ABS Light staying on after SR swap

[smcgiv]

Hi there,

A few months ago I installed an S14 SR20det into my 98 240sx. Everything works fine however since the swap my ABS light has stayed on. The ABS unit itself was removed and then reinstalled in order to feed the wiring harness through the firewall. I have bled all four corners and unplugged then replugged the abs brain in the trunk and still the light will not go off. The wheel sensors are fine. I have also tried to clear the codes but still no luck. I have even brought it to two different performance shops and they can't figure it out.

Has anyone experienced this after performing a swap? Or have any possible solutions to this problem??

Thanks!

Try this out and see if it works.

ABS LIGHT RESET/DIAGNOSTIC PROCEDURE


When a problem occurs in the ABS, the warning lamp on the instrument panel comes on. To start the selfdiagnostic
results mode, ground the self-diagnostic (check) terminal located on Data Link Connector. The
location of the malfunction is indicated by the warning lamp flashing.

SELF-DIAGNOSIS PROCEDURE
1. Drive vehicle over 30 km/h (19 MPH) for at least one minute.
2. Turn ignition switch OFF.
3. Ground terminal 9 of Data Link Connector with a suitable harness.
4. Turn ignition switch ON while grounding terminal 9.
Do not depress brake pedal.
5. After 3.0 seconds, the warning lamp starts flashing to indicate
the malfunction code No. (See NOTE.)
6. Verify the location of the malfunction with the malfunction code
chart. Then make the necessary repairs following the diagnostic procedures.
7. After the malfunctions are repaired, erase the malfunction codes
stored in the control unit. See Below
8. Rerun the self-diagnostic results mode to verify that the malfunction
codes have been erased.
9. Disconnect the check terminal from the ground. The self-diagnostic
results mode is now complete.
10. Check warning lamp for deactivation after driving vehicle over 30
km/h (19 MPH) for at least one minute.
11. After making certain that warning lamp does not come on, test
the ABS in a safe area to verify that it functions properly.
NOTE:
The indication terminates after 5 minutes.
However, when the ignition switch is turned from OFF to ON, the
indication starts flashing again.
