Chery Tiggo (1st generation, T11): Connecting and Activating Cruise Control

Cruise control on a 2008 Tiggo T11 cannot be enabled by coding alone. The function works only if the engine control unit (SQR481F engine, electronic throttle) has the matching software and the cabin has the controls installed. The exact coding procedure for this model is not documented in publicly available service materials, so what follows is a general order of work. Check the details against the manufacturer's service information.

Difficulty: Hard Time: 3-6 hours (checking trim level, installing controls, setup) Steps: 10

Step by step

10 steps
  1. Determine whether your trim level has the function. Inspect the steering wheel and column stalks: on a factory-equipped version, the switch has buttons or a stalk with on/off, set and resume positions. If they are missing, the vehicle was built without cruise control.
  2. Connect the scan tool and read the engine control unit identification: software version and calibrations. Check whether the list of settings or adaptations includes a cruise control parameter. If there is no such parameter, the function cannot be enabled through software.
  3. If the unit does not have the function, you will need an engine control unit with suitable firmware from a trim level with cruise control. Flashing and pairing the unit are done with specialized equipment, so for this stage contact a Chery dealer or a shop that does ECU tuning and flashing.
  4. Disconnect the negative battery terminal and wait 5-10 minutes so the capacitors discharge and the airbag safety lockout engages.
  5. If the steering wheel has an airbag, remove the airbag module or clock spring (spiral cable) only with the battery disconnected and after the waiting time. If you have no experience working with SRS, it is better to leave this stage to a repair shop.
  6. Install the cruise control switch and route the harness from it to the engine control unit. Take the pinout, wire colors and connector pins from the wiring diagram for your trim level. Do not find pins by trial and error.
  7. Check the brake pedal (stop lamp) switch. Cruise control must disengage when the brake is pressed. For this, the unit needs the signal from the pedal switch over two independent circuits. This is important for safety, and the function depends on this signal. If the switch has a single contact group, replace it with a two-contact one.
  8. If the transmission is an automatic, the unit must receive a selector position signal. Check that cruise control does not engage when N or P is selected.
  9. Connect the battery, start the engine and check that the scan tool shows no fault codes. Then clear any codes that appeared after the work.
  10. Test operation on a flat road with a good surface and light traffic, at a speed not below the function's minimum (usually 40-50 km/h). Check engagement, set, +/-, and resume, and be sure to check that it disengages when you press the brake and the clutch (manual transmission).

Common mistakes and warnings

  • Cruise control operates the throttle and is tied into the brake system, so wiring mistakes are dangerous: the vehicle may fail to disengage the mode when braking
  • If you have no experience with wiring diagrams, SRS and ECU flashing, leave the work to a specialized shop
  • Do not use the function in heavy traffic, on slippery roads or on winding mountain roads
