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 ground as described in Short-circuit to ground, intermittent faults .
Do the necessary corrective action.
Additional information:
- To access/replace the supplemental restraint system (SRS) control unit and 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 left inflatable curtain connector and supplemental restraint system (SRS) control unit connector disconnected, the resistance between inflatable curtain connector 1, 3 (to supplemental restraint system (SRS) control unit) and ground should be infinite
