DIAGNOSIS
INTRODUCTION TO ASC DIAGNOSIS
M1355000800065
The active stability control system (ASC) operates
differently from conventional brake systems. These
differences include sounds, sensations, and vehicle
performance that owners and service technicians
who are not familiar with ASC may not be used to.
Some operational characteristics may seem to be
malfunctions, but they are simply signs of normal
ASC operation. When diagnosing the ASC system,
keep these operational characteristics in mind.
Inform the owner of the kind of performance charac-
teristics to expect from an ASC-equipped vehicle.
ASC DIAGNOSTIC TROUBLE CODE
DETECTION CONDITIONS
ASC diagnostic trouble codes (ASC DTCs) are set
under different conditions, depending on the mal-
function detected. Most ASC DTCs will only be set
during vehicle operation. Some ASC DTCs will also
be set during the ASC self-check immediately after
the engine is started.
When you check if an ASC DTC will be displayed
again after the DTC has been erased, you should
duplicate the ASC DTC set conditions. Depending on
the detection timing and set conditions for the spe-
cific ASC DTC, you must either drive the vehicle or
turn the engine off and restart it. To set the proper
conditions for that DTC again, refer to "ASC DTC
SET CONDITIONS" for each ASC DTC that you are
trying to reset.
ASC DIAGNOSTIC TROUBLESHOOTING STRATEGY
M1355000900170
Use these steps to plan your diagnostic strategy. If
you follow them carefully, you will be sure that you
have exhausted most of the possible ways to find an
ASC fault.
1. Gather information about the problem from the
customer.
2. Verify that the condition described by the
customer exists.
3. Check the vehicle for any ASC DTC.
4. If you cannot verify the condition and there are no
ASC DTCs, the malfunction is intermittent. Refer
to GROUP 00, How to use
Troubleshooting/Inspection Service Points
− How
to Cope with Intermittent Malfunctions
.
5. If you can verify the condition but there are no
ASC DTCs, or the system cannot communicate
with the scan tool, check that the basic brake
system is operating properly.
• If the basic brake system is not operating prop-
erly, refer to the GROUP 35A, Basic Brake Sys-
tem Diagnostic troubleshooting strategy
• If the basic brake system is operating properly,
6. If there is an ASC DTC, record the number of the
DTC, then erase the DTC from the memory using
the scan tool.
7. Recreate the ASC DTC set conditions to see if the
same ASC DTC will set again.
• If the same ASC DTC sets again, perform the
diagnostic procedures for the DTC. Refer to
• If you cannot get the same ASC DTC to set
again, the malfunction is intermittent. Refer to
GROUP 00, How to use Troubleshooting/Inspec-
tion Service Points
− How to Cope with Intermit-
tent Malfunctions
