Introduction
When the ABS system detects a fault, it lights a lamp on the dashboard. This means the controller has detected an issue and is highlighting it for attention. In common with a lot of manufacturers, Suzuki expects you to return the vehicle to a dealer to get the problem diagnosed. Dealers subscribe to an expense proprietary code reader system to read the codes and it becomes an expensive process to find out what is wrong. However, International regulations make it mandatory that non-Suzuki aligned garages can also carry out diagnosis, therefore Suzuki provides a manual way of getting the error codes out of the controller.
This is achieved by shorting out pins on a small connector located behind the dashboard. It is on the drivers side (both for Right Hand Drive and Left Hand Drive) behind the steering wheel, on the side of the steering wheel nearest the door. Therefore on vehicles with the steering wheel on the proper side (RHD) it is behind the dashboard behind the drivers right hand when it is holding the steering wheel. If you are in one of those Jimnys with the steering wheel on the wrong side (a legacy of being invaded by Napoleon) then it is behind the dashboard behind the drivers left hand when it is holding the steering wheel.
It is a Blue colour connector with a PINK wire (with black stripe) and a Black wire and SIX connector positions but only two in use.
Reading codes
To read the codes:
- drive the vehicle at over 30mph for at least 1 minute.
- Stop, switch off ignition
- Using a piece of wire, short the two pins in the connector together
- Variation: Early models (G13BB)require you to remove the ABS Diode (pull it out) at this point
- Turn on the ignition
The ABS light will now flash a code to tell you the fault, the flashing repeats itself
The code is a two digit code so will flash the first digit, pause for 1 second and then flash the second digit, then after a 3 second delay it will repeat.
The codes are:
Code | Reason |
---|---|
12 | Normal |
15 | G sensor circuit fault |
16 | Stop lamp switch circuit fault |
21 or 22 | Righthand Front sensor fault |
25 or 26 | Lefthand Front sensor fault |
31 or 32 | Righthand Rear sensor fault |
35 or 36 | Lefthand Rear sensor fault |
41 | Right front Hold solenoid valve |
42 | Right front Release solenoid valve |
45 | Left front Hold solenoid valve |
46 | Left front Release solenoid valve |
55 | Rear Hold solenoid valve |
56 | Rear Release solenoid valve |
57 | Power source issue |
61 | ABS Pump motor circuit |
63 | ABS Solenoid valve circuit |
71 | ABS control module |
Clearing codes
To clear the codes:
- Switch off ignition
- Using a piece of wire, short the two pins in the connector together
- Turn on the ignition
- Pull and Remake the wire link at least 5 times within a 10 second period
- Turn off ignition and remove wire
If necessary repeat the Reading cod section above to confirm that the code is now "12" = normal.
