Dodge Caliber. Manual - part 151

If the amber ABS warning indicator is on, road test the vehicle as described below. While only the amber ABS
warning indicator is on, the ABS is not functional. The ability to stop the car using the base brake system should not
be affected.

6. Turn the key to the OFF position and then back to the ON position. Note whether the amber ABS warning indi-

cator lamp continues to stay on.

7. If the amber ABS warning indicator lamp stays on, shift into gear and drive the car to a speed of approximately

15 mph (25 km/h) to complete the ABS Start-Up and Drive-Off Cycles (Refer to 5 - BRAKES - ABS - OPERA-
TION). If at this time the amber ABS warning indicator lamp stays on, refer to the appropriate diagnostic infor-
mation.

8. If the amber ABS warning indicator lamp goes out at any time, drive the vehicle a short distance. Accelerate the

vehicle to a speed of at least 64 km/h (40 mph). Bring the vehicle to a complete stop, braking hard enough to
cause the ABS to cycle. Repeat this action several times. Using the scan tool, read and record any Diagnostic
Trouble Codes (DTCs). If any DTCs are present, refer to the appropriate diagnostic information.

STANDARD PROCEDURE

ANTILOCK BRAKE SYSTEM BLEEDING

The base brake’s hydraulic system must be bled anytime air enters the hydraulic system. The ABS must always be
bled anytime it is suspected that the HCU has ingested air.

Brake systems with ABS must be bled as two independent braking systems. The non-ABS portion of the brake
system with ABS is to be bled the same as any non-ABS system.

The ABS portion of the brake system must be bled separately. Use the following procedure to properly bleed the
brake hydraulic system including the ABS.

NOTE: During the brake bleeding procedure, be sure the brake fluid level remains close to the FULL level in
the master cylinder fluid reservoir. Check the fluid level periodically during the bleeding procedure and add
Mopar

DOT 3 brake fluid as required.

BLEEDING

When bleeding the ABS system, the following bleeding sequence must be followed to insure complete and adequate
bleeding.

1. Make sure all hydraulic fluid lines are installed and properly torqued.

2. Connect the scan tool to the diagnostics connector. The diagnostic connector is located under the lower steering

column cover to the left of the steering column.

3. Using the scan tool, check to make sure the ABM does not have any fault codes stored. If it does, clear them.

WARNING: When bleeding the brake system wear
safety glasses. A clear bleed tube (1) must be
attached to the bleeder screws and submerged in
a clear container filled part way with clean brake
fluid (2). Direct the flow of brake fluid away from
yourself and the painted surfaces of the vehicle.
Brake fluid at high pressure may come out of the
bleeder screws when opened.

NOTE: Pressure bleeding is recommended to bleed the base brake system to ensure all air is removed from
system. Manual bleeding may also be used, but additional time is needed to remove all air from system.

4. Bleed the base brake system. (Refer to 5 - BRAKES - BASE - STANDARD PROCEDURE)

5. Using the scan tool, select ECU VIEW, followed by ABS MISCELLANEOUS FUNCTIONS to access bleeding.

Follow the instructions displayed. When finished, disconnect the scan tool and proceed.

6. Bleed the base brake system a second time. Check brake fluid level in the reservoir periodically to prevent emp-

tying, causing air to enter the hydraulic system.

7. Fill the master cylinder fluid reservoir (1) to the

FULL level.

8. Test drive the vehicle to be sure the brakes are

operating correctly and that the brake pedal does
not feel spongy.

SENSOR-DYNAMICS (ESP)

DESCRIPTION

The Yaw Rate and Lateral Acceleration Sensors are
housed into one unit known as the Dynamics Sensor
(1). The sensor is used to measure side-to-side (Lat-
eral) motion and vehicle rotational sensing (how fast
the vehicle is turning - Yaw).

Yaw and Lateral Acceleration Sensors cannot be ser-
viced separately. The entire Dynamics Sensor must be
replaced when necessary.

REMOVAL

1. Disconnect and isolate the battery negative cable from the battery post.

2. Remove the shifter housing center console. (Refer to 23 - BODY/INTERIOR/CENTER CONSOLE - REMOVAL)

3. Disconnect the wiring harness connector (3) at the

dynamics sensor (1).

4. Remove the nuts (2) mounting the dynamics sen-

sor to the floor pan tunnel (4).

5. Remove the dynamics sensor (1).

INSTALLATION

1. Install the dynamics sensor (1) over the studs

mounted to the floor pan tunnel (4).

2. Install the two mounting nuts (2). Tighten the nuts

to 9 N·m (80 in. lbs.).

3. Connect the wiring harness connector (3) to the

dynamics sensor (1).

4. Install the shifter housing center console. (Refer to

BODY/INTERIOR/CENTER

CONSOLE

INSTALLATION)

5. Connect the battery negative cable to the battery

post. It is important that this be performed properly.
(Refer to 8 - ELECTRICAL/BATTERY SYSTEM -
STANDARD PROCEDURE)

6. Perform the Verification Test and clear any faults.
