Installing a passenger airbag
1. Install the airbag into the dashboard,
2. Tighten the 2 bolts into the instrument panel. Tightening torque 18 Nm.
3. Install the removed parts.
Removal the SRS sensor
1. Remove the center console trim and center console.
2. Remove the airbag sensor.
- a) Disconnect the connector.
- b) Unscrew 3 bolts and remove the sensor.
1 - center console trim, 2 - airbag sensor, 3 - center console
Installing the SRS sensor
1. Install the sensor, tighten the three bolts. Tightening torque 21 Nm.
2. Connect the connector.
3. Install the removed parts.
System diagnostics
1. Checking the airbag system warning light.
Turn the ignition switch to the "ACC" or "ON" position, check that the indicator lamp comes on and goes out after about 6 seconds.
Note: If the indicator comes on occasionally or remains on even when the ignition switch is in the "OFF" position, check for a short circuit in the indicator lamp.
2. Reading fault codes.
- c) Set the ignition switch to the "ACC" or "ON" position and wait approximately 20 seconds.
- b) Short-circuit the terminals "Tc" and "E1" of the diagnostic connector.
Note: Incorrect connection of terminals may cause system failure.
- c) If there is no fault, the indicator will flash 1-2 times per second.
- d) If there is a fault, the indicator will start flashing at a variable frequency. Determine the fault codes.
Note:
- For trouble code definition, see ABS diagnostics.
- When two or more fault codes are displayed, they are displayed starting with the lowest number.
- If a code not listed in the table is displayed, the airbag sensor is faulty.
