Silverado 1500 2WD V6-4.3L (2007)
The IP harness may be in hard contact with the top rear edge (1) of the park brake assembly.
When releasing the park brake pedal with the park brake release lever/handle, the moving part (1) at the end of the park brake release cable may be
coming into hard contact with the IP harness.
Correction
If the symptoms match those listed above, or if a condition is found with one of the circuits running to C1 or C2 of the junction block or to the inline
IP-to-body connector (C202), then remove the front driver side door sill plate, driver side body hinge pillar trim panel, left IP outer trim cover and
perform the following steps:
Visually inspect the IP harness for damage at the park brake pedal assembly (refer to potential damage points in photos - at the side and rear of the park
brake assembly). Note that damage may be hidden from view (turned away from you, or covered by electrical tape).
Operate the park brake release lever. Is the moving part at the end of the park brake release cable coming into contact and damaging the IP harness?
Inspect the IP harness at this point. Note that the damage may be hidden from view (by electrical tape).
If damage is found, repair the wiring.
