DESCRIPTION The front airbag sensor RH circuit consists of the airbag sensor assembly and front airbag sensor RH. The front airbag sensor RH detects impacts to the vehicle and sends signals to the airbag sensor assembly to determine if the airbag should be deployed. DTC B1612 or B1613 is stored when a malfunction is detected in the front airbag sensor RH circuit.
WIRING DIAGRAM CAUTION / NOTICE / HINT NOTICE:
PROCEDURE
(a) Turn the ignition switch off. (b) Disconnect the cable from the negative (-) battery terminal, and wait for at least 90 seconds. (c) Check that the connectors are properly connected to the airbag sensor assembly and front airbag sensor RH. OK: The connectors are properly connected.
(a) Disconnect the connectors from the airbag sensor assembly and front airbag sensor RH.
(b) Turn the ignition switch to ON. (c) Measure the voltage according to the value(s) in the table below. Standard Voltage:
(d) Turn the ignition switch off. (e) Disconnect the cable from the negative (-) battery terminal, and wait for at least 90 seconds. (f) Using a service wire, connect terminals 29 (+SR) and 28 (-SR) of connector B. NOTICE: Do not forcibly insert the service wire into the terminals of the connector when connecting a service wire. (g) Measure the resistance according to the value(s) in the table below. Standard Resistance:
(h) Disconnect the service wire from connector B. (i) Measure the resistance according to the value(s) in the table below. Standard Resistance:
(b) Interchange the front airbag sensor RH with LH and connect the connectors to them. (c) Connect the cable to the negative (-) battery terminal, and wait for at least 2 seconds. (d) Turn the ignition switch to ON, and wait for at least 60 seconds. (e) Clear the DTCs stored in memory. Click here (f) Turn the ignition switch off. (g) Turn the ignition switch to ON, and wait for at least 60 seconds. (h) Check for DTCs. Click here
HINT: Codes other than DTC B1612, B1613, B1617 and B1618 may be output at this time, but they are not related to this check. (i) Turn the ignition switch off. (j) Disconnect the cable from the negative (-) battery terminal, and wait for at least 90 seconds. (k) Return the front airbag sensor LH and RH to their original positions and connect the connectors to them.
(b) Connect the cable to the negative (-) battery terminal, and wait for at least 2 seconds. (c) Turn the ignition switch to ON. (d) Measure the voltage according to the value(s) in the table below. Standard Voltage:
(e) Turn the ignition switch off. (f) Disconnect the cable from the negative (-) battery terminal, and wait for at least 90 seconds. (g) Using a service wire, connect terminals 29 (+SR) and 28 (-SR) of connector B. NOTICE: Do not forcibly insert the service wire into the terminals of the connector when connecting a service wire. (h) Measure the resistance according to the value(s) in the table below. Standard Resistance:
(i) Disconnect the service wire from connector B. (j) Measure the resistance according to the value(s) in the table below. Standard Resistance:
