ABS Light on, tried code checking Options

[HaRv3sTeR]

So today i brought my car the a local mechanic to change a wheel bearing on the front passenger side. When i got home, i notice that the amber ABS light was staying on all the time. I called them and they told me they might accidentally knocked the sensor and need to check it out. When i realized how expensive such sensor is, i started searching on this forum to fix this the cheapest way. I started by unplugging the battery for 10-15min to reset the system (no luck), also the fuses/relays seems ok. I 'll try soon to do a code checking, volt/amp test on the sensor itself and check if the sensor if actually plugged in correctly.

Questions:

1-where is the sensor located? and how difficult it is to access it?
2-must i use the traditional diagnostic box to do the code checking or the ABS have it's own diagnostic box?
3-do you think it's fair to make the garage pay in case of sensor replacement?
4-do you know if our celica share the same sensor than other toyota models?..or the celica ST? (might help to find them)

thx for the help

this might help

94-95
ignition in the ON position,
bridge E1 & TC in the diagnostics box, just like checking codes, read the code from the ABS light


Code 11
Open in solenoid relay circuit. Check actuator wiring
harness, solenoid relay, solenoid relay wiring harness and solenoid
relay connector.

Code 12
Short in solenoid relay circuit. Check actuator wiring
harness, solenoid relay, solenoid relay wiring harness and solenoid
relay connector.

Code 13
Open in pump motor relay circuit. Check actuator wiring
harness, pump motor relay, pump motor relay wiring harness and pump
motor relay connector.

Code 14
Short in pump motor relay circuit. Check actuator wiring
harness, pump motor relay, pump motor relay wiring harness and pump
motor relay connector.

Code 21
Open or short circuit in solenoid for right front wheel.
Check actuator solenoid, wiring harness and connector.

Code 22
Open or short circuit in solenoid for left front wheel. Check
actuator solenoid, wiring harness and connector.

Code 23
Open or short circuit in solenoid for right rear wheel. Check
actuator solenoid, wiring harness and connector.

Code 24
Open or short circuit in solenoid for left rear wheel. Check
actuator solenoid, wiring harness and connector.

Code 31
Malfunction of right front wheel speed sensor signal. Check
speed sensor, sensor rotor, wiring harness and connector.

Code 32
Malfunction of left front wheel speed sensor signal. Check
speed sensor, sensor rotor, wiring harness and connector.

Code 33
Malfunction of right rear wheel speed sensor signal. Check
speed sensor, sensor rotor, wiring harness and connector.

Code 34
Malfunction of left rear wheel speed sensor signal. Check
speed sensor, sensor rotor, wiring harness, and connector.

Code 35
Open in left front or right rear wheel speed sensor circuit.
Check speed sensor, sensor rotor, wiring harness and connector.

Code 36
Open in right front or left rear wheel speed sensor circuit.
Check speed sensor, sensor rotor, wiring harness and connector.

Code 37
Rear speed sensor rotor malfunction. Check rear sensor
rotors.

Code 41
Battery voltage is less than 9.5 volts or more than 16.2
volts. Check battery and voltage regulator.

Code 51
Actuator pump motor is locked or pump motor circuit open.
Check pump motor, pump motor relay, vehicle battery, actuator wiring
harness, connectors, actuator pump motor circuit and actuator ground
bolt.

ABS Light Always On
Malfunction of ABS ECU. Inspect ABS ECU connector for proper
installation and undamaged terminals. Repair as necessary. If
connector is okay, temporarily substitute known good ABS ECU. Retest
system.

reset the codes..

i bet the wiring harness for the abs sensor got cut during the process (Code 21).. but we'll see.

shouldn't your local mechanic fix it, since they knocked the sensor?

thx for the help...i got one more question (check first post)

[HaRv3sTeR]

ok so i tried code check with both the E1/TC and E1/TE1 methods and it wasnt working both ways
first

E1/TC was making my green cruise light to flash continually while the E1/TE1 was making my Overdrive/Check engine lights flash continually

i tried to pull the short pin and then the E1/TC was giving me code 36 (by looking at ABS light) which is not helping very much.

curiously, i tried the engine code again (E1/TE1) but same results as short pin in (first try)..what does that mean: Overdrive/Check engine lights flash continually


im also thinking...maybe my mechanic installed a bearing that wasnt made for ABS...does such thing exist or it is the same bearing for all models?
