Test No. 3: Abs Warning Light Does Not Illuminate: Condition
WARNING: This page is about a different car, the 2002 Hyundai XG350. However, it is still accessible from the selected car via links, so may be relevant.
When current flows in the Hydraulic and Electronic Control Unit (HECU), ABS relay turns from On to Off as initial check. HECU illuminates ABS warning lamp, when ABS relay is off, even if there is a problem with circuit between ABS warning light and HECU. If ABS warning light does not illuminate, cause may be an open circuit in ABS warning light power supply circuit, a blown bulb, an open circuit in both circuits between ABS warning light and HECU and in circuit between ABS warning lamp and ABS relay. Possible causes are:
- Blown fuse.
- Burnt out ABS warning light bulb.
- Wiring harness or harness connector malfunction.
