Apply switch active then release switch active,
refer to electrical circuit diagrams and check
apply/release switch circuits
Check and install a new switch as required C1D00-64 Park brake apply switch
- Signal plausibility
failure
Connector fault - bent,
loose or corroded pin(s)
Harness fault - primary or
secondary apply circuit
Switch fault
Refer to the electrical circuit diagrams and test
parking brake primary and secondary apply circuits
Check and install a new switch as required C1D01-11
Park brake release
switch - Circuit short to
ground
Connector fault - bent,
loose or corroded pin(s)
Harness fault - short to
ground
Switch fault
Refer to the electrical circuit diagrams and test
park brake primary and secondary circuit for short
to ground
Check and install a new switch as required C1D01-15
Park brake release
switch - Circuit short to
battery or open
Connector fault - bent,
loose or corroded pin(s)
Harness fault - open circuit
Harness fault - short to
power
Switch fault
Refer to the electrical circuit diagrams and test
parking brake primary and secondary release
circuits for open circuits or short to power
Check and install a new switch as required C1D01-1C
Park brake release
switch - Voltage out of
range
Connector fault - bent,
loose or corroded pin(s)
Harness fault - low
resistance to ground
Switch fault
Refer to electrical circuit diagrams and test park
brake switch primary and secondary switch circuits
for low resistance to ground
Check and install a new switch as required C1D01-62
Park brake release
switch - Signal compare
failure
Connector fault - bent,
loose or corroded pin(s)
Harness fault
Switch fault
Release switch active then apply switch active.
Refer to electrical circuit diagrams and check
switch circuits for open circuits or shorts. Repair
circuit or replace switch as required C1D01-64
Park brake release
switch - Signal
plausibility failure
Connector fault - bent,
loose or corroded pin(s)
Harness fault
Switch fault
Primary and secondary release switch inputs
signals do not match. Check connectors for
damaged pins, Refer to electrical circuit diagrams
and check switch circuits for open circuits or
shorts. Repair circuit or replace switch as required B1142-64
Ignition Status 1 -
Signal plausibility
failure
The hard wired ignition
status signal does not
agree with CAN messages.
Ignition power supply is
detected open circuit when
ignition status is set to
'ON'
Refer to electrical circuit diagrams and check
parking brake module ignition power supply for
short to ground, open circuit U0001-87
High Speed CAN
communication bus -
Missing message
CAN Bus circuit fault
Power distribution fault
Refer to the electrical circuit diagrams and check
the power and ground connections to the module.
Using the manufacturer approved diagnostic
system, complete a CAN network integrity test.
Refer to the electrical circuit diagrams and check
the CAN network U0001-88
High speed CAN
communication Bus -
Bus off
CAN Bus circuit fault
Power distribution fault
Refer to the electrical circuit diagrams and check
the power and ground connections to the module.
Using the manufacturer approved diagnostic
system, complete a CAN network integrity test.
Refer to the electrical circuit diagrams and check
the CAN network U0100-00
Lost Communication
with ECM/PCM A - No
sub type information
Engine control module /
system fault
Wiring harness fault
Check the Engine Control Module for related DTCs
and refer to the relevant DTC index
Refer to the electrical circuit diagrams and check
the power and ground connections to the module.
