Re: re
Saw this in another thread. This suggests that if the ABS light sequence does not follow the correct sequence the car will fail its MOT.
Views anyone?

The Testers Manual
3.4 Anti-Lock Braking Systems
Information Method of Inspection Reason for rejection
This ABS inspection applies to all systems fitted as 'standard', and to 'optional' systems fitted.
When testing vehicles that have ABS fitted the road wheels should not be allowed to rotate clear of the standing surface with the ignition on as this can cause the ABS system to indicate a fault which may require specialist equipment to rectify
Missing components
Where a vehicle is presented for test with an ABS component obviously missing but, follows the correct sequence of operation, the defect must be brought to the attention of the presenter.
If the vehicle is fitted with an anti-lock braking system, check that
a. a warning lamp is fitted
b. the lamp illuminates
c. the lamp follows the correct sequence of operation
d. does not indicate a fault.
REASONS FOR REJECTION
Note: The sequence varies with the type of system. Refer to the manufacturers or other reliable data, eg purpose produced charts, books, etc. 1. The warning lamp
a. is missing
b. does not illuminate
c. does not follow the correct sequence
of operation
d. indicates an ABS fault.
