CAUTION: If a steering gear assembly is returned under warranty with leaking output shaft seals, but there is also 
damage to the steering gear boot/boots the steering gear warranty will be invalid. This is due to the steering gear output 
shaft seals being damaged due to foreign materials entering the steering gear boot and damaging the steering gear output 
shaft seals thereafter. 
 
3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to 
the next step. 
4. If the concern is not visually evident, verify the symptom and refer to the symptom chart. 
 
Symptom Charts 
 
 
WARNING: It is not possible to CHECK the torque of a patchlock bolt, if the torque is suspected to be low, the bolt must 
be REMOVED/DISCARDED and a new bolt MUST be INSTALLED and torque to the correct value. 
 
 
NOTE: If the module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the 
Warranty Policy and Procedures manual (section B1.2), or determine if any prior approval programme is in operation, prior to 
the installation of a new module/component. 
 
Fluid Leakage 
 
 
NOTE: Confirm the location of the fluid leak. CLEAN the area of the leak, inspect the area and confirm the exact position. 
Ensure the fluid is not from another system on the vehicle. 
 
Symptom Possible Causes Action

STEERING WHEEL HEATER 
 
On certain models the rim of the steering wheel contains a heater element. Operation of the heater is selected using the 
Touch Screen Display (TSD). 
 
The heater temperature is controlled by a heated steering wheel control module located within the steering wheel. Power for 
the heater element is supplied to the steering wheel via 2 contacts on the clockspring and a slip ring mounted on the steering 
wheel.
