Internal lights 3 (PWM5): Shortcut to U30 Not used
â–¶ How to fix
1. Check the harness
What you'll see
No driver-visible symptom recorded.
System reaction
Internal lights at max
Diagnostic depth
Detection
The demanded output for PWM4 (pin O1 A:24) is 0% but the PWM feedback is in range 1,1V to 1,3V. (< 0,9V is ok) 10 pendings for validation
Possible cause
1) The harness is shorted to U30 2) Internal shortcircuit to U30
