Acura RL (1996-2004 year). Manual — part 696
DTC 9-2 (cont'd)
Troubleshooting - '96 - 98 Models
Check for an open in the SRS main harness:
1. Disconnect the battery negative cable, then disconnect
the positive cable, and wait for 3 minutes.
2. Disconnect the driver's and front passenger's airbag con-
nectors, then disconnect the driver's and front passen-
ger's seat belt tensioner connectors (see page
).
3. Disconnect the SRS main harness 18P connector from
the SRS unit.
4. Reconnect the battery positive cable, then reconnect the
negative cable.
5. Connect a voltmeter between the No. 3 terminal of the
SRS main harness 18P connector and ground.
6. Turn the ignition switch ON (II), and measure voltage.

Self-diagnostic Procedures
The self-diagnostic function of the SRS system allows it to locate the causes of system problems and to store this informa-
tion 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 6 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 bat-
tery is disconnected.
• When you connect the SCS service connector to the service check connector (2P), 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 its 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 3 minutes, be careful not to bump the SRS
unit or the side impact sensor; the airbags or the side 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.
• Before you remove the SRS floor harness, disconnect both seat belt tensioner 2P connectors, and disconnect both side
airbag 2P connectors.
• Make sure the battery is sufficiently charged (see
). 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 special tools.

Reading the DTC
When the SRS indicator light is on, read the DTC using one of these methods:
Reading With the PGM Tester
Connect the Honda PGM Tester to the 16P Data Link Connector (DLC), and follow the tester's prompts. If the tester indi-
cates no DTC, DTC 9-1 or DTC 9-2, double-check by jumping the service check connector and watching the SRS indicator
light (see next page).
