HANDLING PRECAUTION FOR CRUISE
CONTROL SYSTEM
1. Be careful as the vehicle speed increases when
driving downhill with the cruise control system
on.
2. Do not use the cruise control system where the
road conditions are as follows:
•
Heavy traffic
•
Steep downhill
•
Roads with sharp turns
•
Icy or snowy roads
•
Slippery roads
3. When towing, do not use the cruise control
system. The weight of the trailer may cause
problems with cruise control functions, cause a
decrease in control performance and lead to
accidents.
PROCEDURE FOR DTC CONFIRMATION:
Procedure to confirm DTC comprises of 2 types as
mentioned below:
1. Dynamic test (vehicle driving condition)
2. Static test (vehicle stationery condition)
Majority of the faults can be detected in static test.
But certain faults listed below need dynamic test to
confirm the DTC
List of DTC needs to be confirmed with Dynamic
test:
PROCEDURE FOR STATIC TEST:
1.Start the engine with vehicle in neutral condition.
2.Warm up the engine.
3.Raise the engine speed gradually till 2000eRPM
and maintain for 5 seconds.
4.For crank/cam signal related faults raise the
engine speed gradually till no load maximum
speed and foot off back to idle, only once.
5.Observe the cluster for CEL/MIL, if any.
6.Stop the engine.
7.Check the DTC.
PRECAUTIONS TO BE TAKEN FOR STATIC
TEST:
1.Ensure all safety aspects before starting the
engine.
2.Don’t remove radiator cap once engine is hot.
NOTE
Any intermittent fault issue which is electrical in
nature needs to be subjected to dynamic test for
DTC confirmation.
