Help needed reading ALB code

[69XSN]

Hello again prime members. My car recently started displaying the ABS, TCS and brake malfunction lights. After my search I concluded that it's a wheel speed sensor. I performed the diagnostic code check. I am getting two blinks in five second intervals and a total of six from the ALB light. However since I'm to dumb to decipher the 91 service manual, I can't tell which sensor is at fault. I would do the resistance test but since the issue is intermittent I'm afraid it will be a waste of time. If anyone can tell me how to read the code I would greatly appreciate it.

Re:

Update. Ok after speaking to a couple people about my problem, it seems that the code is read by just the number of blinks. According to the manual, it would mean that I'm having a problem with my master cylinder reservoir cap or the parking brake. Parking brake switch checks out ok but I don't have a clue how to test the reservoir cap. Has anyone ever had a cap go bad or knows how to check it? I hate just throwing parts at the problem, since I would like to understand the car better and save money. Calling on Larry B or other knowledgeable prime members. Again any input or advice would be greatly appreciated.

I have never seen this code, but in the brake reservoir cap is a float system to warn you of low brake fluid. Is your brake reservoir low?

There are a pair of wires from the cap that connects to a pigtail on the chassis. Give it a look to see if the reservoir is fill. If it is full, and the wires look good, I would see if you can get someone close with an NSX and swap the cap.

HTH,
