DTC Detecting Condition and Trouble Area
DTC Detecting Condition
• Power supply voltage of yaw rate / G sensor assembly
is too high when ignition switch OFF.
• Power supply voltage of yaw rate / G sensor assembly
is too low when ignition switch ON.
DTC Troubleshooting
Step
1 Was "Electronic Stability Program Check" performed?
2 Check yaw rate / G sensor assembly ground 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 "E84-3" and "E84-5".
4) If OK, then measure voltage between connector terminal
"E84-3" and vehicle body ground.
Is it 0 V?
3 Check yaw rate / G sensor assembly power supply
circuit
1) Measure voltage between connector terminal "E84-3"
and "E84-5" with ignition switch turned ON.
Is it 10 – 14 V?
