4F-32 Electronic Stability Program:
Step
4
Check yaw rate / G sensor assembly power supply
circuit
1) Measure voltage between connector terminal "L39-3"
and "L39-5" with ignition switch turned ON.
Is it 10 – 14 V?
5
Check yaw rate / G sensor assembly power supply
circuit
1) Turn ignition switch to OFF position.
2) Disconnect ESP® control module connector.
3) Check for proper connection to ESP® control module
connector terminals at "E53-31" and "E53-37".
4) If OK, then measure voltage between connector terminal
"E53-37" and vehicle body ground with ignition switch
turned ON.
Is it 12 V?
6
Check yaw rate / G sensor assembly power supply
circuit
1) Measure resistance between the following points.
• Between terminal "E53-37" of module connector and
terminal "L39-3" of sensor terminal.
• Between terminal "E53-31" of module connector and
terminal "L39-5" of sensor terminal.
Are resistance less than 2
