Step
1. Install a scan tool.
2. With the scan tool, bring up the Powertrain Control Module
6
data list and select Engine Speed.
Is the scan tool operating properly?
Using the J 38792-A, Electronic Vibration Analyzer (EVA) 2 is
the preferred method for gathering necessary vibration
frequency data.
If the J 38792-A is not available, the necessary vibration
frequency data will have to be obtained based on symptoms
7 observed during testing. Review "Symptoms - Vibration
Diagnosis and Correction" to become familiar with the possible
frequency ranges. Review Symptoms - Vibration Diagnosis
and Correction, as necessary throughout the remainder of
diagnostics.
Is the J 38792-A available for use?
Install the J 38792-A.
Is the J 38792-A operating properly?
8
Did the customer concern indicate that the vibration occurs
9
ONLY while the vehicle is standing still?
Did the customer concern indicate that the vibration occurs
10
ONLY during heavy acceleration at launch?
1. Install the J 38792-A sensor, if available, to the pinion area
of the drive axle. Route the sensor lead wire clear of
rotating parts and loosely secure the wire clear of moving
parts. If it is not possible to install the J 38792-A sensor, if
available, to the drive axle, install the sensor to an
exposed portion of the floor panel or seat track in the area
that the customer noted is most respondent to the
vibration.
2. Select a smooth, level road.
3. With the vehicle at a stand-still, apply the regular brake
and place the transmission in the lowest forward gear.
NOTE
Do not accelerate to the point of causing the drive
11
wheels to squeal, slip or hop - this would obscure
the results of the test.
4. Release the regular brakes and accelerate aggressively to
32 km/h (20 mph).
5. Observe the vehicle for disturbances that match the
customer's description and note the following conditions:
– The vibration frequency reading, if detected by the J
38792-A
– The feel and/or sound of the disturbance
6. If a reading could not be obtained by the J 38792-A, move
the J 38792-A sensor, if available, to another part that is
respondent to the vibration and repeat steps 3-5.
Were you able to duplicate the customer's concern?
12 Is the vehicle primary driveline configuration rear wheel drive?
Is the vehicle equipped with a solid drive axle?
