Trouble codes from ECU-Mark 1 85-89 Models

[mr2tim]

Since I only have an 89 Service Manual does any one know whether all Mark1 Trouble Codes are the same from 85-89?

What are the following? Do they relate to Mark1 mr2's?

TCCS-E
TCCS-L
TCCS-M

How do/can Mark 1 ECU's produce EFI Codes?

The early MK1 codes are different, here are the procedures and codes.
Check codes with the throttle closed, transmission in neutral, all accessories off, and engine at normal operating temperature.
Turn ignition to ON but do not start,
Short T - E1 on service connector,
The check engine light will flashing indicating the codes.
Normal code is 1 flash every 5 seconds or so.
Fault codes will read in ascending order, - code - 2.5 second pause - code - 2.5 second pause - code, etc. until all codes are read.

1 = Normal (No codes recorded)
2 = AFM signal (Open in VC, VS, VB, or E2 or short in EC)
3 = Ignition signal (no signal from igniter 4 times in a row)
4 = water temp sensor (fault in coolant temp. sensor circuit)
5 = O2 sensor (open in O2 sensor - lean signal only)
6 = RPM signal (No Ne, G signal within several seconds after start)
7 = TPS (circuit fault in TPS signal)
8 = Intake air temp sensor (fault in intake air temp sensor circuit)
9 = (There is no 9)
10 = Starter signal (no STA signal before engine reaches 800 RPM)
11 = Switch signal (AC switch on, TPS idle switch off, or AT shift in D during check)

This is for the early NA MK1s.

Thanks Bro, I get an occasional question on the 85's and 86's and wanted to get things straight, evidently starting in 87 and thru to 89 we get the double digit signals.

BTW I've got a 86 NA AT parts car out back I'd sure like to move, know anybody interested in the bits and pieces?

I inventoried my garage after 19 years of racing and street driving, whatta think of my collection?
