Using SST, connect terminals TC and CG of the DLC3.
Turn the ignition switch to ON.
Observe the blinking pattern of the ABS warning and slip indicator lights in order to identify the DTC.
Tech Tips
If the ABS warning and slip indicator lights do not blink, inspect the TC and CG terminal circuit, and ABS warning and slip indicator light circuits.
Trouble Area | See procedure |
---|---|
TC and CG terminal circuit | |
ABS warning light circuit (Remains on) | |
ABS warning light circuit (Does not come on) | |
Slip indicator light circuit (Remains on) | |
Slip indicator light circuit (Does not come on) |
Count the number of blinks of the ABS warning and slip indicator lights.
Tech Tips
How to read DTCs:
Diagnostic trouble codes are represented by the number of blinks of a warning light. For example, code 21 would be shown by 2 blinks, a pause of 1.5 seconds, and then 1 blink.
If one code is detected:
The light repeats the same code after a pause of 4 seconds.
If multiple codes are detected:
The light outputs one code after another with a 2.5-second pause between each code.
When all codes have been output, there is a 4-second pause and then the light begins to output the codes again.
If more than 1 malfunction is detected at the same time, the lowest numbered code will be displayed first.
Check the details of the DTCs.
