Same condition as that of models without VDC/TCS/ABS.
  2. VDC/TCS/ABS and EBD do not operate. All 4 wheels operate as normal brakes.
NOTE: In step 1 shown above, self-diagnosis when ignition switch is turned ON and when vehicle starts at initial time is carried out. ABS self-diagnosis noise may be heard as usual.
