  Yes: GO to A2.
  
  No: GO to Pinpoint Test B.
A2: FUNCTION TEST 2
NOTE:
- An infra-red thermometer is used during this test.
- The steering wheel temperature should have increased by approximately 10°C after 5 minutes.
- Do not measure the steering wheel temperature at the seam in the in the leather; this is where the heater element starts and finishes and will produce inaccurate test results.
1. Set the steering wheel heater switch to off
2. Set the climate control to cool the vehicle interior for 5 minutes
3. Using an infra-red thermometer, measure and record the temperature of the steering wheel rim at six equidistant points
4. Set the steering wheel heater switch to on
5. Using an infra-red thermometer, monitor the temperature of the steering wheel rim at six equidistant points
  Has the temperature increased at any point on the steering wheel rim?
  
  Yes: GO to A3.
  
  No: GO to Pinpoint Test I.
A3: FUNCTION TEST 3
NOTE:
- An infra-red thermometer is used during this test.
- The steering wheel temperature should stabilize at 30°C to 43°C.
1. Using an infra-red thermometer, monitor the temperature of the steering wheel rim at six equidistant points
2. Wait for the temperature to stabilize
  Has the temperature stabilized within the specified range at all six points?
  
  Yes: Steering wheel heater operating normally
  
  No: GO to Pinpoint Test J.
