General Repair Information
WARNING: This page is about a different car, the 2017 Chevrolet Spark. However, it is still accessible from the selected car via links, so may be relevant.
- When performing work where there is a danger of an electrical short circuit, disconnect the battery negative cable from the battery. For Crossland X and Grandland X, disconnect the battery positive cable, as the battery negative cable is not accessible for these vehicles. The following procedure must be observed to avoid injury to persons and damage to sensitive electrical components:
- The battery terminals must be covered so that accidental contact does not occur because the battery cable has gradually moved backwards. This also prevents accidental contact during assembly, e.g. with bright metal components or tools.
- If individual connection cables forming part of the battery connection have to be dismantled, always remove the battery negative cable from the battery terminal first so that all the power circuits on the vehicle are free from voltage. For Crossland X and Grandland X, disconnect the battery positive cable, as the battery negative cable is not accessible for these vehicles. Non-adherence to this ruling can lead to electronic components being damaged. Reconnection takes place in reverse order, the earth clip is the last to be connected to the battery.
- Never connect / disconnect control unit or miscellaneous electronic component wiring harness plugs with the ignition switched on to avoid damaging the control units.
- Never pull on cable when disconnecting wiring harness plugs. Carefully release locking mechanism at wiring harness plug.
- When cleaning and contact sprays are being used, the manufacturer's recommendations must be followed. Improper use can damage sensitive electrical and electronic components.
- When returning a unit containing a CD unit (such as radio, navigation control unit and CD changer), remove all CD's to avoid damage to the laser head or CD.
- To charge the battery, use a battery charger approved by service.
- When programming the control unit memory system, ensure that no persons are present in the interior - risk of injury!
- After completing repair operations, ensure that wiring harness connections and battery connections are correctly seated and that ground connections have been made correctly. Defective electrical connections cause functional problems and destroy control units.
- Wiring harnesses and wiring troughs which are released or removed during repair work must be tightened in their original positions using genuine aftersales parts (cable ties, clips, wiring trough brackets, etc.).
- It is essential to ensure that retrofitted components must not be installed in the trigger path of the pyrotechnic restraint systems or airbags.
- Disconnecting the ground cable from the battery automatically erases the contents of certain electronic system memories (e.g. electric window winder, time and date). After reconnecting the ground cable to the battery, these volatile memories must be reprogrammed and audio equipment decoded.
- At certain vehicles equipped with ESP it is necessary to calibrate the steering angle sensor after disconnection of the battery negative cable. Refer to the corresponding service instructions.
- Active safety features, like e.g. lane keep assist, may cause unintended activity while vehicle is lifted or at the hoist with Ignition On/Vehicle in Service Mode. Make sure to de-activate all pro-active safety features and/or turn the ignition/vehicle Off before lifting the vehicle. If that is not possible because e.g. a measurement needs to be performed below the vehicle for diagnostic purpose, stay clear of the controlled components, like e.g. front wheels and the steering wheel for lane keep assist feature.
- While working below the vehicle with Ignition On/Vehicle in Service Mode, ensure that no hydraulic, fuel, pneumatic or other pipes and hoses are open to avoid the risk of unintended leakage of substances like e.g. fuel or oil.
