DTC 16

CIRCUIT DESCRIPTION:
Refer to DTC 14 (Part 1 of 5).

FAILURE CONDITION:
DTC 16 can be set only before DTC 14 has been set. This test detects an open in the ABS enable relay coil circuit. An open in this circuit will not allow the relay to be energized thus preventing voltage/current to the motors and solenoids. If this malfunction is present and the ignition switch is turned to "LOCK" before 5 km/h (3 mph) is reached, DTC 14 is set alone.

ACTION TAKEN:
DTCs 14 and 16 are stored, ABS is disabled and the "ABS" warning light is turned on or will flash. If the rear piston is not in the home position, the red "BRAKE" warning light will also be illuminated.

TEST DESCRIPTION:
Number(s) below refer to circled Number(s) on the diagnostic chart.
1. This step indicates if the EBCM is capable of controlling the ABS enable relay as commanded.
2. This step ensures that there is continuity through the pull-in coil of the relay.
3. This step checks to ensure that voltage is available to the pull-in coil of the relay.
4. This step checks continuity in CKT "B/BI".
5. This step ensures DTC was not set due to a poor connection.

DIAGNOSTIC AIDS:
Refer to DTC 14 (Part 1 of 5).
