MONITOR SCAN TOOL DATA 

1. Connect scan tool to Data Link Connector (DLC).  

2. Ignition "ON".  

3. Monitor the "Yaw rate sensor-lateral & Yaw rate sensor-yaw" parameter on the scan tool. 

Specification: Lateral G sensor: ± 0 G, YAW rate Sensor: ± 0 deg/s

Case 1

Enable Conditions

> 4.7 V for a time t > = 
100ms.  



A line fault is detected if 
V[YAW] < 0.225 V OR 
V[YAW] > 4.774 V for a 
time t > = 100 ms.  



A line fault is detected if 
V[YAW REFERENCE] 
< 2.1 V OR V[YAW 
REFERENCE] > 2.9 V 
for a time t > = 200 ms.  



Inoperative Yaw 
Rate & Lateral G 
sensor  



Open or short of 
Yaw Rate & 
Lateral G sensor  



Inoperative HECU  

Case 2

DTC strategy



Self-test Monitoring  

Monitoring Period



Once after power up and 
no low voltage.  

Enable Conditions



A line fault is detected if 
0.2 V < V[LG] < 0.8 V 
isn't continued for a time 
t > = 60 ms during POS 
(POS: power on self-test) 

Fail Safe



4. Is parameter displayed within specifications? 

YES  



Fault is intermittent caused by poor connection in Yaw Rate & Lateral G sensor harness and/or 
HECU's connector or was repaired and HECU memory was not cleared. Thoroughly check 
connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or 
damage. Repair or replace as necessary and then go to "VERIFICATION OF VEHICLE 
REPAIR" procedure.  

NO  



Go to TERMINAL & CONNECTOR INSPECTION procedure.  

TERMINAL & CONNECTOR INSPECTION 

Refer to DTC C1102. 

POWER SUPPLY CIRCUIT INSPECTION 

1. Ignition "ON" & Engine "OFF".  

2. Measure voltage between terminal "1" of the Yaw Rate & Lateral G sensor harness connector and chassis 

ground. 

Specification: Approx. B+

3. Is the measured voltage within specifications? 

YES  



Go to "GROUND CIRCUIT INSPECTION" procedure.  

NO  



Check for open or short to GND in the Yaw Rate & Lateral G sensor harness between terminal "1" 
of the Yaw Rate & Lateral G sensor harness connector and battery +. Repair as necessary and then 
go to "VERIFICATION OF VEHICLE REPAIR" procedure.  

GROUND CIRCUIT INSPECTION 

1. Ignition "OFF".  

2. Disconnect Yaw Rate & Lateral G sensor connector.  

3. Measure resistance between terminal "4" of the Yaw Rate & Lateral G sensor harness connector and 

chassis ground. 

Specification: Approx. below 1ohms

4. Is the measured resistance within specifications? 

YES  



Go to "SIGNAL CIRCUIT INSPECTION" procedure.  

NO  



Check for open or short in the Yaw Rate & Lateral G sensor harness between terminal "4" of the 
Yaw Rate & Lateral G sensor harness connector and chassis ground. Repair as necessary and then 
go to "VERIFICATION OF VEHICLE REPAIR" procedure.  

SIGNAL CIRCUIT INSPECTION 

1. Ignition "ON" & Engine "OFF".  

2. Measure voltage between terminal "3,5,6" of the Yaw Rate & Lateral G sensor harness connector and 

chassis ground. 

Specification: Approx. 2.5 V ( Voltage between terminal "5, 6" of the Yaw Rate & Lateral G sensor 
harness connector and chassis ground.)

3. Is the measured voltage within specifications? 

YES  



Go to "SELF TEST CIRCUIT INSPECTION" procedure.  

NO  



Check for open or short in the Yaw Rate & Lateral G sensor harness between terminal "3, 5, 6" of 
the Yaw Rate & Lateral G sensor harness connector and terminal "16, 18, 20" of the chassis 
ground. Repair as necessary and then go to "VERIFICATION OF VEHICLE REPAIR" 
procedure.
