Step Action Yes No
1 Was “Electronic Stability Program Check” performed? Go to Step 2. Go to “Electronic
Stability Program
Check: ”.
2 DTC check for ESP
®
1) Connect scan tool to DLC with ignition switch turned

2) Turn ignition switch ON and check DTC for ESP
®
.
Are DTC C1057 and/or C1073 detected?
Go to applicable DTC
diag. flow. Go to Step 3.
3 Check yaw rate / G sensor assembly power supply
circuit
1) Turn ignition switch to OFF position.
2) Disconnect yaw rate / G sensor assembly connector.
3) Check for proper connection to yaw rate / G sensor
assembly connector terminals at “L39-3” and “L39-5”.
4) If OK, then measure voltage between connector terminal
“L39-3” and vehicle body ground.
Is it 0 V?
Go to Step 4. Go to Step 5.
