GC8/GF8 ABS Fault codes and how to retrieve them.
Reading ABS fault codes - JDMVIP Forums JDM Japanese Cars Import Used Auctions
Mine ('95 GF8) has the little black two pin plug under the dash. I grounded the white/blue wire to retrieve the codes. Code numbers are the same as in the link. Last edited by sir-revalot; 06-09-2015 at 12:58 AM. |

Almost thought these were ECU codes, had to look again!
(ECU codes here http://www.perth-wrx.com/vb/stock-ec...unit-only.html) Would be handy if the ABS thing above had pics too! |

I used this guide this morning to diagnose the ABS faults present since completing my six speed GC swap, and I’ve been able to determine the codes, but after a little bit of searching I’ve come up relatively empty with regards to what they necessarily mean and am hoping someone on here might have seen them before and know what they mean exactly.
Faults triggered: 26 - Abnormal ABS sensor signal Right Rear 51 - Abnormal valve relay 54 - Abnormal stop light switch Taking a stab that 26 means the rear right sensor is shot, but all I’ve done to the back end is swap out the hubs/knuckles/shafts to R180 from later STi, using the standard GC speed sensor. Wouldn’t have thought it would spontaneously shit itself sitting around doing nothing for a year. The other two faults (51 and 54) don’t show up much on the googles when I’ve searched for them. Any help would be appreciated.

I would hazard a guess that #54 may indicate the switch on your brake pedal is inoperative or disconnected in some way.
With #26 can you swap the left and right sensors to test if it's the sensor or a connection? Does #51 refer to the proportioning valve?

I think you’re right on all accounts Steve, but it turns out that it was more than just the three codes, but nearly every ABS fault under the sun presented itself due to a bad grounding, and potentially because the car had sat in pieces for so long. After resetting the codes the only one still present was 26, indicating dodgy sensor in the rear, and after getting under the car I realised I hadn’t torqued the bolt up, so the sensor was sitting a little loose and not reading correctly. After tightening it up and resetting the codes again, everything came up good.
EDIT: I might point out that my biggest worry with the ABS was that I went ahead and used the STi front knuckles, and upgraded to the later model speed sensors in the front, and that they may not play nicely with the GC ABS system. So to anyone doing this conversion, you don’t have to use your standard GC front knuckles and driveshafts, despite this seeming to be the norm according to the half dozen shops I’ve spoken to. If you put later model front knuckles and hubs in, with the driveshaft tone ring, as long as you get the correct speed sensor for the knuckle, then it would appear to read speed correctly.
