Changan CS55 PLUS: Replacement fuse of the same specification blows immediately; investigate the circuit first

Symptoms

• A new fuse immediately blows again after replacement with one of the same rating. ^[1]

Possible causes

• The source requires identifying and eliminating the cause of the blown fuse before replacement; this passage does not pinpoint the specific component causing repeated fuse failure and does not infer damage to the controller, wiring harness or electrical device. ^[1]

Checks

• Follow the source instructions to switch off the ignition and electrical equipment, and check the fuse rating against the circuit diagram for the actual vehicle; if a new fuse of the same specification blows immediately, stop further attempts and refer the vehicle to a qualified technician for diagnosis. ^[1]

What to do

• Identify and eliminate the circuit fault first, then address the fuse using the original rating; high-current fuses and relays must be handled by a qualified technician. Do not mask the cause by repeatedly replacing fuses. ^[1]
