Wiring Diagram
DTC Detecting Condition and Trouble Area
4 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 “E85-31” and “E85-37”.
4) If OK, then measure voltage between connector terminal
“E85-37” and vehicle body ground.
Is it 0 V?
Go to Step 5. “BLU/RED” wire circuit
is shorted to power
circuit.
5 Check yaw rate / G sensor assembly power supply
circuit
1) Measure resistance between the following points.
• Between terminal “E85-37” of module connector and
terminal “E84-3” of sensor terminal.
• Between terminal “E85-31” of module connector and
terminal “E84-5” of sensor terminal.
Are resistance less than 2
Ω ?
Substitute a known-
good ESP® hydraulic
unit / control module
assembly recheck.
“BLU/RED” and/or
“GRN/BLK” wire circuit
open or high resistance.
