Solenoid Valve and Motor Power Supply Circuit

TRACTION CONTROL SYSTEM (TCL) DIAGNOSIS

TSB Revision

TRACTION CONTROL SYSTEM (TCL)

35C-9

CIRCUIT OPERATION
Power is continuously supplied to the ABS-ECU
through fusible link number 6 to operate the solenoid
valves and motor. The ABS-ECU supplies power to
the solenoids. If controls each solenoid by switching
the ground circuit ON or OFF, depending on driving
conditions.

TCL DTC SET CONDITIONS
These codes are displayed if the power supply circuit
of solenoid valve or motor is open or short.

TROUBLESHOOTING HINTS (The most likely
causes for these DTCs are to set are:)

•

Damaged wiring harness or connector

•

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

DIAGNOSIS

Required Special Tools:

•

MB991223: Harness Set

•

MB991502: Scan Tool (MUT-II)

•

MB991529: Diagnostic Trouble Code Check Harness

STEP 1. Check the solenoid valve or motor power supply
circuit at the ABS-ECU connector A-02.
(1) Disconnect the ABS-ECU connector A-02 and measure at

the harness side.

(2) Measure the voltages between terminal 18 and ground, and

17 and ground.

Q: Are the voltages approximately 12 volts (battery

positive voltage)?
YES : Replace the hydraulic unit (integrated with ABS-ECU)

(Refer to GROUP 35B, Hydraulic Unit

P.35B-51

.).

Then go to Step 3.

NO : Go to Step 2.

STEP 2. Check the harness wire between the fusible link
number 6 and the ABS-ECU connector A-02.
NOTE: After inspecting the intermediate connector C-05,
inspect the wires. If the intermediate connector C-05 is
damaged, repair or replace it. Refer to GROUP 00E, Harness
Connector Inspection

P.00E-2

. If the connector has been

repaired or replaced, go to Step 3.

Q: Is any of the harness wires between the fusible link

number 6 and the ABS-ECU connector A-02 damaged?
YES : Repair it and then go to Step 3.
NO : Go to Step 3.

STEP 3. Check the diagnostic trouble codes.

Q: Does any of the diagnostic trouble codes 31, 32, 33, 34,

41, 42, 43, 44, 45, 46, 47, 48, 51, or 53 reset?
YES : Return to Step 1.
NO : This diagnosis is complete.
