Intermittent fault
- Ignition off.WARNING:
Never use an ohmmeter or any other charged measuring instrument on a disconnected, undeployed explosive inflatable curtain. There is a risk that the inflatable curtain could be deployed
CAUTION:Avoid touching the contact pins in the supplemental restraint system (SRS) control unit. There is a risk of an electrostatic discharge which can cause damage to the supplemental restraint system (SRS) control unit.
Check the supplemental restraint system (SRS) control unit connector and the inflatable curtain connector for contact resistance and oxidation as described in Contact resistance and oxidation and for a loose contact as described in Loose connections (terminals) .
Check the wire between the supplemental restraint system (SRS) control unit 21A (21), 22A (22) and connector 1, 3 on the left inflatable curtain for an intermittent short circuit to voltage supply as described in Short-circuit to supply voltage, intermittent faults .
Do the necessary corrective action.
Additional information:
- To access/replace SRS control unit connector, see Supplemental restraint system module (SRS), replacing
- To access/replace the left inflatable curtain connector, see IC (inflatable curtain) module, replacing
- To connect the test box, see Connecting the breakout box
- With ignition off and the left inflatable curtain connector disconnected and SRS control unit connector disconnected, the resistance between the inflatable curtain connector 1, 3 (to the supplemental restraint system (SRS) control unit) and the disconnected battery connection should be infinite
