Imported Cars & Light Trucks & Vans -> 1998-2000 -> Leak Test -> Electronic Leak Detectors -> Fluid Leak Detectors
Vehicle: 1998 Volvo S70 2.4 L5 GAS
Testing the refrigerant system for leaks is one of the most important phases of troubleshooting. One or more of the methods outlined will prove useful in detecting leaks or checking connections if service work is performed. Before beginning any leak test, attach a manifold gauge set and note pressure. If little or no pressure is indicated, a partial charge must be installed.

The control unit contains a monitoring circuit to detect any internal faults in the control unit and any electrical faults in the sensors, hydraulic modulator or signaling system.
If a fault occurs, the control unit disengages the ABS and illuminates a warning light. When the warning light comes on, a complete fault tracing procedure should be followed. The fault tracing procedure assumes that the standard braking system is fully operational.
