Hi,

Terence here. I have a Toyota Celica 1.8 GTS year 2000.

Problem.

My ABS light on the gauge is always ON just after changing to a Side Mirrors with signal lights (turning left or right)

My ABS is not working since then and the ABS light is always ON.

After 2 months and when I brake moderately hard with no ABS, I have the growling sound from front suspension, like a growling steel being pulled or bent.

In other words, when I press the brake moderately hard, and when the tyre stops moving, I can feel the car throwing in front with the growling sound.

Questions
1) What is really happening? Anybody has the braking sound problem?
2) Has the inactive ABS cause damage to my stock suspension?
3) Could it be the company/person accidentally damage/remove the ABS fuse?

Any advice? The ABS light is still ON until now. Nobody seems to be able to fix this problem.

Previously, I do not have this problem.

I told the company/person to remove the side mirror signal connection, but the ABS lights remains there.

The person who change said he did not touch any ABS thing. He only fix the side mirrors and connect the side mirror signal lights.
to the fuse.

What I have tried
1) I when to the mechanic, and they tested the ABS sensor. Sensor is working.
2) They also read the ECU and try to delete the error saying ABS light on, but to no avail. Yes. ECU detected that the front right ABS is not working, but we tested the sensor it is working.
3) Removing the side mirror signal lights (turning left or right)

Previously no problem
I clearly remember that once the company/person who change the 2 side mirror with signal lights, the ABS light is ON.

Can anybody help? Do reply.

Have a nice day

I can't see a connection to changing out mirrors and ABS........

check your electrical system, maybe you wired something incorrectly causing the gauge cluster to malfunction.

Hi Burn1ing,

Thanks for your reply.

Yes, tomorrow I will check that immediately.

But clearly the ABS is not working

I am getting groaning noise from the car at dead stop.
In other words, when I press the brake pedal hard and the car dead stop, the groaning noise from the suspension or axle occur when the body roll forward a bit. What is really happening?

Could it be that the ABS is suppose to stop the FORCE and when it is not working, the problem occured?

2) They also read the ECU and try to delete the error saying ABS light on, but to no avail. Yes. ECU detected that the front right ABS is not working, but we tested the sensor it is working.

If the sensor is good its the wiring between the sensor and the ecm or small chance its the ecm.Usually a visual look of the wires will show the problem ,if not ohms test.
edit: the sensor needs to be tested with a lab scope

1)the car comes with an abs module, check your fuses for ABS. if they are good, find the ABS module in the car and have it inspected. 2) Jack up your car and inspect it with a flashlight, look for anything out of the ordinary. 3)check your brakes and the ABS lines.

if there are no problems with the above mentioned:

Check axles, Front suspension, ECU

of course you have to be somewhat mechanically inclined to know what to look for.

Sounds like the ABS is firing when it shouldn't. there is a procedure to read the ABS code by shorting two points on the OBD II connector & the ABS dash light will flash the problem code.

Check the sticky on how to read CEL codes... the one that's up there is for Euro/Jap version... so the instructions will cause the ABS codes to be read out instead... or check the manual here in the Tech section.

Hmmm if the ABS is firing when it should not chances are somone has violated one or moee of the wheelspeed sensor circuits and the system is seeing false signals.

Maybe this will help.

To read this... the number following the /xx = the flash sequence of the ABS Warning Light when you short Ts (14), Tc (13) & CG (4) of the OBDII connector as described, the DI refers to the Diagnostic page # in the manual, following the Cxxxx/xx is the detection item, the bulleted items are the trouble areas.

From the Manual:

2. SPEED SENSOR SIGNAL
(a) In case of not using TOYOTA hand-held tester:
Check the speed sensor signal. '
(1) Turn the ignition switch OFF.
(2) Using SST, connect terminals Ts and CG of DLC3.
SST 09843-18040
(3) Start the engine.
(4) Check that the ABS warning light blinks.
HINT:
If the ABS warning light does not blink, inspect the ABS warning
light circuit (See page DI-314).
(5) Drive vehicle straight forward.
HINT:
Drive vehicle faster than 45 km/h (28 mph) for several seconds.
(6) Stop the vehicle.
(7) Using SST, connect terminals Tc and CG of DLC3.
SST 09843-18040
(8) Read the number of blinks of the ABS warning light.
:

If every sensor is normal, a normal code is output (A cycle
of 0.25 sec. ON and 0.25 sec. OFF is repeated).
If 2 or more malfunctions are indicated at the same time,
the lowest numbered code will be displayed 1st.
(9) After doing the check, disconnect the SST from terminals
Ts and CG, Tc and CG of DLC3, and turn
ignition switch OFF.
SST 09843-18040

Using SST 09843-18040, connect the terminals Tc and CG of the DLC3.

Did you do anything electrical with the car?

Any change in the electrical system could flash ABS.

I replaced the brake light 7443 with a very bright LED with 42 LEDs. It turned on the ABS light. Shorted the OBD TC upper pin 4 to Common ground lower pin 5, The ABS was flashing weird 4 4 4 1 . Damn. Could not figure out the problem.

So put back an incandescent 7443 brake bulb and problem solved. ABS light stops.


New LED (Light Emitting Diode) technology reduces power consumption from 40% to 80%.

Great replacement for tail light, turn signal light, stop light, brake light, parking light, backup light and so on
Since the nature of the item being offered might fit a large variety of different vehicle and functions, please measure your old bulb make sure this is the correct application type of bulb.

The other LEDs wok fine: But This was the bad LED.:

Compatible with: 7443 7440 992 992A 7441 7444 T20 W21W .

LED Type: 3528 SMD (3.5mm×2.8mm)
LED Q'ty: 42 LED (30 around & 12 forward)
LED colour: Red
Socket type: 7443 / 7440
Voltage: 12V only
Power: 2.2W
Color temperature: 620K
Lifespan: 60,000 hours
