DECREASE
Status ET703 becomes DECREASE when the cruise control/speed limiter button is
pressed. This button is on the steering wheel, on the left-hand side.
Refer to the airbag technical note for the vehicle for details on removal of the driver's
airbag and carrying out the checks in complete safety (see 88C, Airbag and
pretensioners).
If status ET703 does not change to DECREASE, check the status of the cruise control/
speed limiter +/- button and check the condition of its connector.
If the connector is faulty and if there is a repair method (see Technical Note 6015A,
Repairing electrical wiring, wiring: Precautions for repair), repair the connector(s);
otherwise replace the wiring.
If the connection or connections are faulty and there is a repair procedure (see
Technical Note 6015A, Electrical wiring repair, Wiring: Precautions for repair),
repair the wiring, otherwise replace it.
Measure the resistance of the following connections while pressing the "-" button
(on the button tracks):
●Connection code86G of component 331.
●Connection code 86M of component 331.
If the resistance is not approximately 100Ω, check the continuity of the button when the
button is in the rest position.
If there is continuity, replace the +/- control button.
If the connection or connections are faulty and there is a repair procedure (see
Technical Note 6015A, Electrical wiring repair, Wiring: Precautions for repair),
repair the wiring, otherwise replace it.
SUSPENDStatus ET703 becomes SUSPEND when the cruise control/speed limiter "0" button is
pressed. This button is located on the steering wheel, to the right.
Refer to the airbag technical note for the vehicle for details on removal of the driver's
airbag and carrying out the checks in complete safety (see 88C, Airbag and
pretensioners).
If status ET703 does not become SUSPEND, check the status of the cruise control/
speed limiter R/0 button and the condition of its connector.
If the connector is faulty and if there is a repair method (see Technical Note 6015A,
Repairing electrical wiring, Wiring: Precautions for repair), repair the wiring,
otherwise replace the wiring.
Measure the resistance of the following connections while pressing the 0 button
(on the button tracks):
●Connection code86G of component 331.
●Connection code 86M of component 331.
If the resistance is not approximately 0Ω, replace the R/0 control button.
If there is continuity, replace the R/0 control button.
If the connection or connections are faulty and there is a repair procedure
(seeTechnical Note 6015A, Electrical wiring repair, Wiring: Precautions for
repair), repair the wiring, otherwise replace it.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

RESUME
Status ET703 becomes RESUME when the cruise control/speed limiter "R" button is
pressed. This button is located on the steering wheel, to the right.
Refer to the airbag technical note for the vehicle for details on removal of the driver's
airbag and carrying out the checks in complete safety (see 88C, Airbag and
pretensioners).
If status ET703 does not change to RESUME, check the status of the cruise control/

If the connector is faulty and if there is a repair method (see Technical Note 6015A,
Repairing electrical wiring, wiring: Precautions for repair), repair the connector(s);
otherwise replace the wiring.
If the connector is faulty and if there is a repair method (see Technical Note 6015A,
Repairing electrical wiring, Wiring: Precautions for repair), repair the wiring,
otherwise replace the wiring. Measure the resistance of the following connections
while pressing the R button (on the button tracks):
●Connection code86G of component 331.
●Connection code 86M of component 331.
If the resistance is not approximately 900 Ω, check the continuity of the connection
when the button is in the rest position.
If there is continuity, replace the R/0 control button.
If the connection or connections are faulty and there is a repair procedure
(seeTechnical Note 6015A, Electrical wiring repair, Wiring: Precautions for
repair), repair the wiring, otherwise replace the wiring.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.
