1. Tour Mode Switch/Indicator Always On or Inoperative
|
|

Circuit/System Description
The tour mode switch and tour mode LED are combined into one
switch module. The body control module (BCM) monitors the status of
the tour mode switch. When the tour 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 tour 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 B097F 01 is stored in the BCM memory.
Conditions for Clearing the DTC
The BCM no longer detects a malfunction.

Circuit/System Verification
| 1. |
Ignition ON, observe the scan
tool Suspension System Mode parameter while pressing and releasing
the Tour Mode Switch. Verify the reading changes between Comfort
and Sport Mode. |
| ⇒ |
If the parameter does not change between the
specified values, go to circuit/system testing. |
| 2. |
Observe the tour mode LED
while pressing and releasing the Tour Mode Switch. The tour mode
LED should turn ON and OFF. |
| ⇒ |
If the LED does not change between the specified
values, go to circuit/system testing. |
Circuit/System Testing
Static Test
|
Note: Circuit/system
verification must be performed before circuit/system testing.
|
| 1. |
Ignition OFF, disconnect the
X5 harness connector at the K9 Body Control Module. |
| 2. |
Ignition ON, verify the sport
mode LED is OFF. |
| ⇒ |
If the sport mode LED does not turn OFF, test the
control circuit for a short to voltage. |
| 3. |
If all circuits test normal,
test or replace the S48C Multi-Function Switch 1 - Instrument Panel
Tour Mode. |
Dynamic Test
|
Note: Circuit/system
verification must be performed before circuit/system testing.
|
| 1. |
Ignition OFF, disconnect the
harness connector at the S48C Multi-Function Switch 1 - Instrument
Panel Tour Mode. |
| 2. |
Ignition OFF, test for less
than 5 Ω between the ground circuit terminal 1 and
ground. |
| ⇒ |
If more than the specified range, test the ground
circuit for an open/high resistance. |
| 3. |
Ignition OFF, test for more
than 11 V between the control circuit terminal 3 and ground.
|
| ⇒ |
If less than the specified range, test the control
circuit for short to ground. 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
Comfort and Sport Mode. |
| ⇒ |
If the parameter does not change between the
specified values, replace the K9 Body Control Module. |
| 6. |
Ignition ON, test for more
than 11 V between the 12V 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. |
If all circuits test normal,
test or replace the S48C Multi-Function Switch 1 - Instrument Panel
Tour Mode. |
Component Testing
Indicator Test
Install a 10 A fused jumper between the tour mode switch terminal 6
and 12 V. Install a jumper wire between the sport mode switch
terminal 1 and ground. The indicator LED should illuminate.
If the tour mode switch indicator does not illuminate, replace the
S48C Multi-Function Switch 1 - Instrument Panel Tour Mode.
Repair Instructions
Perform the
Diagnostic Repair Verification after completing the diagnostic
procedure.
