3. ZR1 ABS Code - Definition
1990 Service Manual:
(* = Requires Tech 1 Daignostic Tool)
12 - Diagnostic System Operational
21 - RF Wheel Speed Sensor Fault
22 - RF Toothed Wheel Frequency Error
25 - LF Wheel Speed Sensor Fault
26 - LF Toothed Wheel Frequency Error
31 - RR Wheel Speed Sensor Fault
32 - RR Toothed Wheel Frequency Error
35 - LR Wheel Speed Sensor Fault
36 - LR Toothed Wheel Frequency Error
41* - RF Solenoid Valve Fault
45* - LF Solenoid Valve Fault
55* - Rear Solenoid Valve Fault
61* - Pump Motor or Motor Relay Fault
63* - Solenoid Valve Relay Fault
71 - EBCM Fault
72 - Serial Data Link Fault
75 - Lateral Accelerometer Fault (Short to B+ or Ground, or Open Circuit)
76 - Lateral Accelerometer Fault (Signal Out of Range or Incorrect)
Clearing Codes
The fault codes in the EBCM's memory are erased in one of three ways:
1. Diagnostic Enable Line Procedure
2. Tech 1 "Clear Codes" Selection
3. Igniton Cycle Default
Whichever method is used, be sure to verify proper system operation and absence of codes when clearing procedure is completed.

4. ZR1 Ride Control (SRC) Codes.
12 = Start of sequence
13 = Left rear time out
14 = Right Front time out
21 = Left Front time out
22 = Right Rear time out
31 = Left Front out of position
32 = Right Front out of position
33 = Left Rear out of position
34 = Right Rear out of position
Out of position codes are triggered if the computer senses that the actuator has not found the end stop position on the shock. Remove actuator at the indicated shock. Turn the valve gear on the shock stops after about 3 / 4 of turn, then you have a bad actuator. If it spins around continuously then it is a bad shock
41 = Selective ride control switch short to voltage
42 = Selective ride control switch open contacts
You can have a code 42 if you leave the switch in between indented positions
43 = selective ride control switch circuit open.
23 = If you start the car more than 3 times and do not move the car this code will set. Drive 3-6 feet and the light will go out.
The ride control controller is located in the bin behind the drivers seat mounted with the ABS controller.

Good to fold up and leave in the glove box along with your tool.

-=Jeff=- · 09-30-2015

Nice list..

LT5Vette · 10-07-2015

FYI additional on SIR codes you may get a 13 that indicates no history codes in memory.
See post

Hoping that I don't need to deal with any codes, but looking forward to learning more about how the information is presented and what the codes mean.

First....which code are you trying to erase?
Are you sure you fixed the issue causing the Code?

Intermittent Codes are an issue. As I recall, Kevin has a problem erasing the INFL REST code. Often when Codes do not erase it simply means the issue has not been fixed. When you say you disconnected the battery I am assuming the Code then went away? For how long did it go away?

We are right back to intermittent Code 61 as experienced in this Vacuum/MAP sensor thead.

Code 61 Vacuum/MAP sensors

Code erasing is sensitive to timing of the pin grounding and it may require a repeat of the process several times.

Nice Video of the ALDL Code Reader.....

MuRCieLaGo · 11-11-2015

-Was trying to erase Code 61.
-Not sure that I fixed the issue.
-When I unplugged the battery, the Code went away. For how long, I don't know, I did two 10 miles ride since yesterday and the Code still did not show up again.
-Next time a SES light shows up, I'll try some more to erase that code with your Code Eraser. Maybe that 3 seconds was a 5 seconds and that's why it didn't work?

Thanks Dynomite!

Hi to all
-just vant to fix air bag light after repair ground on airb. sensor... zr1 94-
have 16 pin connector , which one is K to ground it? Clear code procedure is same like on the older cars ?

-done ground with 4th lower pin from left and got on dislpay c12 (1) and H64(9) what is that mean ?
tnx for replies ,Jano

Pin A is ground. the ALDL is a mirror image of this connector.

janozr1 · 12-26-2015

thank you but i have 16 pin plug...
