E-5 When diagnosis codes "41 FR SOL. VALVE", "42 FL SOL. VALVE" or "43 VALVE DRIFT"
are displayed.
[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

In the resistance value for
the solenoid valve within
the range of the standard
values?
Standard value: 1.1 - 1.3 R

TSB Revision
solenoid coil wire is broken/short-circuited or the
harness is broken/short-circuited, and then these
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.
