I was able to get the flash patterns of my "ABS" light thanks to "Spider77". I got the patterns but I need to know what the flash patterns represent. I called "Toyota" here where I live. They told me that "The only way they can get the code is only by plugging to the Diagnostic box under the hood" & it would cost me $120 for them just to grab the codes. I also tried "Celicatech" but the pdf files for the Celica like mine don't work. Only the 3S-GTE & AWD book they have there works.

If anyone can help me identify the code that would be great. I want to have the ABS light gone and my ABS system re-enabled if that's even possible. I know ABS work especially done by "Toyota" themselves would probably be in the 4-Digit range.

Here are the flash patterns for the ABS

F= single flash
p= pause
------------------------------------
FFF p F
FFF p FF
FFF p FFFFF
FFF p FFFFFF
FFF p FFFFFFF

^^^ Is my whole ABS system F**Ked? cause thats five codes...

Also is it normal that my airbag & cruise control light blinks at the same time constantly?

Thanks to anymore who helps me out.

Code 31
Malfunction of right front wheel speed sensor signal. Check
speed sensor, sensor rotor, wiring harness and connector. See SPEED
SENSOR DIAGNOSTICS under DIAGNOSIS & TESTING. See FRONT SPEED SENSORS
under COMPONENT TESTING.
Code 32
Malfunction of left front wheel speed sensor signal. Check
speed sensor, sensor rotor, wiring harness and connector. See SPEED
SENSOR DIAGNOSTICS under DIAGNOSIS & TESTING. See FRONT SPEED SENSORS
under COMPONENT TESTING.
Code 35
Open in left front or right rear wheel speed sensor circuit.
Check speed sensor, sensor rotor, wiring harness and connector. See
SPEED SENSOR DIAGNOSTICS under DIAGNOSIS & TESTING. See appropriate
speed sensor testing under COMPONENT TESTING.
Code 36
Open in right front or left rear wheel speed sensor circuit.
Check speed sensor, sensor rotor, wiring harness and connector. See
SPEED SENSOR DIAGNOSTICS under DIAGNOSIS & TESTING. See appropriate
speed sensor testing under COMPONENT TESTING.
Code 37
Rear speed sensor rotor malfunction. Check rear sensor
rotors.

From what I was reading about the airbag and cruise, if it flashes constantly then its good....sounds weird but thats what I read.

AS far as your ABS codes, that really is a lot...your going to need a wiring diagram (pre a schematic) to locate the common point. To me, an open would indicate a malfunction....But without a schematic, its really hard to tell what is tied into what....All I have is the wiring diagram, which looks like the ABS ECU.

But....
Front Speed Sensors
1) Remove front fender lining. Disconnect speed sensor
connector. Measure resistance between speed sensor terminals.
Resistance should be 600-1800 ohms.
2) Measure resistance between each sensor terminal and sensor
body. Resistance should be one megohm or more. If resistance is not as
specified, replace speed sensor.
Rear Speed Sensors
1) Remove rear seat cushion. Disconnect speed sensor
connector. Measure resistance between speed sensor terminals.
Resistance should be 800-2100 ohms.
2) Measure resistance between each sensor terminal and sensor
body. Resistance should be one megohm or more. If resistance is not as
specified, replace speed sensor.
Sensor Rotors
Visually inspect sensor rotor serrations for scratches,
cracks, missing teeth, or warping. Replace front drive shaft or rear
hub as necessary if rotor is damaged.
Thats what I got from CelicaTech....Check the connections first and make sure they are connected....but again, there are a large number of codes listed.
