TRACTION CONTROL SYSTEM (TCL) DIAGNOSIS

TSB Revision

TRACTION CONTROL SYSTEM (TCL)

35C-19

STEP: 2. Check the TCL indicator light bulb.
(1) Remove the combination meter (Refer to GROUP 54A,

Combination Meter

P.54A-66

and

P.54A-68

.).

(2) Check the TCL indicator light bulb.

Q: Is the TCL indicator light bulb burned out?

YES : Replace the bulb and then go to Step 9.
NO : Go to Step 3.

STEP: 3. Check the combination meter for the continuity.
(1) Remove the combination meter.(Refer to GROUP 54A,

Combination Meter

P.54A-66

.)

(2) Remove the TCL indicator light bulb (Refer to GROUP 54A,

Combination Meter

P.54A-68

.). Then measure the

resistance between the bulb terminals.

(3) Install the TCL indicator light bulb to the combination meter,

and then measure the resistance between the connector C-
41 terminals 43 and 52. The resistance reading at this time
should be much the same as the resistance measured at
step (2).

Q: Are the two resistance values extremely different each

other?
YES : Replace the combination meter (printed circuit board)

and then go to Step 9.

NO (much the same) : Go to Step 4.

STEP 4. Check the combination meter power supply
circuit.
(1) Disconnect the combination meter connector C-41, and

check at the harness side.

(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between the terminal 52 and ground. It

should be approximately 12 volts (battery positive voltage).

Q: Is the voltage approximately 12 volts (battery positive

voltage)?
YES : Go to Step 5.
NO : Go to Step 7.

STEP 5. Check the connectors A-02, C-41, and C-94.
Refer to GROUP 00E, Harness Connector Inspection

P.00E-2

.

Q: Is any of the connectors damaged?

YES : Repair it and then go to Step 9.
NO : Go to Step 6.

STEP 6. Check the continuity between the combination
meter and the ABS-ECU.
Check the continuity between the combination meter connector
C-41 (terminal 43) and ABS-ECU connector A-02 (terminal 13).

Q: Is there the continuity between the combination meter

connector C-41 (terminal 43) and the ABS-ECU
connector A-02 (terminal 13)?
YES : Replace the hydraulic unit (integrated with ABS-ECU)

(Refer to GROUP 35B, Hydraulic Unit

P.35B-51

.) and

then go to Step 9.

NO : Repair the harness wire and then go to Step 9.

STEP 7. Check the connectors C-41, C-101, and C-104.
Refer to GROUP 00E, Harness Connector Inspection

P.00E-2

.

Q: Is any of the connectors damaged?

YES : Repair it and then go to Step 9.
NO : Go to Step 8.

STEP 8. Check the continuity between the ignition switch
(IG1) and the combination meter.
Check the continuity between the ignition switch (IG1) and the
combination meter connector C-41 (terminal 52).

Q: Is there any continuity (less than 2 ohms) between the

ignition switch (IG1) and combination meter connector
C-41 (terminal 52)?
YES : Replace the hydraulic unit (integrated with ABS-ECU)

(Refer to GROUP 35B, Hydraulic Unit

P.35B-51

.) and

then go to Step 9.

NO : Repair the harness wire and then go to Step 9.

STEP 9. Check symptoms.

Q: Does the TCL indicator light illuminate 3 seconds when

the ignition switch is turned to the "ON" position with
engine stopped or upon start-up?
YES : This diagnosis is complete.
NO : Return to Step 1.
