Left Front Hydraulic Modulator Inlet Valve Resistance Test

Using an ohmmeter, measure resistance between ECU connector terminals No. 11 and 35. See Figure . If resistance is 5-7 ohms, go to next test. If resistance is not 5-7 ohms, measure between hydraulic modulator terminals No. 1 (Brown wire) and 7 (Blue or Black/Green wire). See Figure thru Figure . If resistance is 5-7 ohms, check wiring between valve block and ECU for open circuit. If resistance is not 5-7 ohms, replace hydraulic modulator.
