DTC 41

DTC 41: ABS Solenoid Valve inside Hydraulic Unit (Open circuit or short circuit)





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

ABS DTC SET CONDITIONS
These codes are displayed if the power supply circuit of solenoid valve or motor is open or shorted

TROUBLESHOOTING HINTS
- Damaged wiring harness or connector
- Malfunction of the hydraulic unit (integrated with ABS-ECU)

DIAGNOSIS





STEP: 1. Check the solenoid valve or motor power supply circuit at ABS-ECU connector A-02.
1. Disconnect connector A-02 and measure at the harness side.
2. Measure the voltage between terminal 18 and ground or 1 and ground.
Q:Is battery positive voltage approximately 12 volts?
YES:Replace the hydraulic unit (integrated with ABS-ECU) and then go to Step 3.
NO:Go to Step 2.











STEP: 2. Check the harness wire between fusible link number 3 and ABS-ECU connector A-02.

NOTE: After inspecting intermediate connector C-04, inspect the wires. If intermediate connector C-04 is damaged, repair or replace it. If the connector has been repaired or replaced, go to Step 3.

Q:Is any harness wire between fusible link number 3 and ABS-ECU connector A-02 damaged?
YES:Repair it then go to Step 3.
NO:Go to Step 3.
STEP: 3. Check the diagnostic trouble codes.
Q:Do the diagnostic trouble codes 41, 42, 43, 44, 45, 46, 47, 48, 51 or 53 reset?
YES:Go to Step 1.
NO:This diagnosis is complete.
