3.INSPECT AIRBAG CUT-OFF SWITCH |
Disconnect the E68 passenger airbag manual cut-off switch connector.
Measure the resistance of the wire harness side connector.
- Standard resistance:
Tester Connection Switch Condition Specified Condition 1 (PMC-) - 2 (PMC+) OFF 80 to 120 Ω 1 (PMC-) - 2 (PMC+) ON 320 to 480 Ω
|
| ||||
OK | |
4.CHECK INSTRUMENT PANEL WIRE (FOR OPEN) |
Disconnect the instrument panel wire connector from the airbag cut-off switch.
Using a service wire, connect E68-1 (PMC-) and E68-2 (PMC+) of connector C.
- NOTICE:
- Do not forcibly insert the service wire into the terminals of the connector when connecting.
Measure the resistance of the wire harness side connector.
- Standard resistance:
Tester Connection Specified Condition E49-11 (MSW+) - E49-12 (MSW-) Below 1 Ω
|
| ||||
OK | |
5.CHECK INSTRUMENT PANEL WIRE (FOR SHORT) |
Disconnect the service wire from connector C.
Measure the resistance of the wire harness side connector.
- Standard resistance:
Tester Connection Specified Condition E49-11 (MSW+) - E49-12 (MSW-) 1 MΩ or higher
|
| ||||
OK | |
6.CHECK INSTRUMENT PANEL WIRE (TO B+) |
Connect the cable to the negative (-) battery terminal, and wait for at least 2 seconds.
Turn the ignition switch on (IG).
Measure the voltage of the wire harness side connector.
- Standard voltage:
Tester Connection Specified Condition E49-11 (MSW+)- Body ground Below 1 V E49-12 (MSW-) - Body ground Below 1 V
|
| ||||
OK | |
7.CHECK INSTRUMENT PANEL WIRE (TO GROUND) |
Turn the ignition switch off.
Disconnect the cable from the negative (-) battery terminal, and wait for at least 90 seconds.
Measure the resistance of the wire harness side connector.
- Standard resistance:
Tester Connection Specified Condition E49-11 (MSW+) - Body ground 1 MΩ or higher E49-12 (MSW-) - Body ground 1 MΩ or higher
