Diagnosis and Testing

Principle of Operation Published: 11-May-2011

For a detailed description of the wheels and tires, refer to the relevant Description and Operation section in the workshop
manual. REFER to: (204-04 Wheels and Tires)

Wheels and Tires (Description and Operation), Wheels and Tires (Description and Operation), Wheels and Tires (Description and Operation).
Inspection and Verification


CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not
guarantee confirmation of a fault, and may also cause additional faults in the vehicle being tested and/or the donor vehicle.

1. Verify the customer complaint. As much information as possible should be gathered from the driver to assist in
diagnosing the cause(s). Confirm which of the following two warning types (A or B) exist for the Tire Pressure
Monitoring System when the ignition status is switched from 'OFF' to 'ON'
(A) Check Tire Pressure Warnings. A low tire pressure warning will continuously illuminate the low tire
pressure warning lamp. This warning may be accompanied by a text message such as CHECK TIRE PRESSURE
(refer to owner literature). The manufacturer approved diagnostic system does NOT need to be used. Diagnostic
Trouble Codes (DTCs) are not generated with this type of warning. To extinguish this warning it is essential that,
with the ignition 'ON', all vehicle tires (including the spare) are to be set to the correct pressure as stated in the
vehicle handbook or as indicated on the placard label in the passenger/driver door aperture. It is not necessary
to drive the vehicle to clear 'check tire pressure' warnings - just changing the tire pressure causes the tire
low pressure sensor to transmit new data.
NOTES:

The tire pressures should be set by:
Using a calibrated tire pressure gauge
With 'cold' tires (vehicle parked in the ambient temperature for at least one hour, not in a garage with an
artificial ambient temperature)

If the tire pressure warning does not clear within two minutes, it is likely that the gauge is not correctly
calibrated or the tires are 'warm'. Carry out the following steps until the warning has cleared:

Increase the tire pressures by 3psi
Wait a further two minutes
When the tires are at ambient temperature and a calibrated gauge is available, reset the tire pressures
to the correct pressure.

Tire pressure adjustments are part of routine owner maintenance. Tire pressure adjustments that are
required due to a lack of owner maintenance are not to be claimed under vehicle warranty.

(B) System Fault Warnings. When a system fault is detected, the low tire pressure warning lamp will flash for
approximately 75 seconds prior to being continuously illuminated. Visually inspect for obvious signs of damage
and system integrity. Check for the presence of tire low pressure sensors on all four wheels (note: a tire low
pressure sensor has a metal valve stem rather than a rubber one).
2. Check for Diagnostic Trouble Codes (DTCs) and refer to the DTC Index.

NOTE: If the tester fails to communicate with the Tire Pressure Monitoring System module, the following actions are
recommended:

Remove the Tire Pressure Monitoring System power supply fuse, inspect and re-install (if intact). Test to see if
communications have been re-established.

Remove the Tire Pressure Monitoring System ignition fuse (if applicable), inspect and re-install (if intact). Test to see if
communications have been re-established.
With ignition status set to 'ON', refer to the electrical circuit diagrams and check Tire Pressure Monitoring System
module for power, ignition and ground supplies .
Carry out CAN network integrity test using the manufacturer approved diagnostic system.

CAUTION: When probing connectors to take measurements in the course of the pinpoint tests, use the adaptor kit, part
number 3548-1358-00

Does the brake pedal return to its original position? Yes
No action required, vehicle is OK.
No
GO to K2. K2: CHECK FOR BRAKE PEDAL BINDING 1 Disconnect the brake booster from the brake pedal. Check the brake pedal to ensure free operation. Is the brake pedal operating freely? Yes
Install a new brake booster as required. REFER to:
Brake Booster (206-07 Power Brake Actuation, Removal and Installation), Brake Booster - RHD (206-07, Removal and Installation).
Re-test the system for normal operation.
No
Repair or install new brake pedal. Re-test the system for normal operation. Component Tests

Brake Booster

1. Check all hoses and connections. All unused vacuum connectors should be capped. Hoses and their connections should
be correctly secured and in good condition with no holes and no collapsed areas. Inspect the valve on the brake booster
for damage.
2. Check the hydraulic brake system for leaks or low fluid.

3. With the automatic transmission in PARK, stop the engine and apply the parking brake. Pump the brake pedal several
times to exhaust all vacuum in the system. With the engine switched off and all vacuum in the system exhausted,
apply the brake pedal and hold it down. Start the engine. If the vacuum system is operating, the brake pedal will tend
to move downward under constant foot pressure. If no motion is felt, the vacuum booster system is not functioning.

4. Remove the vacuum hose from the brake booster. Manifold vacuum should be available at the brake booster end of the
hose with the engine at idle speed and the automatic transmission in PARK. Make sure that all unused vacuum outlets
are correctly capped, hose connectors are correctly secured and vacuum hoses are in good condition. When it is
established that manifold vacuum is available to the brake booster, connect the vacuum hose to the brake booster and
repeat Step 3. If no downward movement of the brake pedal is felt, install a new brake booster.

5. Operate the engine for a minimum of 10 seconds at a fast idle. Stop the engine and allow the vehicle to stand for 10
minutes. Then, apply the brake pedal with approximately 89 N (20lb) of force. The pedal feel (brake application) should
be the same as that noted with the engine running. If the brake pedal feels hard (no power assist), install a new valve
and then repeat the test. If the brake pedal still feels hard, install a new brake booster. If the brake pedal movement
feels spongy, bleed the brake system.
REFER to: Brake System Bleeding (206-00 Brake System - General Information, General Procedures). Brake Master Cylinder

Usually, the first and strongest indicator of anything wrong in the brake system is a feeling through the brake pedal. In
diagnosing the condition of the brake master cylinder, check pedal feel as evidence of a brake concern. Check for brake warning
lamp illumination and the brake fluid level in the brake master cylinder reservoir.
Normal Conditions
The following conditions are considered normal and are not indications that the brake master cylinder is in need of repair.

Modern brake systems are designed to produce a pedal effort that is not as hard as in the past. Complaints of light
pedal efforts should be compared to the pedal efforts of another vehicle of the same model and year.
The fluid level will fall with brake pad wear.

Abnormal Conditions

Changes in the brake pedal feel or brake pedal travel are indicators that something could be wrong in the brake system. The
diagnostic procedure and techniques use brake pedal feel, warning indicator illumination and low brake fluid level as indicators
to diagnosing brake system concerns. The following conditions are considered abnormal and indicate that the brake master
cylinder is in need of repair:

NOTE: Prior to carrying out any diagnosis, make sure the brake system warning indicator is functional.
Brake pedal goes down fast. This could be caused by an external or internal leak.
Brake pedal goes down slowly. This could be caused by an internal or external leak.
Brake pedal is low or feels spongy. This condition may be caused by no fluid in the brake master cylinder, reservoir cap
vent holes clogged or air in the hydraulic system.
Brake pedal effort is excessive. This may be caused by a bind or obstruction in the pedal/linkage, a faulty non-return
valve, booster or insufficient booster vacuum.
Rear brakes lock up during light pedal force. This may be caused by damaged brake pads, a partially applied parking
brake, a damaged ABS sensor or bearing failure.
Brake pedal effort erratic. This condition could be caused by the brake booster or incorrectly installed brake pads.
Brake warning indicator is on. This may be caused by low fluid level or float assembly damaged. www.JagDocs.com
