[MR FOR NISMO RS MODELS]

NO-1 >> No request for I/M examination from the customer: Before returning the vehicle to the customer,

always erase unnecessary DTC in ECM and TCM ( With CONSULT: Refer to “How to Erase
DTC and 1st Trip DTC” in

EC-84, "CONSULT Function"

, Without CONSULT: Refer to “How to

Erase Self-diagnostic Results” in

EC-81, "On Board Diagnosis Function"

). If the completion of

SRT is needed, drive vehicle under the specific driving pattern. Refer to

EC-169, "SRT Set Driving

Pattern"

NO-2 >> I/M examination, requested from the customer: GO TO 13.

Diagnostic Work Sheet

INFOID:0000000012197714

DESCRIPTION

There are many operating conditions that lead to the malfunction of

engine components. A good grasp of such conditions can make trou-

bleshooting faster and more accurate.

In general, each customer feels differently about symptoms. It is

important to fully understand the symptoms or conditions for a cus-

tomer complaint.

Utilize a diagnostic worksheet like the WORKSHEET SAMPLE

below in order to organize all the information for troubleshooting.

Some conditions may cause the MIL to illuminate or blink, and DTC

to be detected. Examples:

• Vehicle ran out of fuel, which caused the engine to misfire.

• Fuel filler cap was left off or incorrectly screwed on, allowing fuel to

evaporate into the atmosphere.
