DTC 4

Circuit Description
The G-sensor sends the voltage (Vout) corresponding to the vehicle vertical gravity to the control unit.
The control unit supplies DC 5V power (Vcc) to each G-sensor.
The control unit watches the G-sensor operation through Vcc signal.

Diagnostic Aids
Inspect the wiring for poor electrical connections between the control unit connectors 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.
