Diagnostic Trouble Code Priority Index

The faults and associated codes are listed in the Fault Code Priorities chart in the order that they are ranked from top to bottom. In other words, the fault (or code) at the top of the list has the highest priority (or ranking) and would be shown over any other code by the air bag indicator.

The fault (or code) at the bottom of the list has the lowest priority (or ranking). These listings are for information only and should not be used for system diagnosis or troubleshooting. The following diagnostic charts and deactivation procedure should be used to pinpoint the specific fault and to safely diagnose and service the system. However, if after using the diagnostic charts, the fault is not located, proceed to the diagnostic schematic to perform additional diagnostic checks to determine and correct uncommon faults.
