DIAGNOSIS SENSOR UNIT

Removal and Installation


WARNING:
Always observe the following items for preventing accidental activation.
- Before servicing the SRS, turn the ignition switch off, disconnect both 12V battery terminals and wait at least three minutes.
- Before disconnecting the air bag diagnosis sensor unit harness connectors, be sure to disconnect each harness connector of the seat belt pre-tensioners and lap pre-tensioner to prevent air bag deployment by static electricity and seat belt pre-tensioner operation.
- Never use air tools or electric tools for servicing.
- When replacing the air bag diagnosis sensor unit, always check with the parts department for the latest parts information. Installing an incorrect air bag diagnosis sensor unit may or may not cause the air bag warning lamp to illuminate and may cause incorrect deployment of the supplemental air bags and seat belt pre-tensioners in a collision resulting in serious personal injury or death.

REMOVAL

1.Always check the air bag diagnosis sensor unit ECU discriminated number (identification number) or part number using CONSULT.
2.Disconnect the negative and positive 12V battery terminals and wait at least three minutes. Refer to "Removal and Installation" .
3.Remove the center console assembly. Refer to "Removal and Installation" .
4.Disconnect the harness connectors for the following SRS components: SB-8, "SEAT BELT RETRACTOR
: Removal and Installation" (front seat belt pre-tensioners and lap pre-tensioner).





5.Disconnect the diagnosis sensor unit harness connectors (A).
6.Remove the diagnosis sensor unit mounting bolts (B), and then remove the diagnosis sensor unit.






CAUTION:





- To prevent damage to the parts, never impact the diagnosis sensor unit.


- Replace the diagnosis sensor unit if it is dropped or sustains an impact.
- Replace the diagnosis sensor unit of deployed SRS air bag and deployed SRS front seat belt pre-tensioner.

INSTALLATION

Note the following items, and then install in the reverse order of removal.

CAUTION:
- Never reuse bolts after removal, replace with new bolts.
- Never damage the harness while installing.
- If malfunction is detected by the air bag warning lamp, after repair or replacement of the malfunctioning parts, reset the memory using self-diagnosis or CONSULT. Refer to "On Board Diagnosis Function" or "CONSULT Function" {[SRC-15, "CONSULT Function"]LINK_TO:[0000000000000000]}.
- After the work is completed, check that no system malfunction is detected by air bag warning lamp.
- After replacing the air bag diagnosis sensor unit, confirm using CONSULT that the ECU discriminated number (identification number) or part number of the new replacement air bag sensor unit matches the ECU discriminated number (identification number) or part number of the replaced (old)
air bag diagnosis sensor unit.
NOTE:
If the ECU discriminated number or part number of the new replacement air bag diagnosis sensor unit differs from the ECU discriminated number or part number of the replaced air bag diagnosis sensor unit, reconfirm the parts information and verify that the correct air bag diagnosis sensor unit is installed.
