Condition

The control module has discovered a malfunction during the self-check.

Diagnostic procedure

Checking wiring harness

Intermittent faults can exist during temporary short circuits and open circuits. Wiggle the wiring harness at several points and in different directions to discover problems in the wiring harness and connectors. Observe the multimeter, diagnostic tool or the test lamp during checking.
