Wiring Diagram










DTC Detecting Condition and Trouble Area






DTC Troubleshooting

1.
Was "Electronic Stability Program Check" performed?
YES -
Go to Step 2.
NO -
Go to (ESP) Check Electronic Stability Program Check.

2. DTC check for ESP(R)

Connect scan tool to DLC with ignition switch turned OFF.
Turn ignition switch ON and check DTC for ESP(R).

Are DTC C1057 and/or C1073 detected?
YES -
Go to applicable DTC diag. flow.
NO -
Go to Step 3.

3. Check yaw rate / G sensor assembly power supply circuit

Turn ignition switch to OFF position.
Disconnect yaw rate / G sensor assembly connector.
Check for proper connection to yaw rate / G sensor assembly connector terminals at "L39-1" and "L39-4".
If OK, then measure voltage between connector terminal "L39-1" and vehicle body ground.

Is it 0 V?
YES -
Go to Step 4.
NO -
Go to Step 5.

4. Check yaw rate / G sensor assembly power supply circuit

Measure voltage between connector terminal "L39-1" and "L39-4" with ignition switch turned ON.

Is it 10 - 14 V?
YES -
Substitute a known-good yaw rate / G sensor assembly and recheck.
NO -
Go to Step 5.

5. Check yaw rate / G sensor assembly power supply circuit

Turn ignition switch to OFF position.
Disconnect ESP(R) control module connector.
Check for proper connection to ESP(R) control module connector terminals at "E53-29" and "E53-22".
If OK, then measure voltage between connector terminal "E53-22" and vehicle body ground with ignition switch turned ON.

Is it 0 V?
YES -
Go to Step 6.
NO -
"PNK/WHT" wire circuit is shorted to power circuit.

6. Check yaw rate / G sensor assembly power supply circuit

Measure resistance between the following points.
- Between terminal "E53-22" of module connector and terminal "L39-1" of sensor terminal.
- Between terminal "E53-29" of module connector and terminal "L39-4" of sensor terminal.

Are resistance less than 2 ohms?
YES -
Substitute a known-good ESP(R) hydraulic unit / control module assembly and recheck.
NO -
"PNK/WHT" and/or "PNK/GRN" wire circuit open or high resistance.
