When diagnostic trouble codes "41 FL SOL. VALVE
[Explanation]
The ABS-ECU normally monitors the solenoid valve
drive circuit.
If no current flows in the solenoid even if the ECU
turns the solenoid ON or if it continues to flow even
when turned OFF, the ECU determines the solenoid
coil wire is broken/short-circuiited or the harness

is broken/short-circuited, and then these diagnostic
trouble codes are output. ABS-ECU controls the
solenoid valve current and if the current value of
the solenoid valves differs from each other in the
same mode, solenoid valve drift error is produced
and the ABS-ECU goes into the failsafe mode.

TSB Revision
The harness wire for the
solenoid valve circuit
whose resistance value is
outside the range of the
standard value is broken or
short circuited.
Repair harness.
Replace ABS-ECU.
