HOW TO DIAGNOSE AND RESET ABS LIGHT & FAULT CODES (RRC)

I found this video very helpful on YouTube from  Rough Restos
Here is the video link:  How to diagnose and reset the ABS light & fault codes
Here are the fault codes for quick access:

 

2-12 Front Right Too large an air gap, or sensor has been forced out by exciter ring – try tapping sensor back into place
2-13 Rear Left  
2-14 Front Left  
2-15 Rear Right  

 

4-12 Front Right Wiring to sensor is broken or sensor resistance is too high. Inspect wiring at sensors.
4-13 Rear Left  
4-14 Front Left  
4-15 Rear Right  

 

5-12 Front Right Sensor wire has an intermittent fault – check connection(s).
5-13 Rear Left  
5-14 Front Left  
5-15 Rear Right  

 

6-12 Front Right no output from sensor. Sensor may have too large an air gap. Try tapping in sensor(s), check
6-13 Rear Left  
6-14 Front Left  
6-15 Rear Right  

 

2-6 Stop Light Switch Faulty switch or wiring. Replace brake light switch.
2-7   Continous supply to the ECU with the ignition off. Faulty valve relay or wiring.
2-8   No voltage to ABS Solenoid valves. Faulty valve relay or wiring.

 

3-0 to 3-9   Open circuit or connection from ECU to solenoid valve in booster, or in ECU.
4-0 to 4-9   Short circuit to earth from ECU to solenoid valve in booster.
5-0 to 5-9   Short circuit to 12 volts in connection from ECU to solenoid valve in booster. Possible earth fault.
6-0 to 6-9   Short circuit between two connections from ECU to solenoid valve in booster.
