DTC 3
DTC 3: ACTUATOR COIL/POSITION SENSOR OPEN CIRCUIT OR SHORTCircuit Description
The A, B, C, and D are the actuator motor coil terminals. DC 12 V 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.
The PSW is actuator position signal and detects relative angles between the piston-rod and the control-rod. The actuator outputs the PSW to the control unit.
Diagnostic Aids
- Inspect the wiring for poor electrical connections between the control unit 16-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.
