Chery Tiggo. Manual — part 2
Disconnection of the Negative Battery Cable
• Before beginning any electrical work, turn the igni-
tion switch to LOCK, disconnect the negative bat-
tery cable and then wait two minutes to allow the
backup supply of the air bag diagnostic monitor unit
to deplete its stored power.
• Disconnecting the battery cable deletes the memo-
ries of the clock, audio and DTCs, etc. Therefore, it
is necessary to verify those memories before dis-
connecting the cable.

PROPER SERVICE PRACTICES
Removal of Parts
• While correcting a problem, also try to determine its
cause. Begin work only after first determining which
parts and subassemblies must be removed and dis-
assembled for replacement or repair. After removing
the part, plug all holes and ports to prevent foreign
material from entering.
Component Disassembly
• If the disassembly procedure is complex requiring
many parts to be disassembled, make sure that all
parts are disassembled in a way that will not affect
their performance or external appearance. Identify
each part so reassembly can be performed easily
and efficiently.
Inspection of Parts
• When removed, inspect each part for possible mal-
function, deformation, damage or other problems.

sembly of all parts. If removed, replace these parts
