General Information - Diagnostic Trouble Code (DTC) Index DTC: Rear
Differential Control Module (RDCM)
Description and Operation

Rear Differential Control Module (RDCM)


CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not
guarantee confirmation of a fault, and may also cause additional faults in the vehicle being tested and/or the donor vehicle
NOTES:


If the control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the
warranty policy and procedures manual, or determine if any prior approval programme is in operation, prior to the installation
of a new module/component


Generic scan tools may not read the codes listed, or may read only 5-digit codes. Match the 5 digits from the scan tool to
the first 5 digits of the 7-digit code listed to identify the fault (the last 2 digits give extra information read by the
manufacturer-approved diagnostic system)


When performing voltage or resistance tests, always use a digital multimeter accurate to three decimal places and with a
current calibration certificate. When testing resistance, always take the resistance of the digital multimeter leads into account


Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests


Inspect connectors for signs of water ingress, and pins for damage and/or corrosion


If DTCs are recorded and, after performing the pinpoint tests, a fault is not present, an intermittent concern may be the
cause. Always check for loose connections and corroded terminals


If the rear differential control module, rear differential actuator or the rear differential are replaced, the on demand self
test (ODST) must be carried out to calibrate the components


Check DDW for open campaigns. Refer to the corresponding bulletins and SSMs which may be valid for the specific
customer complaint and carry out the recommendations as needed

The table below lists all diagnostic trouble codes (DTCs) that could be logged in the rear differential control module, for

Noise Conditions

Gear noise is typically a howling or whining due to gear damage or incorrect bearing preload. It can occur at various
speeds and driving conditions, or it can be continuous
Chuckle is a particular rattling noise that sounds like a stick against the spokes of a spinning bicycle wheel. It occurs
while decelerating from approximately 64 km/h (40 miles/h) and can usually be heard all the way to a stop. The
frequency varies with vehicle speed
Knock is very similar to chuckle, though it may be louder and occurs on acceleration or deceleration. The tear down will
disclose what has to be corrected
Check and rule out tires, exhaust and trim items before disassembling the transmission to diagnose and correct gear noise.

The noises described under Road Test usually have specific causes that can be diagnosed by observation as the unit is
disassembled. The initial clues are the type of noise heard on the road test and the driving conditions.

Vibration Conditions


wear. NOTE: New Constant Velocity (CV) joints should not be installed unless disassembly and inspection revealed unusual

Clicking, popping or grinding noises may be caused by the following:

Cut or damaged CV joint boots resulting in inadequate or contaminated lubricant in the outboard or inboard CV joint
bearing housings
Loose CV joint boot clamps
Another component contacting the rear drive half shaft
Worn, damaged or incorrectly installed wheel bearing, suspension or brake component
Vibration at highway speeds may be caused by the following:
Out-of-balance front or rear wheels
Out-of-round tires
Driveline imbalance
Driveline run-out (alignment)


NOTE: Rear drive half shafts are not balanced and are not likely to contribute to rotational vibration disturbance.
Shudder or vibration during acceleration (including from rest) may be caused by the following:
Driveline alignment
Excessively worn or damaged outboard or inboard CV joint bearing housing
Excessively high CV joint operating angles caused by incorrect ride height. Check ride height, verify correct spring rate
and check items under Inoperative Conditions
Excessively worn driveshaft components

Leakage Conditions

1. Inspect the CV joint boots for evidence of cracks, tears or splits.

2. Inspect the underbody for any indication of grease splatter in the vicinity of the rear drive half shaft, outboard and
inboard CV joint boot locations, which is an indication of CV joint boot or CV joint boot clamp damage.
3. Inspect the inboard CV joint bearing housing seal for leakage.

Inoperative Conditions

If a CV joint or rear drive half shaft pull-out occurs, check the following:

suspension components for correct location, damage or wear
bushings for wear
subframe for damage
bent or worn components
- Stabilizer bar link
- Left-hand rear suspension lower arm and bushing
- Right-hand rear suspension lower arm and bushing
- Rear wheel hub and rear drive half shaft

Road Test

A gear-driven unit will produce a certain amount of noise. Some noise is acceptable and may be audible at certain speeds or
under various driving conditions as on a newly paved blacktop road. The slight noise is in no way detrimental and must be
considered normal.

The road test and customer interview (if available) provide information needed to identify the condition and give direction to
the correct starting point for diagnosis.
1. Make notes throughout the diagnosis routine. Make sure to write down even the smallest piece of information, because

it may turn out to be the most important.

