teng Posted March 13, 2008 Share Posted March 13, 2008 My R33 S2 doesn't have lights on it's ECU either but at least mine doesn't have holes like the one you described. I haven't seen R33 Ecu having lights yet though. Most of the ECU i've seen are the concealed type.

Jmaac Posted March 16, 2008 Share Posted March 16, 2008 You have to switch the car to the right diagnostic mode by shorting some terminals on the diagnostic plug. Its all in the workshop manual That probably wont help with your stall issue, clean afm, aac etc. and go from there Link to comment https://www.sau.com.au/forums/topic/210274-diy-to-do-diagnostic-on-an-r33-s2/#findComment-3723213 Share on other sites More sharing options...
xr8eater Posted March 16, 2008 Author Share Posted March 16, 2008 i have cleaned the afm and aac is there any pics on how to do the shorting out prosess the work shop manual only has consult interface ways of doing it??????????

xr8eater Posted March 16, 2008 Author Share Posted March 16, 2008 (edited) ok after alot of messing about i will finaly give you guys a way to do a diagnostic on an S2 with no lights on the eccs first find the consult plug in the fuse bos next to the steering wheel as in pics next remove the plug end and turn your car to the on position dont start it get a paper clip and insert into only the holes shown for 2 seconds and remove your engine check light should start to flash a series of codes ECU Diagnostic Codes 11 Crankshaft position sensor 12 MAF sensor circuit (air flow meter) 13 Coolant temperature circuit 14 Vehicle speed sensor circuit 21 Ignition circuit 31 ECU (ouch!) 34 Knock sensor 43 Throttle position circuit 45 Injector leak 51 Ignition circuit 54 Auto signal to ECU 55 All OK Turn the ignition off to put the ECU back to normal and clear all faults. to check the o2 sensor follow the prompts above but dont tun the ignition off just start the car the check light will flash off for rich on for lean.

Jmaac Posted March 17, 2008 Share Posted March 17, 2008 Also your ecu will remember the fault codes for a approximately 50 starts, even if its been fixed since! must do reset Link to comment https://www.sau.com.au/forums/topic/210274-diy-to-do-diagnostic-on-an-r33-s2/#findComment-3725730 Share on other sites More sharing options...
xr8eater Posted March 17, 2008 Author Share Posted March 17, 2008 even with the standard reset disconecting the battery will not clear the diagnostic you have to perform the diagnostic to fully clear it Link to comment https://www.sau.com.au/forums/topic/210274-diy-to-do-diagnostic-on-an-r33-s2/#findComment-3726558 Share on other sites More sharing options...
thirtythree-II Posted March 26, 2008 Share Posted March 26, 2008 did the diagnostic test which worked perfrectly.... came upp with no. 12 afm prob. my consult plaug didnt have the black plug connected in it, is just opened.... also are r33 s1 ecu identical with their terminal connector numbers as a r33 s2. I need to check the continuity of terminal no. 26 & 27 which relate to the afm sensor wires.

Stormchaser Posted April 1, 2008 Share Posted April 1, 2008 Im having problems with the airbag light staying on. Would either the shorting the two wires in the diagnostic plug remove it or using the consult?
