STOREDINVALID VEHICLE SPEED MULTIPLEX SIGNAL
1.DEF: Inconsistency of the signal
NOTESIf the following faults are present or stored, deal with them first:
–DF240 Invalid front right-hand wheel speed multiplex signal.
–DF241 Invalid front left-hand wheel speed multiplex signal.
–DF242 Invalid rear right-hand wheel speed multiplex signal.
–DF243 Invalid rear left-hand wheel speed multiplex signal.
Run a multiplex network test (see 88B, Multiplex).
If the fault is still present, carry out fault finding on the system (see 38C, ABS).
If the problem is still present, contact the Techline.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition and carry out a road test followed by a test with the diagnostic
tool.
