or accidentally.
2. The SRS-ECU, the driver’s side air bag module, the passenger side air bag module, the pre-tensio\
ner fitted seatbelts and the clock spring, should be removed if there is a chance o\
f them being affected by heat during
painting work.
• 93ºC and above: the SRS-ECU, the driver’s air bag module, the passenger’s air bag module and the clock spring should be removed.
• 90ºC and above: the pre-tensioner fitted seatbelts should be rem\
oved.

Inspection guidelines and troubleshooting
With the introduction of new settings for the MB992006 (Extra Fine Probe) special tool, the guidelines for inspecting the
connector have been changed. Other servicing guidelines remain unchanged.
Making an inspection with the connector
attached (so the electrical circuit is complete)

The test bar should be inserted from the harness side. If the control
unit or the connector is too small, and the test bar cannot be
inserted, do not attempt to force it in. Instead, use the MB992006
(Extra Fine Probe) special tool.
