DTC 55

DESCRIPTION
The ABS control module monitors the voltage of each terminal ("E23-13", "E23-26", "E23-12" and "E23-25") of the solenoid circuit constantly with the ignition switch turned ON. It sets this DTC when the terminal voltage does not become low/high for the ON/OFF command from the module to the solenoid or the voltage difference between solenoid circuit terminals exceeds the specified value with the solenoid turned OFF.

Steps 1-4:

INSPECTION
Check each step of the flow chart as described.
Step 1 - Check resistance of the solenoid and short-circuit to the ground in the hydraulic unit.
Step 2 - Check that the circuit between the solenoid and fail-safe relay is open.
Step 3 - Check that the circuit between the solenoid and ABS control module is shorted to the power.
Step 4 - Check that the circuit between the solenoid and ABS control module is open and shorted to the ground.
