General Information - Road/Roller Testing 
Description and Operation Published: 11-May-2011 
 
Road or roller testing may be carried out for various reasons and a procedure detailing pre-test checks, through engine starting 
and stopping, pre-driving checks, on-test checks to final checks on completion of the test is given in this section. 
 
Unless complete vehicle performance is being checked, the full road test procedure need not be carried out. Instead, those 
items particularly relevant to the system/s being checked can be extracted. 
 
Pre - Test Checks 
 
 
WARNING: If the brake system hydraulic fluid level is low, pedal travel is excessive or a hydraulic leak is found, do not 
attempt to road test the vehicle until the reason for the low fluid level, excessive pedal travel or hydraulic leak is found and 
rectified. 
 
It is suggested that pre-test checks, and functional tests of those systems/circuits which affect the safe and legal operations 
of the vehicle, such as brakes, lights and steering, should always be carried out before the road or roller test. 
 
Engine oil level 
Engine coolant level 
Tires, for correct pressure, compatible types and tread patterns, and wear within limits 
There is sufficient fuel in the tank to complete the test 
All around the engine, transmission and under the vehicle for oil, coolant, hydraulic and fuel leaks. Make a note of any 
apparent leaks and wipe off the surrounding areas to make it easier to identify the extent of the leak on completion of 
the test 
Starting the Engine 
 
 
CAUTION: On initial drive away from cold and within the first 1.5 km (1 mile), do not depress accelerator pedal beyond 
half travel until the vehicle has attained a minimum speed of 25 km/h (15 miles/h). Never operate at high engine speed or 
with the accelerator pedal at full travel whilst the engine is cold. 
With the ignition switched off, check: 
The parking brake is applied 
The transmission selector lever is in Park 
All instrument gauges (except fuel gauge) read zero 
 
With the ignition switched on, check: 
 
Ignition controlled warning lamps come on 
Engine coolant temperature gauge registers a reading compatible with the engine coolant temperature 
Fuel gauge registers a reading appropriate to the fuel level in the tank 
The operation of the parking brake and brake fluid level warning lamps 
 
On Road or Roller Test Check: 
 
 
CAUTION:  If road testing, check the brake operation  while still travelling at low speed before continuing with the test. If 
the brakes pull to one side, or appear to be otherwise faulty, do not continue with the road test until the fault has been found 
and rectified. 
Initial gear engagement is smooth 
Parking brake control operates smoothly and the parking brake releases quickly and completely 
Transmission takes up the drive smoothly, without judder 
The engine power output is satisfactory, full power is achieved, acceleration is smooth and pedal operation not stiff or 
heavy, and engine speed returns to idle correctly 
There is no excessive or abnormally colored smoke from the engine under normal driving, heavy load or overrun 
conditions 
Steering operation, including power steering, is smooth, accurate, not excessively heavy or with excessive free play or 
vibration. Does not pull to one side and self centres smoothly after cornering 
Speedometer, oil pressure warning lamp, coolant temperature gauge and tachometer register the correct readings or 
operate correctly 
Switches and controls operate smoothly and positively, warning lamps operate correctly and the direction indicator 
control self cancels when the steering is returned to the straight ahead position 
Heating and ventilation systems work correctly and effectively 
Brake operation and efficiency 
 
Brake Testing 
 
 
WARNING: When brake testing, avoid breathing the smoke or fumes from hot brakes, this may contain asbestos dust 
which is hazardous to health, see Health and Safety Precautions.  
Page 104 of 3039

Avoid brake testing on busy roads where it can cause inconvenience or danger to other road users. 
 
 
CAUTION: Brake testing which includes heavy brake applications should not be carried out with new brake pads/discs or 
linings/drums until the components have bedded-in. New brake friction components will not reach full efficiency until the 
bedding-in process is complete. 
 
Test the brakes at several speeds within the normal operating range using both light and heavy pedal pressure. Note any 
tendency to snatch, pull or drag, and any undue delay in application or release. 
Allow the vehicle to coast and note any tendency to pull to one side, or evidence that the brakes are binding. 
 
After stopping the vehicle (not immediately after a period of heavy braking), carefully check the brake temperature. A disc 
which feels hot, or appreciably hotter than the others, indicates that the brake is binding. 
After completion of the test, check for: 
Oil, coolant, hydraulic, air and fuel leaks 
Abnormal temperature of any moving components or assemblies, e.g. wheel hubs, transmission, axle etc., which might 
indicate over tightness or lack of lubrication

General Information - Diagnostic Trouble Code (DTC) Index DTC: Adaptive 
Damping Module (SUMB) 
Description and Operation 
 
Adaptive Damping Module (SUMB) 
 
 
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 diagnostic trouble codes 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 
 
 
Where an 'on demand self-test' is referred to, this can be accessed via the 'diagnostic trouble code monitor' tab on the 
manufacturers approved diagnostic system 
 
 
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 required 
 
he table below lists all diagnostic trouble codes (DTCs) that could be logged in the adaptive damping module, for additional 
diagnosis and testing information refer to the relevant diagnosis and testing section 
For additional information, refer to: Vehicle Dynamic Suspension (204-05 Vehicle Dynamic Suspension, Diagnosis and Testing).

Check for electrical continuity between the two connectors for 
each of the 3 terminals. Reconnect electrical connector at 
Control Module only. C: Check voltages at terminals within 
height sensor connector (sensor not connected), with respect 
to vehicle body. • Voltage to sensor ground connection should 
be ~0v • Voltage to sensor signal connection should be ~0v • 
Voltage to sensor supply connection should be ~5v All 
voltages should be within ± 0.15v. To check sensor operation 
on the vehicle: Check for water ingress around the height 
sensors, electrical connectors or shaft end. Check for 
excessive movement in the shaft in all directions. Raise 
vehicle (ideally on wheels-free ramp) until suspension on 
corner under investigation is at rebound to gain access to 
height sensor. Access may be improved by removing road 
wheel. Carefully disconnect the height sensor link from the 
upper suspension arm. Monitor the height sensor signal 
voltage output for the height sensor under investigation. 
Position the sensor arm so it is in the mid position and 
confirm that the voltage is around 2.5 volts. Move the sensor 
arm over the range ±40° around the mid position and confirm 
that the voltage changes smoothly between around 0.2 volts 
and 4.8 volts. If voltages are incorrect or do not change 
smoothly then replace sensor. NOTE: For angles of movement 
beyond ±40°, the sensor signal will clamp to a voltage of 
~0.15v or ~4.85v, depending on position of sensor lever. This 
is normal. When investigation is complete, refit height sensor 
link to upper arm. If any fixings to the height sensor body or 
mounting bracket were slackened or found to be loose or if a 
height sensor was changed, the vehicle ride height MUST be 
re-calibrated. Refer to the relevant section of the workshop 
manual for the calibration procedure C1A04-22

Inspect for damage or loose fixings. NOTE If any height 
sensor fixings were slackened or found to be loose or if a 
height sensor was changed, the vehicle ride height MUST be 
re-calibrated. Confirm that the correct height sensor part 
number is fitted, as specified in the service parts database. 
To check height sensor: Disconnect electrical connector to 
height sensor and inspect connecter pins & terminals for 
evidence of corrosion or water ingress. If no corrosion found,
