B1635

SUPPLEMENTAL RESTRAINT SYSTEM: AIRBAG SYSTEM: B1635/24: Rear Airbag Sensor LH Circuit Malfunction
B1635/24 - Rear Airbag Sensor LH Circuit Malfunction

DESCRIPTION

The rear airbag sensor LH consists of the diagnostic circuit, the lateral deceleration sensor, etc.

If the center airbag sensor assembly receives signals from the lateral deceleration sensor, it determines if the airbag should be deployed.

DTC B1635/24 is stored when a malfunction is detected in the rear airbag sensor LH circuit.

INSPECTION PROCEDURE

PROCEDURE

1. CHECK REAR AIRBAG SENSOR LH

(a) Turn the engine switch off.





(b) Disconnect the negative (-) terminal cable from the battery, and wait for at least 90 seconds.

(c) Interchange the rear airbag sensor RH with LH and connect the connectors to them.

(d) Connect the negative (-) terminal cable to the battery, and wait for at least 2 seconds.

(e) Turn the engine switch on (IG), and wait for at least 60 seconds.

(f) Clear the DTCs stored in the memory Reading and Clearing Diagnostic Trouble Codes.

(g) Turn the engine switch off.

(h) Turn the engine switch on (IG), and wait for at least 60 seconds.

(i) Check for DTCs Reading and Clearing Diagnostic Trouble Codes.

Result:





HINT
Codes other than DTC B1630/23 and B1635/24 may be output at this time, but they are not related to this check.

A -- CHECK CENTER AIRBAG SENSOR ASSEMBLY

B -- REPLACE REAR AIRBAG SENSOR LH Removal

C -- USE SIMULATION METHOD TO CHECK Diagnosis System

2. CHECK CENTER AIRBAG SENSOR ASSEMBLY

(a) Turn the engine switch off.





(b) Disconnect the negative (-) terminal cable from the battery, and wait for at least 90 seconds.

(c) Return the rear airbag sensor RH and LH to their original positions and connect the connectors to them.

(d) Connect the negative (-) terminal cable to the battery, and wait for at least 2 seconds.

(e) Turn the engine switch on (IG), and wait for at least 60 seconds.

(f) Clear the DTCs stored in the memory Reading and Clearing Diagnostic Trouble Codes.

(g) Turn the engine switch off.

(h) Turn the engine switch on (IG), and wait for at least 60 seconds.

(i) Check for DTCs Reading and Clearing Diagnostic Trouble Codes.

OK:

DTC B1635/24 is not output.

HINT
Codes other than DTC B1635/24 may be output at this time, but they are not related to this check.
