ABS HU/CM INSPECTION
id041300198300
1. Disconnect the ABS HU/CM connector. (See ABS HU/CM REMOVAL/INSTALLATION [L.H.D.].) (See ABS HU/CM REMOVAL/INSTALLATION [R.H.D.].)
2. Connect the negative battery cable. (See BATTERY REMOVAL/INSTALLATION [ZJ, ZY].) (See BATTERY REMOVAL/INSTALLATION [MZ-CD 1.4 DI Turbo].) (See BATTERY REMOVAL/INSTALLATION [MZ-CD 1.6 (Y6)].)
3. Attach the tester lead to the ABS HU/CM wiring harness-side connector and inspect the voltage, continuity, or resistance according to the standard (reference value) in the table below.
