DTC 024

Step	Action	Values	Yes	No
CAUTION: Refer to SDM Voltage After Ignition Is Turned OFF Caution in Cautions and Notices. CAUTION: Refer to Sensing and Diagnostic Module Handling Caution in Cautions and Notices.
1	Perform the Diagnostic System Check - SIR. Is the Diagnostic System Check - SIR complete?	-	Go to Step 2	Go to Diagnostic System Check - SIR
2	Inspect the fuse F8. Is the fuse open?	-	Go to Step 3	Go to Step 4
3	Inspect for a short circuit. Repair if needed. Replace the fuse. Is the repair complete?	-	Go to Diagnostic System Check - SIR	-
4	Turn the ignition ON. Using a multimeter, measure the voltage at the fuse F8. Is the battery voltage available at the fuse F8?	11-14 V	Go to Step 6	Go to Step 5
5	Repair the power supply to the fuse F8. Is the repair complete?	-	Go to Diagnostic System Check - SIR	-
6	Disconnect the negative battery cable. Wait 1 minute before proceeding. Disconnect the connector at the sensing and diagnostic module (SDM). Reconnect the battery. Turn the ignition key ON. Measure the voltage at the terminal 5 of the SDM connector. Is the voltage equal to the specified value?	11-14 V	Go to Step 7	Go to Step 8
7	Replace the SDM. Reconnect the electrical connectors. Is the repair complete?	-	Go to Diagnostic System Check - SIR	-
8	Disconnect the connector C214. The connector C214 is the connector between the instrument harness and the supplemental inflatable restraint (SIR) harness. Turn the ignition ON. Using a multimeter, measure the voltage on the instrument harness side at terminal 3 of the connector C214. Is the voltage equal to the specified value?	11-14 V	Go to Step 9	Go to Step 10
9	Replace the SIR wiring harness. Reconnect the battery. Is the repair complete?	-	Go to Diagnostic System Check - SIR	-
10	Repair the open circuit between the fuse F8 and the connector C214. Is the repair complete?	-	Go to Diagnostic System Check - SIR	-
