Pinpoint Test P: The Traction Control System Cannot Be Disabled - Vehicles Equipped With A 1.6L GTDI Engine

• For vehicles equipped with Intelligent Access (IA),
  • place 1 Intelligent Access (IA) key inside the vehicle and all other Intelligent Access (IA) keys at least 1 meter (3 feet) away from the vehicle.
  • press the start/stop button without pressing the brake pedal.
• For vehicles without Intelligent Access (IA), turn the ignition to the ON position.
• Monitor the message center.

Does the message center display MYKEY ACTIVE DRIVE SAFELY? 

• Yes  : The current Intelligent Access (IA) key or Integrated Keyhead Transmitter (IKT) is a restricted key and is functioning correctly.

  REPEAT the test using different Intelligent Access (IA) keys or Integrated Keyhead Transmitters (IKTs) until the message center does not display MYKEY ACTIVE DRIVE SAFELY.

  GO to P2 

• No  : GO to P2 

• Using the message center, verify the MyKey® traction control setting configuration. Refer to the Owner's Literature for information on configuring the MyKey® functions.

• Yes  : GO to P5 
• No  : REPAIR the circuit.

• Measure:

  Positive Lead	Measurement/Action	Negative Lead
  C135-34		C2400-6

Is the resistance less than 3 ohms? 

• Yes  : GO to P6 
• No  : REPAIR the circuit.

• Measure:

• Connect ABS  module C135  . Make sure the connector seats and latches correctly.
• Connect driver heated seat switch C2400  . Make sure the connector seats and latches correctly.
• Operate the system and determine if the concern is still present.

Is the concern still present? 

• Yes  : CHECK OASIS  for any applicable Technical Service Bulletins (TSBs). If a TSB  exists for this concern, DISCONTINUE this test and FOLLOW the TSB  instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new ABS  module and HCU  assembly.

  REFER to: HYDRAULIC CONTROL UNIT (HCU)  .

• No  : The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. ADDRESS the root cause of any connector or pin issues.
