4 WHEEL ANTILOCK BRAKE SYSTEM (4WABS)

Z-112wiring diagramUnverified

Header notes '(( ))...CANADA' and '< >...K8 DOHC' indicate the double-bracketed callouts apply to Canada-spec and angle-bracketed to K8 DOHC vehicles. Dense full-page diagram; some pin-grid cells in the bottom connector tables are low-contrast.
