|5.||Using a voltmeter, measure the voltage between the battery terminals. Compare the voltage measured at the battery with the voltage shown in the ABS DATA LIST with the HDS.|
Is the voltage difference 3 V or more?
YES - Replace the ABS modulator-control unit: Except K20Z2 engine model, K20Z2 engine model.n
NO - Check the battery, and do the alternator regulator circuit troubleshooting: R18A1 engine model, K20Z2 engine model. Also check for loose terminals in the ABS modulator-control unit 25P connector. If necessary, substitute a known-good ABS modulator-control unit, and retest: Except K20Z2 engine model, K20Z2 engine model.n
