Scan Tool Testing and Procedures

CAUTION: When checking resistance in the RABS II system, always disconnect the battery ground cable. Improper resistance readings may occur with the vehicle battery connected.

NOTE: Refer to Obtaining the Diagnostic Trouble Code in this section for procedure to obtain flashout code. [1][2]Displaying and Reading Trouble Codes

For easier access to the RABS II valve connector, construct a jumper harness with a 4-pin connector F07Z-14A464-B and four sections of 18-inch long wire. The wire sections should be of different colors or labeled for quick reference.
