You need to bridge the black and black/pink wires on the diagnostic plug.
Remove ABS warning light realy. (Left hand relay under passenger seat. Green Base.)
Turn on ignition.
ABS light will come on. After five seconds it will start to flash.
The flashes consist of a pause, a flash a pause and a pause.
Then there will be a pause of 2.5 seconds followed by a series of flashes. This will be the first part of the code. then there will be another pause of 2.5 seconds then another series of flashes forming the second part of the code.
Fault code will continue to flash over and over again unil bridge wire is removed. Once the bridge wire is remove the fault code will be cleared from memory.
re insert wire to get another code if there is one.
Fault codes are.
2-12 front right
2-13 rear left
2-14 front left
2-15 rear right.
Too largean air gap or sensor has been forced out by exciter ring.
Check sensor setting.
5-12 front right
5-13 rear left
5-14 front left
5-15 rear right
sensor or wiring has intermittent fault
check wiring
6-12 to 6-15 same order
no output from sensor.
check sensor setting
4-12 to 4-15 same order
wiring to sensor broken or sensor resistance to high.
check wiring or fit new sensor
2-6 stop light switch
faulty switch or wiring. Fuse A5 blown or not fitted.
check pedal return or wiring/switch
2-7 continous supply to ecu with ignition off. faulty valve relay or wiring
check wiring and valve
2-8
no voltage to abs solenoid valves. faulty valve or relay.
check wiring.
3-0 to 3-9
open circuit in connection from ecu to solenoid valve in booster block or in ecu.
check wiring and connectors. renew ecu if wiring correct
4-0 to 4-9
short circuit in earth connection from ecu to solenoid valve in booster.
see above.
5-0 to 5-9 short circuit to 12volt in connection from ecu to solenoid valve in booster. possible earth fault.
see above
6-0 to 6-9 short circuit between two connections from ecu to solenoid valve in booster block.
check wiring valve and booster. replace ecu if no fault found.
There are more codes but not listed in haynes.
