Problem Code 10: ABS control unit (front relay
circuit)
1. ABS Indicator Checking
• The ABS indicator blinks or comes on and
stays on when the ABS control unit has been
disrupted by an extremely powerful radio
wave (electromagnetic interference). This is
just a temporary symptom. Erase the prob-
lem code and the ABS control unit is normal
unless the symptom occurs again.
Turn the ignition switch to "ON" and check the
ABS indicator.
Is the indicator blinking?
NO – GO TO STEP 2.
YES – GO TO STEP 3.
2. ABS Indicator Function Inspection
Retrieve the problem code and erase it. Perform
the pre-start self-diagnosis and check the ABS
indicator.
Is the indicator blinking?
NO – Normal (temporary failure). Fine foreign
matter in modulator or the ABS control
unit has been disrupted by an extremely
powerful radio wave. Check the connec-
tor and wire harness for loose connec-
tion.
YES – GO TO STEP 3.
3. Check Problem Code
Retrieve the problem code and record the latest
problem code.
Is the problem code 10 or other?
CODE 10 – GO TO STEP 4.
OTHER THAN CODE 10 – Diagnose at the latest
problem code.
