ID26 Air Line Check (Restriction Check)

^ From the previous tests, it has been determined that cause of the unable to inflate problem is due to a restriction in the air line or compressor assembly. In order to isolate the cause of this problem the following actions are required:

^ Disconnect any one of the air lines that are plugged into the air compressor drier assembly.

NOTE: As long as STAR test button remains in the up HOLD position the air compressor assembly will continue to pump air through the drier assembly.

^ The rate that air is coming out of the drier assembly is:

Same as in Step ID25 or slightly greater -- INSTALL a new air compressor assembly and then REPEAT Service Bay Diagnostics. Reading and Clearing Diagnostic Trouble Codes

Rate is faster than in step ID25 -- SERVICE restriction in left rear air line. REPEAT Service Bay Diagnostics. Reading and Clearing Diagnostic Trouble Codes
