Slip Indicator Light Remains ON

DESCRIPTION

The skid control ECU is connected to the combination meter via CAN and multiplex communications.
The SLIP indicator blinks during VSC and/or TRC operation.
When the system fails, the SLIP indicator comes on to warn the driver (Click here).
The SLIP indicator comes on when traction control is terminated by pressing the traction OFF switch.

INSPECTION PROCEDURE

NOTICE:

When replacing the brake actuator assembly, perform zero point calibration (Click here).

HINT:

The SLIP indicator light comes on when the traction OFF switch is ON.

1. CHECK CAN COMMUNICATION SYSTEM

1. Check if the CAN communication system DTC is output (Click here for LHD, or Click here for RHD).
   

   Result:

   Condition	Proceed to
   DTC is not output	A
   DTC is output	B

B	INSPECT CAN COMMUNICATION SYSTEM

A

2. CHECK MULTIPLEX COMMUNICATION SYSTEM

1. Check if the multiplex communication system DTC is output (Click here).
   

   Result:

   Condition	Proceed to
   DTC is not output	A
   DTC is output	B

B	INSPECT MULTIPLEX COMMUNICATION SYSTEM

A

3. CHECK IF SKID CONTROL ECU CONNECTOR IS SECURELY CONNECTED

1. Check if the skid control ECU connector is securely connected.

   OK:

   The connector should be securely connected.
   

NG	CONNECT CONNECTOR TO ECU CORRECTLY

OK

4. CHECK BATTERY

1. Check the battery voltage.

   Standard voltage:

   11 to 14 V
   

NG	CHECK AND REPLACE CHARGING SYSTEM OR BATTERY

OK

5. INSPECT TRACTION OFF SWITCH

1. Disconnect the traction OFF switch connector.

2. Measure the resistance according to the value(s) in the table below.

   Standard resistance:

   Tester Connection	Condition	Specified Condition
   3 - 4	Switch is pressed	Below 1 Ω
   3 - 4	Switch is not pressed	10 kΩ or higher

NG	REPLACE TRACTION OFF SWITCH

OK

6. INSPECT TRACTION OFF SWITCH (GROUND TERMINAL)

1. Measure the resistance according to the value(s) in the table below.

   Standard resistance:

   Tester Connection	Condition	Specified Condition
   J37-4 - Body ground	Always	Below 1 Ω

NG	REPAIR OR REPLACE HARNESS OR CONNECTOR (GROUND CIRCUIT)

OK

7. CHECK HARNESS AND CONNECTOR (SKID CONTROL ECU - TRACTION OFF SWITCH)

1. Disconnect the skid control ECU connector.

2. Measure the resistance according to the value(s) in the table below.

   Standard resistance:

   Tester Connection	Condition	Specified Condition
   A14-43 (CSW) - J37-3	Always	Below 1 Ω
   A14-43 (CSW) - Body ground	Always	10 kΩ or higher

NG	REPAIR OR REPLACE HARNESS OR CONNECTOR

OK

8. INSPECT COMBINATION METER ASSEMBLY

1. Reconnect the skid control ECU connector and the traction OFF switch connector.

2. Perform Active Test of the combination meter (meter CPU) using the intelligent tester (Click here).

   OK:

   The SLIP indicator light turns on or off in accordance with the intelligent tester.
   

   HINT:

   If troubleshooting has been carried out according to the Problem Symptoms Table, refer back to the table and proceed to the next step before replacing the part (Click here).

NG	REPLACE COMBINATION METER ASSEMBLY

OK
