Acura RL (1996-2004 year). Manual — part 543
Troubleshooting
The troubleshooting flowchart procedures assume that the cause of the problem is still present and the ABS indicator
and/or VSA system indicator is still on. Following the flowchart when the ABS indicator and/or VSA system indicator does
not come on can result in incorrect diagnosis.
The connector illustrations show the female terminal connectors with a single outline and the male terminal connectors
with a double outline.
1. Question the customer about the conditions when the problem occurs, and try to reproduce the same conditions for
troubleshooting. Find out when the ABS indicator and/or VSA system indicator came on, such as during ABS control,
after ABS control, when vehicle speed was at a certain speed, etc.
2. When the ABS indicator or VSA system indicator does not come on during the test drive, but troubleshooting is per-
formed based on the DTC, check for loose connectors, poor contact of the terminals, etc. before you start troubleshoot-
ing.
3. After troubleshooting, clear the DTC, and test drive the vehicle. Make sure the ABS indicator and VSA system indicator
do not come on.

DTC Indication
NOTE: This operation can also be done with the Honda PGM Tester.
1. Connect the SCS service connector to the service check connector (2P) under the glove box.

• If the DTC is not memorized, the ABS indicator will go off for 3.6 seconds, and then come back on.
• If the ABS indicator stays on, troubleshoot for ABS indicator does not go off (see page
).
4. Turn the ignition switch OFF, and remove the SCS service connector.
NOTE: The Malfunction Indicator Lamp (MIL) will stay on after the engine is started if the SCS service connector is con-
nected.
