What are the causes of 4WD warning light malfunctions?
1 Answers
Because the 4WD system also requires wheel speed data to adjust the working state of the central multi-plate clutch. Here are the related explanations: Animal damage: Rats entering the engine compartment may chew through ABS sensor wires, causing the dashboard to simultaneously illuminate ABS, ESP, and 4WD warning lights. Since both ABS and ESP act on the braking system, they require wheel speed data from each wheel. Oxidized or loose connectors: In most cases, the 4WD warning light comes on due to oxidized or loose 4WD switching connectors. For driving safety, immediate inspection at a repair shop is recommended.
