TROUBLESHOOTING GUIDE
The AAS control unit has a self-diagnosis function detecting the unit itself, electrical parts for AAS sys-
tem, and wiring harness open circuit, to inform mechanics. If it detects their malfunctions, outputs the
output pattern to A (LW) terminal of service connector according to the settled pattern for each mal-
function.
Troubleshooting against AAS system can be conducted by knowing the output pattern (See page 15—96,
97) to detect trouble location. 76gisx-o2o
TROUBLESHOOTING
How To Use Self-Diagnosis System
By using the control unit's self-diagnosis function and
a voltmeter, malfunctions of the system are easily de-
termined. When diagnosing malfunctions, follow the
steps bellow.
1. Connect a voltmeter to A (LW) terminal of the serv-
ice connector in engine room.
2. Read out the output patterns (See page 15—96)
in following condition.
