(PIR) (Canada Only).
Preliminary Checks: Conduct a thorough visual
inspection. Go to GlobalConnect/IVH and review
the service history of the vehicle. Detect unusual
sounds or odors. Record the diagnostic trouble
code (DTC) information in order to achieve an
effective repair.
Perform the Diagnostic System Check- Vehicle.
This will verify the proper operation of the system.
This will also lead the technician in an organized
approach and identify what category of diagnostic
to perform.
Check for related Bulletins, Recalls and
Preliminary Information (PI).
Review the following diagnostic categories:
6.1. Current DTC: Follow the designated DTC
diagnostic in order to make an effective
repair. Refer to Diagnostic Trouble Code
(DTC) List - Vehicle.
6.2. Symptom - No DTC: Select the appropriate
symptom diagnostic. Follow the diagnostic
steps or suggestions in order to complete the
repair. Refer to Symptoms - Vehicle.
6.3. No published diagnostics: Analyze the
concern. Develop a plan for the diagnostics.
The service manual schematics will display
system power, ground, input, and output
circuits. You can also identify splices and
other areas where multiple circuits are tied
together. Look at component locations to see
if components, connectors or harnesses may
be exposed to extreme temperature,
moisture, or corrosives such as road salt,

Page 5

battery acid, oil or other fluids. Utilize the
system description and operation and system
circuit description.
6.4. Intermittent/History DTC: An intermittent
condition is one that does not occur
continuously, may be difficult to duplicate, and
will only occur when certain conditions are
met. Generally, an intermittent is caused by
faulty electrical connections and wiring,
malfunctioning components, electromagnetic
interference (EMI), driving conditions, or
aftermarket equipment. The following
approaches and tools may prove to be
beneficial in locating and repairing an
intermittent condition or a History DTC.
6.4.1. Combining the technicians
knowledge and skill with the available
service information.
6.4.2. Evaluate the symptoms and
conditions described by the customer
on the Customer Concern Verification
Sheets.
6.4.3. Follow the procedures in Testing for
Intermittent Conditions and Poor
Connections.
6.4.4. Use the available scan tool, digital
multi-meter, or J-42598 with data
capturing capabilities.
7. Isolate the root cause then repair and verify the
correction using the Repair Verification. Verifying
that the DTC or symptom has been corrected may
involve road testing the vehicle.
8. Re-examine the Concern: If a technician cannot
successfully find or isolate the concern, a
re-evaluation is necessary. Re-verify the concern.
The concern could be an intermittent or normal
condition.
