C3 Damaged Module Ground

Pinpoint Test Diagram:

- Disconnect the battery ground cable (14301).

- Set the multimeter on the 200-ohm scale.

- Shake the anti-lock electronic control module harness while reading the resistance between Pin 4 and chassis ground.

- Is resistance steady and less than 1 ohm?

YES -- Replace anti-lock electronic control module. Reconnect the battery ground cable. Repeat System Pre-Check. [1][2]C - Test system pre check

NO -- Repair poor ground in circuit 530 (BK/W). Reconnect the battery ground cable. Repeat system pre-check. [1][2]C - Test system pre check
