Driving and Operating 6. Adjust the Trailer Gain to just below the point of trailer wheel lock-up, indicated by trailer wheel squeal or tire smoke when a trailer wheel locks. Trailer wheel lock-up may not occur if towing a heavily loaded trailer. In this case, adjust the Trailer Gain to the highest allowable setting for the towing condition. 7. Re-adjust Trailer Gain any time vehicle loading, trailer loading or road surface conditions change or if trailer wheel lock-up is noticed at any time while towing. Other ITBC-Related DIC Messages In addition to displaying TRAILER GAIN and TRAILER OUTPUT through the DIC, trailer connection and ITBC system status are displayed on the DIC. TRAILER CONNECTED: This message will be briefly displayed when a trailer with electric brakes is first connected to the vehicle. This message will automatically turn off in about 10 seconds. The driver can also acknowledge this message before it automatically turns off. CHECK TRAILER WIRING: This message will be displayed if: 1. The ITBC system first determines connection to a trailer with electric brakes and then the trailer harness becomes disconnected from the vehicle. If the disconnect occurs while the vehicle is stationary, this message will automatically turn off in about 30 seconds. This message will also turn off if the driver acknowledges this message or if the trailer harness is re-connected. 9-115 If the disconnect occurs while the vehicle is moving, this message will continue until the ignition is turned off. This message will also turn off if the driver acknowledges this message or if the trailer harness is re-connected. 2. There is an electrical fault in the wiring to the electric trailer brakes. This message will continue as long as there is an electrical fault in the trailer wiring. This message will also turn off if the driver acknowledges this message. To determine if the electrical fault is on the vehicle side or trailer side of the trailer wiring harness connection, do the following: 1. Disconnect the trailer wiring harness from the vehicle. 2. Turn the ignition off. 3. Wait 10 seconds, then turn the ignition back to RUN.

Adjust the Trailer Gain to just

below the point of trailer wheel

lock-up, indicated by trailer

wheel squeal or tire smoke

when a trailer wheel locks.

Trailer wheel lock-up may not

occur if towing a heavily loaded

trailer. In this case, adjust the

Trailer Gain to the highest

allowable setting for the towing

condition.

Re-adjust Trailer Gain any time

vehicle loading, trailer loading or

road surface conditions change

or if trailer wheel lock-up is

noticed at any time while towing.

Other ITBC-Related DIC Messages

In addition to displaying TRAILER

GAIN and TRAILER OUTPUT

through the DIC, trailer connection

and ITBC system status are

displayed on the DIC.

TRAILER CONNECTED: This

message will be briefly displayed

when a trailer with electric brakes is

first connected to the vehicle. This

message will automatically turn off

in about 10 seconds. The driver can

also acknowledge this message

before it automatically turns off.

CHECK TRAILER WIRING: This

message will be displayed if:

The ITBC system first

determines connection to a

trailer with electric brakes and

then the trailer harness becomes

disconnected from the vehicle.

If the disconnect occurs while

the vehicle is stationary, this

message will automatically turn

off in about 30 seconds. This

message will also turn off if

the driver acknowledges this

message or if the trailer harness

is re-connected.

If the disconnect occurs while

the vehicle is moving, this

message will continue until

the ignition is turned off. This

message will also turn off if

the driver acknowledges this

message or if the trailer harness

is re-connected.

There is an electrical fault in

the wiring to the electric trailer

brakes. This message will

continue as long as there is an

electrical fault in the trailer

wiring. This message will also

turn off if the driver

acknowledges this message.

To determine if the electrical fault is

on the vehicle side or trailer side of

the trailer wiring harness

connection, do the following:

Disconnect the trailer wiring

harness from the vehicle.

Turn the ignition off.

Wait 10 seconds, then turn the

ignition back to RUN.
