91PoloGreen Posted October 17, 2017 Share Posted October 17, 2017 A little help needed . I have been trying to decifer these diagnostic codes. Some match up to info on the site here, by dropping the zero, but some don't seem to be mentioned anywhere on site. So here are the codes I got: ECM = 0210, 0134, 0164, 2144, 0364 BCM = 4404, 4484, 5524 IPC, or "R" codes (Which I couldn't find the description for) = 0244, 0264, 0344 Any and all help will be appreciated.

Ronnie Posted October 17, 2017 Share Posted October 17, 2017 Welcome to the forum! You have an unusual amount of codes. The problem you are having with understanding the codes is I think you are writing them down wrong. The first three digits are the code number and the last digit is either a "c" (current) or an "h" (history). Example: ECM code 0210 is actually 021c. If you look that up in the ECM code chart you will see that it is the code for the Throttle Position Sensor that is current. The codes that are current are the ones you should be concerned with first. Most of the codes you list are history codes. Since you have so many codes you should reset the codes in diagnostics or disconnect the battery cable for a couple of minutes to reset the codes and then reconnect. After you do that drive the car and see what codes return. Report back here with the codes that return and we will try to help. Link to comment Share on other sites More sharing options...
jglawnyc Posted October 17, 2017 Share Posted October 17, 2017 Hey 91PoloGreen: I'm a 91 Polo Green too. Best Reatta color! How is your paint holding up? I definitely need a repaint soon. Good luck with your issues. Link to comment Share on other sites More sharing options...
91PoloGreen Posted October 18, 2017 Topic Author Share Posted October 18, 2017 Hey 91PoloGreen: I'm a 91 Polo Green too. Best Reatta color! How is your paint holding up? I definitely need a repaint soon. Good luck with your issues. Very cool! Well I have some clear coat issues in a few places but overall the paint looks like new. I think the car was kept indoors most of its life. Thanks, J Link to comment Share on other sites More sharing options...

Eclectic Posted November 18, 2017 Share Posted November 18, 2017 Very cool! Well I have some clear coat issues in a few places but overall the paint looks like new. I think the car was kept indoors most of its life. Thanks, J Hello, I also have a 1991, a coupe, but its blue with baby blue leather. Maybe we should keep in touch about codes and specific problems to the 91. Michael Johnson, Boulder Colorado Link to comment Share on other sites More sharing options...
Eclectic Posted November 18, 2017 Share Posted November 18, 2017 I have a lit Brakes! light but no sign of ABS lights, what does that indicate? Also FYI I recently repaired a intermittent but often recurring problem with complete pandemonium on the IPC. ELECTRICAL PROBLEM! flashing as the motor died, only to restart in a few minutes. I finally inspected all of the ground points behind the battery, and found one that was obviously not making good contact. That wire led towards the computer in the passenger footwell. After I polished those connections and put on some electrolyte grease, all of my problems went away... Now I am enjoying driving my "new" car again.

DAVES89 Posted November 19, 2017 Share Posted November 19, 2017 Maybe low brake fluid. Check the level with the key off and pump the brake pedal until it is "hard" then check the level. Link to comment Share on other sites More sharing options...
Eclectic Posted November 19, 2017 Share Posted November 19, 2017 The '91 Reatta doesn't have an accumulator, its a more standard pressure booster setup, and I had the fluid changed and refilled recently. The red BRAKE! light is always on, but the car is braking fine. Link to comment Share on other sites More sharing options...
Ronnie Posted November 19, 2017 Share Posted November 19, 2017 Check the emergency brake to make sure it completely released. It can turn on the red brake warning light. Also the fluid level sensor in the reservoir can turn it on. Link to comment Share on other sites More sharing options...

Eclectic Posted November 23, 2017 Share Posted November 23, 2017 Ronnie, you nailed it , the emergency brake was on a little. What is the procedure for removing the radio and cd player? Thanks in advance. The car is now running well. Link to comment Share on other sites More sharing options...

Thanks in advance. The car is now running well. Thanks for letting us know. The easy fixes are always the best ones. :) My '88 doesn't have the same radio/cd as your '91 so I can't help you with that. I'm sure another member will be along to give you advice soon.
