mr2 turbo 1996 conversion abs problem

[goggins1234]

hi all I replaced my abs ring on the my rear passenger side drive shaft it's all lined up as it should be but let's say on a 5 mile journey I get approx. 3 single clicks on the brake pedal not 3 together though 1 click on 3 single times when coming to a halt could I have the abs pump wired up wrong as I can hear the abs pump engaging when it does this it's minimal now though
any advice would be gratefully appreciated
thanks in advance

How could the pump be wired incorrectly?

[goggins1234]

I don't know long shot really
there's no abs light on the dash and no error codes

[goggins1234]

Sorry Peter I meant re pinning at ecu end?

[goggins1234]

Before I replaced the abs ring it the same problem happened a lot more but still no light on the dash and no codes I've replaces the hub speed sensor and abs ring

[goggins1234]

Also would a fault in the abs system put the ecu in low boost mode?

[Peter Gidden]

I've only had the problem of ABS engaging at very low speeds once - on a GT4 - and it took me days to find the fault. IIRC, it was a sticky caliper.

[goggins1234]

ok sorry my mistake
I do have abs error codes 11, 34, 36
I think it means the left rear speed sensor is faulty but I replaced it
can someone please confirm is left rear driver or passenger side?

[Peter Gidden]

11 open circuit in solenoid relay circuit
34 rear left wheel speed sensor signal malfunction
36 open circuit in front right or rear left wheel speed sensor

If you've replaced it and still getting fault codes, then you still have a problem.

I thought you had a problem with the sensor ring? But you say you replaced a sensor too?

You can check for open circuit in sensor using instructions in BGB and an ohm meter.

We check waveform using a 'scope.

I replaced the rear passenger hub which had the speed sensor already fitted

is rear left passenger side??

Rear left is passenger side.

So you didn't mess with the ABS ring on the driveshaft?

Have ytou cleared the fault codes from the ECU and confirmed they have cleared?

[goggins1234]

I replaced the hub and sensor a while back didn't know about the error codes for the abs system back then so believed I still had the fault so yesterday went to my friends garage and replaced the abs ring on the end of the drive shaft passenger rear

I cleared the codes this evening took it for a short test drive still abs engaging when driving slow or coming to an halt
sometimes the pedal dosent click but I can here it engaging from under the frunk

[goggins1234]

since I replaced the abs ring its happening a lot less
the old abs ring was slightly damaged and worn down on the one side
this is why I replaced it believed this to be the problem

[Peter Gidden]

Well if those codes are there now, you have two faults to sort out.

Suggest you get a 'scope on the sensor wire plug and check you have a good waveform.

Then you need to look into the solenoid fault.

[goggins1234]

the codes are not present at the mo but only drove up and back down my street

11 is still present though

going to to take another look tomorrow as I think the tip of the sensor is dirty

[goggins1234]

just replaced the speed sensor for another one
there's an improvement but still present

error code 11 is still present no code 34 or 36
11 open circuit in solenoid relay circuit doe's this mean there's a break in the wires somewhere??

can someone please tell me where the abs solenoid relay is located?
thanks for all your help

[Peter Gidden]

Error code 11:

Open circuit in solenoid relay circuit

• Actuator inside wire harness
  Solenoid relay
  Wire harness in connector of solenoid relay circuit

Solenoid relay is with pump relay next to ABS actuator in frunk.

Diagnosis procedures are in BGB.
