TOW MODE SWITCH

Description

INFOID:0000000009885872

When tow mode switch is “ON”, tow mode switch signals are sent to TCM from combination meter by CAN

communication line.Then it`s a tow mode condition.

Diagnosis Procedure

INFOID:0000000009885873

1.

CHECK CAN COMMUNICATION LINE

Perform the self-diagnosis. Refer to 

TM-38, "CONSULT Function (TRANSMISSION)"

.

Is any malfunction in the CAN communication indicated in the results?

YES

>> Check CAN communication line. Refer to 

TM-48

.

NO

>> GO TO 2.

2.

CHECK POWER SOURCE

1. Turn ignition switch “ON”. (Do not start engine.)

2. Check the voltage between tow mode switch connector M67 ter-

minal 1 and ground.

OK or NG

OK

>> INSPECTION END

NG

>> GO TO 3.

3.

CHECK TOW MODE SWITCH

1. Turn ignition switch “OFF”.

2. Disconnect tow mode switch connector.

3. Check continuity between tow mode switch connector M67 ter-

minals 1 and 2.

OK or NG

OK

>> GO TO 4.

NG

>> Repair or replace tow mode switch.

4.

DETECT MALFUNCTIONING ITEM

Check the following items. If any items are damaged, repair or replace damaged parts.

• Harness for short or open between combination meter connector terminal 35 and tow mode switch connec-

tor terminal 1.

• Harness for short or open between tow mode switch connector terminal 2 and ground.
OK or NG

OK

>> GO TO 5.

NG

>> Repair or replace damaged parts.

5.

CHECK COMBINATION METER

Check the combination meter. Refer to 

TM-6, "Work Flow"

.

OK or NG

OK

>> INSPECTION END

NO

>> Repair or replace damaged parts.

Data are reference values.

NOTE:
Confirm that the pointer swings only momentarily because the output time is so short. If the inspection is done with an oscilloscope, it
should be observed that the power source voltage lasts for 3.5 to 10 ms.
