Test B: ABS Lamp Does Not Function (Part 2 Of 2).:

"Antilock" Indicator Lamp Does Not Function:

CIRCUIT OPERATION
When the ignition switch is first turned to "RUN" the EBCM/EBTCM goes through a self-test lasting 2-4 seconds. During this test, the EBCM/EBTCM grounds terminal 52, causing the amber "ANTILOCK" indicator to light. This serves as an indicator bulb test. The EBCM/EBTCM also grounds terminal 34, energizing the main relay. This removes the indicator ground path provided through the antilock diode and the main relay contacts.
When the self-test is completed (and no faults detected) the EBCM/EBTCM removes the ground at terminal 52, turning off the indicator. The main relay remains energized.
When the EBCM/EBTCM detects a fault, it grounds terminal 52 causing the amber "ANTILOCK" indicator to light. (Note: The EBCM/EBTCM also de-energizes the main relay creating a redundant ground path.)
When the EBCM/EBTCM is disabled for any reason (i.e. open Fuse 5B), the main relay is de-energized. This provides an "ANTILOCK" indicator ground path through the antilock diode and main relay contacts, and causes the indicator to light with no DTC being set.

FAILURE CONDITIONS
Possible Causes
^ Open in CKT 251, 852 or 1633.
^ Open bulb.
^ Short to voltage in CKT 852.
^ Open or shorted antilock diode.
^ Main relay fails "engaged."
^ Short to ground in CKT 1632.
