is too low when ignition switch ON.
DTC Troubleshooting
Step
1
Was "Electronic Stability Program Check" performed?
2
DTC check for ESP®
1) Connect scan tool to DLC with ignition switch turned
OFF.
2) Turn ignition switch ON and check DTC for ESP®.
Are DTC C1057 and/or C1073 detected?
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?
