DTC 2

Circuit Description
The A, B, C, and D are the actuator motor coil terminals. DC 12V driving voltage is applied between terminals A and C and terminals B and D so that the shock absorber oil valves are rotated at every 7.5° step feed.

Diagnostic Aids
^ Inspect the wiring for poor electrical connections between the control unit 24 way connector and the actuator connectors. Look for possible bent, backed out, deformed, or damaged terminals. Check for weak terminal tension as well.
Also check for a chafed wire that could short to bare metal or other wiring. Inspect for a broken wire inside the insulation.
^ When diagnosing for a possible intermittent short or open condition, move the wiring harness while observing test equipment for a change.