2. Do not touch anything until a road test and a thorough visual inspection of the vehicle have been carried out. Leave the
tire pressures and vehicle load just where they were when the condition was first observed. Adjusting tire pressures,
vehicle load or making other adjustments may reduce the conditions intensity to a point where it cannot be identified
clearly. It may also inject something new into the system, preventing correct diagnosis.

3. Make a visual inspection as part of the preliminary diagnosis routine, writing down anything that does not look right.
Note tire pressures, but do not adjust them yet. Note leaking fluids, loose nuts and bolts, or bright spots where
components may be rubbing against each other. Check the luggage compartment for unusual loads.
4. Road test the vehicle and define the condition by reproducing it several times during the road test.

5. Carry out the Road Test Quick Checks as soon as the condition is reproduced. This will identify the correct diagnostic
procedure. Carry out the Road Test Quick Checks more than once to verify they are providing a valid result. Remember,
the Road Test Quick Checks may not tell where the concern is, but they will tell where it is not.

Road Test Quick Checks

1. 24-80 km/h (15-50 miles/h): With light acceleration, a moaning noise is heard and possibly a vibration is felt in the
front floor pan. It is usually worse at a particular engine speed and at a particular throttle setting during acceleration at
that speed. It may also produce a moaning sound, depending on what component is causing it. Refer to Tip-In Moan in
the Symptom Chart.

2. Acceleration/deceleration: With slow acceleration and deceleration, a shake is sometimes noticed in the steering
wheel/column, seats, front floor pan, front door trim panel or front end sheet metal. It is a low frequency vibration
(around 9-15 cycles per second). It may or may not be increased by applying brakes lightly. Refer to Idle Boom/Shake
/Vibration in the Symptom Chart.

3. High speed: A vibration is felt in the front floor pan or seats with no visible shake, but with an accompanying sound or
rumble, buzz, hum, drone or booming noise. Coast with the clutch pedal depressed or shift control selector lever in
neutral and engine idling. If vibration is still evident, it may be related to wheels, tires, front brake discs, wheel hubs
or front wheel bearings. Refer to High Speed Shake in the Symptom Chart.

4. Engine rpm sensitive: A vibration is felt whenever the engine reaches a particular rpm. It will disappear in neutral
coasts. The vibration can be duplicated by operating the engine at the problem rpm while the vehicle is stationary. It
can be caused by any component, from the accessory drive belt to the torque converter which turns at engine speed
when the vehicle is stopped. Refer to High Speed Shake in the Symptom Chart.

5. Noise/vibration while turning: Clicking, popping, or grinding noises may be due to a worn, damaged, or incorrectly
installed front wheel bearing, rear drive half shaft or CV joint.

6. Noise/vibration that is road speed relative: This noise/vibration can be diagnosed independent of engine speed or gear
selected (engine speed varies but torque and road speed remain constant). The cause may be a rear drive
axle/differential whine.
Road Conditions

An experienced technician will always establish a route that will be used for all NVH diagnosis road tests. The road selected
should be reasonably smooth, level and free of undulations (unless a particular condition needs to be identified). A smooth
asphalt road that allows driving over a range of speeds is best. Gravel or bumpy roads are unsuitable because of the additional
road noise produced. Once the route is established and consistently used, the road noise variable is eliminated from the test
results.


NOTE: Some concerns may be apparent only on smooth asphalt roads.

If a customer complains of a noise or vibration on a particular road and only on a particular road, the source of the concern
may be the road surface. If possible, try to test the vehicle on the same type of road.

Vehicle Preparation

Carry out a thorough visual inspection of the vehicle before carrying out the road test. Note anything which is unusual. Do not
repair or adjust any condition until the road test is carried out, unless the vehicle is inoperative or the condition could pose a
hazard to the technician.
After verifying the condition has been corrected, make sure all components removed have been installed.

Lift Test

After a road test, it is sometimes useful to do a similar test on a lift.

When carrying out the high-speed shake diagnosis or engine accessory vibration diagnosis on a lift, observe the following
precautions:


WARNING: If only one drive wheel is allowed to rotate, speed must be limited to 55 km/h (35 miles/h) indicated on the
speedometer since actual wheel speed will be twice that indicated on the speedometer. Speed exceeding 55 km/h (35 miles/h)
or allowing the drive wheel to hang unsupported could result in tire disintegration, differential failure, constant velocity joint
