With Manufacturer's Scan Tool
Reading the DTCWhen the SRS indicator is on, read the DTC using either of the following methods:
HDS "SRS" Menu Method
Connect the HDS to the Data Link Connector (DLC) 16P (A), and follow the HDS prompts in the "SRS" menu. If the tester indicates no DTC, DTC 9-1 or DTC 9-2, double-check by using the "SCS" menu method.
HDS "SCS" Menu Method (retrieving flash codes)
The SRS indicator indicates the DTC by the number of blinks when the HDS is connected to the data link connector (DLC) 16P, and the SCS line is grounded.
1. Make sure the ignition switch is OFF.
2. Connect the HDS to the data link connector (DLC) 16P (A), and follow the HDS prompts in the "SCS" menu to ground the SCS line.
3. Make sure the SCS line is grounded, then turn the ignition switch ON (II). The SRS indicator (B) should come on for about 6 seconds, and then go off. Then it will blink to indicate DTCs (see the table).
- The DTC consists of a main code and a subcode.
- Including the most recent problem, up to three different DTCs can be indicated.
- In case of a continuous failure, the DTC will be indicated repeatedly (see example 1).
- In case of an intermittent failure, the SRS indicator will indicate the DTC one time, then it will stay on (see example 2).
- If a continuous and an intermittent failure occur, both DTCs will be indicated as continuous failures.
- In case the system is normal (no DTC), the SRS indicator will stay on (see example 3).
- If the SRS indicator does not come on as indicated above, always check for an open or a short to ground in the SCS circuit before troubleshooting the system.
4. Read the DTC.
5. Turn the ignition switch OFF, and wait for 10 seconds.
6. Disconnect the HDS from the data link connector (DLC) 16P.
7. Proceed with the troubleshooting procedure for the DTC.
