Circuit/System Description

The parking brake control module has an internal motor, apply actuator, release actuator, and temperature sensor. The parking brake control module

also contains the logic for applying and releasing the parking brake when commanded by the park brake control switch. When the parking brake

control module receives a signal from the switch the internal circuit board temperature is checked to verify it is within operating range before the

control module performs the requested operation.

Conditions for Running the DTC

Ignition OFF, ACCESSORY, or RUN mode.

Conditions for Setting the DTC

C0574 01, C0574 02

The parking brake control module detects a short to battery or a short to ground.

The ECM detects that both camshafts on either bank of the engine are mis-aligned with the crankshaft for greater than 1 s or for a cumulative time

of 4 s.

Action Taken When the DTC Sets

DTC P0008 and P0009 are type B DTCs.

Conditions for Clearing the DTC

DTC P0008 and P0009 are type B DTCs.

Diagnostic Aids

* Inspect the engine for any recent engine mechanical repairs. An incorrectly installed secondary timing chain can cause this DTC to set.

* A single failed camshaft actuator or actuator solenoid valve will not cause this DTC to set. This diagnostic algorithm is designed to detect an

alignment condition between a primary intermediate sprocket and the secondary timing chain, or the alignment between a primary

intermediate sprocket and the crankshaft. Either condition would cause the camshaft timing for both cams on one bank to be off an equal

number of degrees.

* The presence of DTCs P0008 and P0009 along with P0016, P0017, P0018, and P0019 indicates a possible condition with the primary timing

chain and the alignment between both intermediate sprockets and the crankshaft. Or, the crankshaft reluctor wheel has moved and is no

longer referenced to top dead center (TDC).

* Observe the desired and actual camshaft angle parameters with a scan tool before a DTC sets. This may help to isolate whether a condition is

specific to one camshaft, one bank, or caused by a condition with the primary crankshaft timing.

Circuit/System Verification

1. Clear the DTCs with a scan tool.

2. Allow the engine to reach the normal operating temperature.

3. Idle the engine for 10 minutes or until a DTC sets. Observe the DTC information with a scan tool, DTCs P0008 and P0009 should not set.

4. Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the

conditions that you observed from the Freeze Frame/Failure Records data.

Circuit/System Testing

1. Inspect the timing chains and tensioners for excessive wear or misalignment.

瀚慖f you find a condition with the timing chains or tensioners, repair as necessary.

2. Inspect the crankshaft reluctor wheel for being mis-positioned on the crankshaft.

瀚慖f you find a condition with the crankshaft, repair as necessary.

DTC Descriptor

DTC B3935 00

- Transponder Authentication Error

Circuit/System Description

When an ignition key is inserted into the ignition lock cylinder and the ignition mode is changed, the transponder embedded in the head of the key

is energized by the exciter coils surrounding the ignition lock cylinder. The energized transponder transmits a signal that contains its unique value,

which is received by the body control module (BCM). The BCM then compares this value to a value stored in memory. If the value is not correct,

the BCM disables engine start.

Conditions for Running the DTC

* Ignition is in the Accessory or Run position.

* A valid transponder value has been read.

Conditions for Setting the DTC

* The transponder value is valid and matches the value stored in the BCM memory.

* The transponder calculation of the challenge from the BCM does not match the BCM calculation.

Action Taken When the DTC Sets

* Vehicle starting will be disabled.

* The security indicator will illuminate. The driver information center will display a service message.

Conditions for Clearing the DTC

* A current DTC will be cleared when a valid transponder value has been read and authenticated.

* A history DTC will be cleared after 100 malfunction-free ignition cycles.

- Control Module Ignition On and Start Circuit Open

Diagnostic Fault Information

Circuit/System Description

The vehicle power mode master is the body control module (BCM). The ignition switch is a low current switch with multiple discrete circuits to the

BCM.

The power mode master will activate relays and other direct outputs of the power mode master as needed according to the calculated power mode.

Some relays controlled by the BCM are switched ignition voltage outputs that are pass through circuits within the BCM directly from the ignition

switch. If these circuits short to ground, the B+ circuit fuse to the ignition switch will open.

Conditions for Running the DTC

B1370 01

Ignition switch is in the Accessory position.

B1370 06

Ignition switch is in the Accessory, Run, or Crank positions.

Conditions for Setting the DTC

B1370 01

Ignition circuit is shorted to voltage.

B1370 06

* Ignition circuit is open.

* Ignition or run/crank relay circuit is shorted to ground.

* B+ circuit of the ignition run/crank relay is open or shorted to ground.

* Ignition run/crank relay control circuit open, including relay coil and ground.

Action Taken When the DTC Sets

The Instrument Cluster still functions except check engine light is always off.
