OK -- CHECK HARNESS AND CONNECTOR (DLC3 - SUSPENSION CONTROL ECU)

NG -- Continue to next step.

2. CHECK HARNESS AND CONNECTOR (DLC3 - BODY GROUND)
(a) Check for open and short circuit in the harness and the connector between terminal CG of DLC3 and body ground Electronic Circuit Inspection Procedure.

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.

3. CHECK HARNESS AND CONNECTOR (DLC3 - SUSPENSION CONTROL ECU)
(a) Check for open and short circuit in the harness and the connector between terminal TS of DLC3 and the suspension control ECU Electronic Circuit Inspection Procedure.
