SRS Indicator Light: Description and Operation
The self-diagnostic function of the SRS system allows it to locate the causes of system problems and then store this information in memory. For easier
troubleshooting, this data can be retrieved via a data link circuit.
When you turn the ignition switch ON (II), the SRS indicator will come on. If it goes off after six seconds, the system is normal.
If there is an abnormality, the system locates and defines the problem, stores this information in memory, and turns the SRS indicator light on. The data
will remain in the memory even when the ignition switch is turned off or if the battery is disconnected.
When you connect the Honda PGM Tester to the 16P data link connector (DLC) to short the SCS terminal, and turn the ignition switch ON (II).The SRS
indicator light will indicate the diagnostic trouble code (DTC) by the number of blinks.
After reading and recording the DTC, proceed with the troubleshooting for this code.
Precautions
Use only a digital multimeter to check the system. If it's not a Honda multimeter, make sure it's output is 10 mA (0.01 A) or less when switched to the
smallest value in the ohmmeter range. A tester with a higher output could damage the airbag circuit or cause accidental airbag deployment and possible
injury.
Whenever the ignition switch is ON (II), or has been turned OFF for less than three minutes, be careful not to bump the SRS unit; the airbags could
accidentally deploy and cause damage or injuries.
Before you remove the SRS main harness, disconnect the driver's airbag connector and the front passenger's airbag connector.
Make sure the battery is sufficiently charged. If the battery is dead or low, measuring values won't be correct.
Do not touch a tester probe to the terminals in the SRS unit or harness connectors, and do not connect the terminals with a jumper wire. Use only the
backprobe set and the Honda PGM Tester. Backprobe spring-loaded lock type connectors, correctly.
