Diagnostic Monitoring Test Results

The purpose of this test mode is to allow access to the results of OBD monitor diagnostic test results. The test values that are stored at the time of the particular monitor completion are displayed when the particular test identification is requested. Refer to DIAGNOSTIC MONITORING TEST RESULTS  table for test information.

(1) = hexadecimal
(2) = These test IDs are signed values. The diagnostic tool may display them as unsigned.

The conversion is done as follows:

If the value is > 32767 then complement (change 0's to 1's and 1's to 0's), add 1 and a negative sign.

Example:

CONVERSION

50000 = 1100001101010000
Complement of 50000 = 0011110010101111
+1
  0011110010110000
Signed Value = -15536
