9-5 Linear Sport Wagon (9600) L4-2.3L Turbo (B235) (2002)
The control module receives a continuous power supply from the +30 circuit and is designed for a working voltage of between 9 and 16 V.
When the ignition key is turned to ON, the control module is energized and the ABS warning light comes on as part of the function test. If the system
is OK, the light will go off after 3-5 seconds.
Always ground yourself, e.g. on the engine block, before touching the control module and avoid touching the terminal pins.
The control module incorporates the following components:
-
Main relay
-
Pump relay
Main relay
The integral main relay supplies power to the solenoid valves and pump relay and cannot be replaced separately.
Pump relay
The integral pump relay supplies power to the return pump and cannot be replaced separately.
Diagnostics
The control module monitors its own internal functions and the other ABS-system components.
If an internal fault occurs in the control module, diagnostic trouble code C1605 will be generated, the ABS warning light will come on and the ABS
system will be disabled.
