HOW TO USE THIS MANUAL–CONTINUED

PROBLEM:

You observe one of the rear wheels is locking when the service brake is applied during a hard

stop.

SOLUTION:

You must find information on brake lockup, troubleshoot as necessary, and correct the

problem.

Refer to the table of contents to determine what chapter and WP number (s) contain information on

troubleshooting. If there is not an obvious WP title in the table of contents for troubleshooting a brake

lockup condition, you may locate the information more quickly by using the subject index. After

reviewing the table of contents and/or subject index, you determine that Chapter 3, WP 0009, contains

the Troubleshooting Symptom Index, and WP 0010 contains Troubleshooting Procedures.

Go to WP 0009 first, and look through the malfunction/symptom titles. In reviewing the titles, you

discover the heading Troubleshooting Procedures, with several symptoms and a corresponding WP

number for each.

Go to WP 0010, review the WP Introduction, and then locate the desired SYMPTOM by page number as

noted from WP 0009. Look at each SYMPTOM for the one that best describes the problem you have

with the equipment. In this case, there is a specific symptom titled “Warning light does not illuminate

with ignition on.” There are two possible causes listed under MALFUNCTION for the symptom

“Warning light does not illuminate with ignition on,” the first tells you to look for blown fuses, and the

second tells you to check for a faulty warning light. Under the first CORRECTIVE ACTION you are

instructed to check for blown fuses, refer to WP 0030. Under the second CORRECTIVE ACTION you

are instructed to check for faulty warning light, and refer to WP 0033.

In this example, Field Maintenance will go to WP 0030 or WP 0033 and perform the necessary

procedures to correct the problem. If parts are needed go to WP 0038 to read the RPSTL Introduction and

“How to Locate Repair Parts” before looking for the replacment parts needed in WP 0039 through

WP 0058. After completing this task, refer to the table of contents or the subject index and find the

WP for operation of the ABS brake system. In this example, WP 0005 provides operating instructions for

the ABS brake system. Test and verify the ABS brake system is operational.
