Electrical DTCs

The sport mode switch, tour mode switch, sport mode light emitting diode (LED) and tour mode LED are combined into one switch module. The body control module (BCM) monitors the sport mode switch and the tour mode switch. When either 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 or tour mode LED ON to notify the driver of the selected mode.

The ignition voltage is between 10.2-15.5 V.

BCM detects a ground signal for more than 2 min continuously.

DTC B0980 02 is a Type C DTC.

1. Verify no communication related DTC is set.

⇒	If any communication DTC is set, diagnose those first.

2. Ignition ON, observe the scan tool Suspension System Mode parameter while pressing and releasing one after the other S48C Multifunction Switch - Instrument Panel - Sport Mode and S48C Multifunction Switch - Instrument Panel - Tour Mode. Verify the reading changes between Comfort/Sport Mode/Normal/Hard.

⇒	If the parameter does not change between the specified values, go to circuit/system testing.

3. Observe the sport mode LED and the tour mode LED while pressing and releasing one after the other S48C Multifunction Switch - Sport Mode and S48C Multifunction Switch - Instrument Panel - Tour Mode. The sport mode LED and the tour mode LED should turn ON and OFF.

⇒	If the LED does not change between the specified values, refer to Sport Mode Switch/Indicator Always On or Inoperative.

Dynamic Test

Note: Circuit/system verification must be performed before circuit/system testing.

1. Ignition OFF, disconnect the S48C Multifunction Switch - Instrument Panel harness connector.
2. Ignition ON, observe the scan tool Suspension System Mode parameter while installing a 3 A fused jumper wire between the S48C Multifunction Switch - Instrument Panel terminal 5 and ground. Verify the reading changes between Sport Mode/Normal/Hard.

⇒	If the parameter does not change between the specified values, test the wiring harness for short to voltage or an open/high resistance. If the circuit test normal, replace the K9 Body Control Module (BCM).

3. Test the S48C Multifunction Switch - Instrument Panel ground circuit for an open/high resistance.
4. If the circuit test normal, replace the S48C Multifunction Switch - Instrument Panel.
