CONDITION
- The customer may report flickering of the dash insert lighting, of the A/C control panel lighting, or of the inside light. The condition occurs when the accelerator is pressed while the vehicle is in P or N, or when the vehicle is shifted down when moving downhill.
- Only vehicles with PR number 8GH may be affected.
TECHNICAL BACKGROUND
When high electricity consumers are switched off when the battery is fully charged, the energy generated by the alternator is sometimes too great for the power system to absorb. This may lead to briefly-increased voltage, causing the lights to flicker.
PRODUCTION SOLUTION
No change. This characteristic is caused by the alternator design and is a normal condition of the vehicle.
SERVICE
Repairs and parts replacements do not change the above characteristic. Explain to the customer that this characteristic is not a malfunction.
