SIR Caution

Circuit Description

When you first turn ON the ignition, the inflatable restraint sensing and diagnostic module (SDM) performs tests to diagnose critical malfunctions within itself. Then the SDM performs the following continuous diagnostic tests on the deployment loops:

•	Deployment loop voltage out of range test

•	Deployment loop resistance measurement test

If the voltage out of range test detects a short to voltage condition, the resistance measurement test for that deployment loop will not be performed.

Conditions for Running the DTC

•	Ignition 1 voltage is within the normal operating voltage range.

•	Passenger frontal deployment loop is not open.

•	Passenger frontal deployment loop is not shorted to voltage.

•	Passenger frontal deployment loop is not shorted to ground.

Conditions for Setting the DTC

Passenger frontal deployment loop resistance is less than 1.3 ohms for 300 milliseconds.

Action Taken When the DTC Sets

The SDM commands ON the AIR BAG warning lamp via Class 2 serial data.

Conditions for Clearing the DTC

•	You can issue a CLEAR CODES command

•	A history DTC will clear once 255 malfunction free ignition cycles have occurred

Diagnostic Aids

The following can cause an intermittent condition:

•	A short between the passenger frontal high and the passenger frontal low circuits.

•	A malfunctioning shorting bar on the inflatable restraint IP module 2-way connector.

•	A malfunctioning shorting bar on the 4-way inline connector.

•	Refer to cell-id="62112">Testing for Intermittent and Poor Connections> in Wiring Systems.

Test Description

The number(s) below refer to the step number(s) on the diagnostic table.

This step checks the inline connector C218.

This step isolates the malfunction to one side of inline connector C218.

This step checks the inflatable restraint IP module yellow 2-way connector.

This step determines if there is a short between the passenger frontal high and passenger frontal low circuits in the wiring harness between the inflatable restraint IP module yellow 2-way connector and inline connector C218 or if there is a malfunctioning inflatable restraint IP module.

This step determines if there is a short between the passenger frontal high and passenger frontal low circuits in the wiring harness between inline connector C218 and the SDM wiring harness connector or if there is a malfunctioning SDM.

Did you perform A Diagnostic System Check - SIR?

Go to Step 2

Go to cell-id="57882">A Diagnostic System Check - SIR>

Turn OFF the ignition.
Disconnect the 4-way inline connector C218.
Inspect the male and female sides of inline connector C218 for the following conditions:

•

Corrosion

•	Damaged terminals

•	Poor connections/terminal tension

Refer to cell-id="62112">Testing for Intermittent and Poor Connections> in Wiring Systems.

Does either the male or female side of inline connector C218 exhibit any signs of corrosion, terminal damage, or poor connections?

Go to Step 3

Go to Step 4

If the female side of the inline connector is damaged, the wiring harness must be replaced.
If the male side of the inline connector is damaged, replace the male side of the connector. Refer to cell-id="61973">Connector Repairs> in Wiring Systems.

Did you complete the repair?

Go to Step 14

Reconnect the 4-way inline connector C218.
Verify that the connector position assurance (CPA) is properly installed.
Turn ON the ignition, with the engine OFF.
Use the scan tool to request the SIR DTC display.

Does the scan tool indicate that this DTC is current?

Go to Step 5

Go to Diagnostic Aids

Turn OFF the ignition.
Disconnect the 4-way inline connector C218.
Use the J 38715-80 adaptor to connect the J 38715-A SIR Driver/Passenger Load Tool PASSENGER INFLATOR and BASE OF CLOUMN connectors to the male side of the 4-way inline connector C218.
Turn ON the ignition, with the engine OFF.
Use the scan tool to request the SIR DTC display.

Does the scan tool indicate that this DTC is current?

Go to Step 11

Go to Step 6

Turn OFF the ignition.
Disconnect the inflatable restraint IP module yellow 2-way connector. Refer to cell-id="57777">Inflatable Restraint Instrument Panel Module Replacement> .
Inspect the component and harness of the inflatable restraint IP module yellow 2-way connector for the following conditions:

•

Corrosion

•	Damaged terminals

•	Poor connections/terminal tension

Refer to cell-id="62112">Testing for Intermittent and Poor Connections> in Wiring Systems.

Does either the component or harness side of the inflatable restraint IP module yellow 2-way connector exhibit any signs of corrosion, terminal damage, or poor connections?

Go to Step 7

Go to Step 8

If the component side of the inflatable restraint IP module yellow 2-way connector is damaged, the inflatable restraint IP module must be replaced.
If the harness side of the inflatable restraint IP module yellow 2-way connector is damaged, replace the harness side of the connector. Refer to cell-id="61973">Connector Repairs> in Wiring Systems.

Did you complete the repair?

Go to Step 14

Turn OFF the ignition.
Remove the J 38715-A .
Reconnect the 4-way inline connector C218.
Connect the J 38715-A PASSENGER INFLATOR connector to the harness side of the inflatable restraint IP module yellow 2-way connector.
Turn ON the ignition, with the engine OFF.
Use the scan tool to request the SIR DTC display.

Does the scan tool indicate that this DTC is current?

Go to Step 9

Go to Step 10

Turn OFF the ignition.
Locate and repair the short between the passenger frontal high and passenger frontal low circuits in the wiring harness between the inflatable restraint IP module yellow 2-way connector and inline connector C218. Refer to cell-id="62194">Circuit Testing> and cell-id="61965">Wiring Repairs> in Wiring Systems.

Did you complete the repair?

Go to Step 14

Turn OFF the ignition.
Replace the inflatable restraint IP module. Refer to cell-id="57777">Inflatable Restraint Instrument Panel Module Replacement> .

Did you complete the replacement?

Go to Step 14

Turn OFF the ignition.
Remove the J 38715-A .
Disconnect the inflatable restraint sensing and diagnostic module (SDM) wiring harness connector C1. Refer to cell-id="57768">Inflatable Restraint Sensing and Diagnostic Module Replacement> or cell-id="57768">Inflatable Restraint Sensing and Diagnostic Module Replacement> .
Use the J 39200 Digital Multimeter (DMM) to measure the resistance between the passenger frontal high and the passenger frontal low circuits in the wiring harness between inline connector C218 and the SDM wiring harness connector C1.
