NOTE:

The OBD II symbol is used on the circuit diagrams in
order to alert the technician that the circuit is essential
for proper OBD II emission control circuit operation. Any
circuit which fails and causes the malfunction indicator
lamp (MIL) to turn ON or causes emissions-related
component damage, is identified as an OBD II circuit.

Refer to Splicing Twisted or Shielded Cable .

IMPORTANT:

Twisted-pair wires provide an effective "shield" that helps
protect sensitive electronic components from electrical
interference. If the wires were covered with shielding,
install new shielding.
In order to prevent electrical interference from degrading
the performance of the connected components, you must
maintain the proper specification when making any
repairs to the twisted-pair wires shown :

The wires must be twisted a minimum of 9 turns per
31 cm (12 in) as measured anywhere along the
length of the wires.

The outside diameter of the twisted wires must not
exceed 6.0 mm (.25 in).
