Abs-2: Open Isolation Solenoid Circuit
- Turn ignition off. Disconnect negative battery cable. Disconnect ABS control module harness connector.
- Using ohmmeter, measure resistance between terminal "C" of ABS control module harness connector and chassis ground. See Fig 1. If resistance is 3-6 ohms, replace ABS control module. If resistance is greater than 6 ohms, go to next step.
- Disconnect solenoid valve harness connector. Using ohmmeter, measure resistance between isolation solenoid terminal (Orange/White wire) and ground terminal (Black wire) of solenoid valve. See Fig 2.
- If resistance is 3-6 ohms, repair open in isolation solenoid wire between solenoid valve and ABS control module. Check for dirty or loose terminals. If resistance is greater than 6 ohms, replace hydraulic unit.
