AFFECTED VEHICLE RANGE
CONDITION SUMMARY:
Situation:
A Brake Booster Travel Sensor is now available as a serviceable part. On initial diagnosis with IDS, Diagnostic Trouble Code (DTC) B2736 - Pedal
Travel Sensor Circuit Failure may be stored in the Dynamic Stability Control Module (DSCM). This fault may be caused by a faulty brake booster
travel sensor.
Action:
In the event of a customer concern of the above, follow the Diagnostic Procedure outlined below and, if necessary, replace the Brake Booster Pedal
Travel Sensor.
PARTS
TOOLS
WARRANTY:
Normal warranty policy and procedures apply. warranty policy and procedures apply.
DIAGNOSTIC PROCEDURE
IDS DATA LOGGER TEST
IDS data logger can be used to monitor the real time movement of the sensor position when the brake pedal is pressed (via the brake pedal
travel offset-not corrected output signal). This is best measured with the scale set to 0 > 30 mm. Monitor the progression of movement when
the brake pedal is pressed. No movement or any erratic / notchy movement of the sensor output signal will confirm the fault.

1. Connect the Midtronics PSC-550 power supply to the vehicle battery.
NOTE:
IDS with latest IDS DVD Patch File is required.
2. Connect the IDS to the vehicle and begin a new diagnostic session by entering the correct VIN for the current vehicle.
3. Follow the IDS prompts to read the vehicle configuration.
4. Select 'No' when prompted 'Do you wish to read diagnostic trouble codes?'

VERIFY POWER SUPPLY TO PEDAL TRAVEL SENSOR
1. Switch ignition 'ON'.
2. Verify supply voltage is 4.7 - 5.3 volts between pedal travel sensor connector harness pins refer to the table shown above.
Page 278
3. If pedal travel sensor supply voltage is not within the specified voltage range, check for continuity, short to ground and short to power in the
harness between the pedal travel sensor and the DSC module at connector harness pins refer to the table shown above.
4. Repair wiring as necessary.
5. If pedal travel sensor supply voltage is still outside the limits, then the DSC module may be faulty and require replacement.
VERIFY PEDAL TRAVEL SENSOR SIGNAL WIRE INTEGRITY
1. Check for continuity, short to ground and short to power between the connector pins refer to the table shown above.
2. Repair wiring as necessary.
3. Connect all electrical connectors.
VERIFY SYSTEM REPAIRS
1. Clear DTCs.
2. Perform an ignition reset.
3. Start engine and verify DSC warning light / message has cleared.
4. Press the brake pedal hard several times.
^ If no DTCs return, the repair is complete.

Unable to Reduce Climate Control Outlet Temperature - Diagnostic Procedure
Page 279
AFFECTED VEHICLE RANGE:
S-TYPE (X200) VIN: L00600 - N91220
Model Year: 2000 - 2008
CONDITION SUMMARY:
Situation:
The outlet temperature of the climate control system may not be able to be lowered from either the driver or passenger face and side vents; there may
also be an extreme difference between the driver and passenger sides. This issue may be caused by a fault within the Dual Coolant Control Valve
(DCCV) or the Dual Automatic Temperature Control (DATC) or an electrical circuit fault.
Action:
In the event of a customer concern of the above, refer to the Diagnostic Procedure outlined below to assist in determining if the fault is electrical or
mechanical.
PARTS:
No parts necessary; diagnostic information only
TOOLS:
IDS with latest IDS DVD Patch File; software first available on IDS DVD112 Patch File 1 Midtronics PSC-550 Vehicle Power Supply
