1. Sport Mode Switch/Indicator Always On or Inoperative
|
|
| |
Circuit/System Description
The sport mode switch and sport mode LED are combined into one
switch module. The body control module (BCM) monitors the status of
the sport mode switch. When the sport mode switch is pressed, the
BCM will request the suspension control module, transmission
control module (TCM) and engine control module (ECM) via serial
data to control the vehicle ride characteristic according to the
selected mode. The BCM will command the sport mode LED ON to notify
the driver of the selected mode.
Conditions for Running the DTC
The ignition is ON.
Conditions for Setting the DTC
The BCM detects a short to voltage on the indicator control
circuit.
Action Taken When the DTC Sets
DTC B097D 01 is stored in the BCM memory.
Conditions for Clearing the DTC
The BCM no longer detects a malfunction.

Circuit/System Verification
Observe the sport mode LED while pressing and releasing the
sport mode switch. The sport mode LED should turn ON and OFF.
Circuit/System Testing
| 1. |
Ignition OFF, disconnect the
harness connector at the Sport Mode Switch. |
| 2. |
Ignition OFF, test for less
than 5 Ω between the ground circuit terminal 1 and
ground. |
| ⇒ |
If greater than the specified range, test the
ground circuit for an open/high resistance. If the circuit tests
normal, replace the K9 Body Control Module. |
| 3. |
Ignition OFF, test for greater
than 11 V between the control circuit terminal 3 and ground.
|
| ⇒ |
If less than the specified range, test the signal
circuit for a short to ground or an open/high resistance. If the
circuit tests normal, replace the K9 Body Control Module. |
| 4. |
Install a 3 A fused jumper
wire to the control circuit terminal 3. |
| 5. |
Ignition ON, observe the scan
tool Suspension System Mode parameter while momentarily toggling
the fused jumper wire to ground. Verify the reading changes between
Normal and Hard. |
| ⇒ |
If the parameter does not change between the
specified values, replace the K9 Body Control Module. |
| 6. |
Ignition ON, test for greater
than 11 V between the 12 V reference circuit terminal 6 and
ground. |
| ⇒ |
If less than the specified range, test the signal
circuit for a short to ground or an open/high resistance. If the
circuit tests normal, replace the K9 Body Control Module. |
| 7. |
Ignition ON, sport mode switch
ON, test for less than 5 Ω between the control circuit
terminal 4 and ground. |
| ⇒ |
If greater than the specified range, test the
control circuit for an open/high resistance. If the circuit tests
normal, replace the K9 Body Control Module. |
| 8. |
If all circuits test normal,
test or replace the Sport Mode Switch. |
Component Testing
Static Test
| 1. |
Ignition OFF, disconnect the
Sport Mode Switch. |
| 2. |
Install a 10 A fused jumper
between the sport mode switch terminal 6 and 12 V. Install a jumper
wire between the sport mode switch terminal 4 and ground. The
indicator LED should illuminate. |
| ⇒ |
If the sport mode switch indicator does not
illuminate, replace the Sport Mode Switch. |
Repair Instructions
Perform the
Diagnostic Repair Verification after completing the diagnostic
procedure.
