Possible causes of fault
- 'Short circuit to B+' between 'PWM (Pulse Width Modulation) switch' and 'selector switch (in running gear control module)'
- 'Short circuit to ground' between 'PWM (Pulse Width Modulation) switch' and 'selector switch (in running gear control module)'
- 'Open circuit' between 'PWM (Pulse Width Modulation) switch' and 'selector switch (in running gear control module)'
