Diagnosing ABS Faults is actually rather easy. Here is the basic procedure:
Tools
Small phillips screwdriver
Short peice of wire (6" or so if fine)
The procedure
Turn off the ignition before you start. Using the screwdriver, Take the side panel off the seat pedestal on the drivers side. There are 3-4 screws holding it on. You then need to pull the ABS warning Relay. Its a small square plug that has a green base and is the relay closest to the front of the seat.
Under the seat, you will find a small 4 pin connector near the back of the seat pedestal. It is blue. You want to connect the small wire between two holes. One hole has a black wire with a pink stripe. The other hole has a black wire. Bridge these two together and turn on the ignition. The ABS light will light, and then go out after 5 seconds. The ABS light will then start to blink in a pattern.
The pattern is: Pause, flash, pause, flash. This signifies the start of the pattern. Then there will be a 2.5 second pause and then a series of flashes which gives the first number of the code (2-6). This will be followed by a 2.5 second pause, and then a series of flashes for the second part of the number (0-15).
The sequence of start phase, first and second parts will continue until terminated by the operator, thus allowing the code obtained to be rechecked. To terminate the sequence disconnect the prewired plug from the diagnoostic plug. Wait for cycle to end before code will clear. NOTE: Termination will clear the memory of that particular fault. Do not terminate the sequence if unsure of the code number.
The memory is capable of storing more than one fault. To search the memory, reconnect the diagnostic plug, and await the next start phase. Repeat procedure until no further faults are stored in the memory. The memory is cleared when a long pause of 7.5 secs occurs after start phase.
The Codes
Fault Code Reason Remedy
2-12 - Front Right Too Large an air gap, or Check sensor setting and for damage to
2-13 - Rear Left sensor has been forced exciter ring. Check for rear bearing endfloat
2.14 - Front Left out by exciter ring
2-15 - Rear Right
5-12 Front Right Sensor or wiring has Check wiring
5-13 Rear Left intermittend fault
5.14 Front Left
5-15 Rear Right
6-12 Front Right No output from sensor Check sensor setting. Fit new sensor bush
6-13 Rear Left Sensor may have too large if necessary
6-14 Front Left an air gap
6-15 Rear Right
4-12 Front Right Wiring to sensor is broken Check wiring or fit new sensor
4-13 Rear Left or sensor resistance is too
4.14 Front Left high
4-15 Rear Right
2-6 Stop light switch Faulty switch or wiring. Check that the pedal returns fully to stop. Slowly
Fuse A5 blown or not fitted operate pedal by hand and check that 2 clicks are
heard from switch; stop lights come on at first click.
Otherwise check wiring and fuse
2-7 Continuous supply to ECU Check wiring and valve
with ignition off. Faulty valve
relay or wiring
2-8 No voltage to ABS solenoid Check wiring
valves. Faulty valve relay or
wiring
3-0 to 3-9 Open circuit in connection Check wiring and connectors. Renew ECU if
from ECU to solenoid valve wiring is correct
in booster, on in ECU
4-0 to 4-9 Short circuit to ground in Check wiring and connectors. Renew ECU if
connection from ECU to wiring is correct
solenoid valve in booster
5-0 to 5-9 Short circuit in connection to Check wiring and connectors. Renew ECU if
12 volt in connection from wiring is correct
ECU to solenoid valve in
booster. Possible ground fault
6-0 to 6-9 Short circuit between two Check wiring, connectors and booster. Renew
connections from ECU to ECU if no fault found.
