Code No. 41, 42, 43, and 44: ABS Solenoid Valve inside Hydraulic Unit (Open Circuit or Short Circuit)
Code No. 52: Valve Relay Problem (Stays off)
Code No. 53: Motor Relay Problem (Stays off)
Code No. 55: Motor System (Seized Pump Motor)

CIRCUIT OPERATION

Power is continuously supplied to the ABS-ECU through fusible link number 3 to operate the solenoid valve and motor.

DIAGNOSIS CODE SET CONDITIONS

These codes are displayed if the power supply circuit of solenoid valve or motor is open or shorted.

TROUBLESHOOTING HINTS (THE MOST LIKELY CAUSES FOR THESE DIAGNOSIS CODES ARE TO SET ARE:)

Damaged wiring harness or connector

Malfunction of the hydraulic unit (integrated with ABS-ECU)

DIAGNOSIS

STEP 1. Measure the voltage at ABS-ECU connector B-03.

Disconnect ABS-ECU connector B-03 and measure at the harness side.

Measure the voltage between terminal 1 and earth, and 19 and earth.

OK: System voltage

Q: Is the check result normal?

YES: Erase the diagnosis code memory, and recheck if any diagnosis code sets. If diagnosis code No. 41, 42, 43, 44, 52, 53, or 55 set, replace the hydraulic unit (integrated with ABS-ECU). Then go to Step 3

. If diagnosis code No. 41, 42, 43, 44, 52, 53, or 55 is not output, an intermittent malfunction is suspected. Refer to GROUP 00, How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunction

.
NO: Go to Step 2

STEP 2. Check the harness wires between fusible link number 3 and ABS-ECU connector B-03 (terminals 1 and 19).

NOTE: After inspecting intermediate connector A-14, inspect the wire. If intermediate connector A-14 is damaged, repair or replace it. Then go to Step 3

Q: Is any of the harness wires between fusible link number 3 and ABS-ECU connector B-03 (terminal 1 and 19) damaged?

YES: Repair it and go to Step 3

.
NO: Go to Step 3

STEP 3. Check whether the diagnosis code is reset.

Q: Do diagnosis codes No. 41, 42, 43, 44, 52, 53 or 55 reset?

YES: Go to Step 1

.
NO: The procedure is complete.
