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

Are DTC U0073 and/or U0123 detected?
YES -
Go to applicable DTC troubleshooting.
NO -
Go to Step 3.

3. Check fuse

Is circuit fuse for yaw rate / G sensor in good condition?
YES -
Go to Step 4.
NO -
Replace fuse and check for short circuit to ground.

4. Check yaw rate / G sensor power supply circuit

Turn ignition switch to OFF position.
Disconnect yaw rate / G sensor connector.
Check for proper connection to yaw rate / G sensor connector terminals at "L34-1" and "L34-4".
If OK, then measure voltage between connector terminal "L34-1" and vehicle body ground with ignition switch turned ON.

Is it 10 - 14 V?
YES -
Go to Step 5.
NO -
"GRN/ORN" wire circuit open or high resistance.

5. Check yaw rate / G sensor ground circuit

Measure resistance between connector terminal "L34-4" and vehicle body ground with ignition switch turned OFF.

Is resistance less than 2 ohms?
YES -
Substitute a known-good yaw rate / G sensor and recheck. If DTC C1034 and/or C1039 is still detected, substitute a known-good ESP(R) hydraulic unit / control module assembly and recheck.
NO -
"BLK/ORN" wire circuit open or high resistance.
