Fault diagnosis

Fault diagnosis


Before starting fault diagnosis, observe the following points:

Warning

No tests or connections are to be made on the SRS before the airbags have been disconnected.



• Read through the Safety and handling instructions.

• Turn off the ignition and remove the negative cable on the battery.

• Remove the connector on the back of the driver's airbag and passenger airbag.

• Connect reference resistor 84 71 153 to the relevant connector.

• When fault diagnosing the seat-belt tensioners, connect the reference resistor 84 71 153 to the respective connector on the seat-belt tensioners.

Also note the following:

• Splicing SRS cables is forbidden. Splicing can cause functional disorders that can make the system unusable and in extreme cases lead to personal injury.

• If a connector is unplugged while the ignition is switched on it will be recorded as a fault by the control module. The fault will not disappear until the connector is plugged in again and the diagnostic trouble code has been cleared.
