Checking The Component

WARNING:

Under no circumstances use an ohmmeter or other live measuring instrument to take readings on a disconnected, non-deployed, pyrotechnical inflatable curtain. This could deploy the inflatable curtain

CAUTION:

Do not touch the terminal pins in the supplemental restraint system module (SRS). There is a risk of static discharge. This could damage the supplemental restraint system module (SRS).

Check cables and terminals if the diagnostic trouble code (DTC) is intermittent. Remedy as necessary and select alternative 1 at the bottom
If the diagnostic trouble code (DTC) is permanent, continue fault-tracing
Switch off the ignition. Wait 10 seconds
Disconnect the connector from the right-hand inflatable curtain
Connect a special tool to the connector (to the ignition cable). To carry out this procedure, use: see 9511506
NOTE:
The special tool must be checked and fault-free. If the special tool is faulty, the diagnostic readings will be incorrect. This will make fault-tracing harder.
Switch on the ignition. Wait 10 seconds.
Read diagnostic trouble codes using the VCT2000 (or appropriate scan tool).

If the diagnostic trouble code (DTC) changes status from a permanent to an intermittent fault, replace the right-hand inflatable curtain and select alternative 1 at the bottom.

If the diagnostic trouble code (DTC) is still permanent, select alternative 2 at the bottom.
