TSB : Checking Components And Wiring

Details

Fig 1: Identifying Ignition OFF Courtesy of VOLVO CARS OF NORTH AMERICA. Ignition off. Check the resistance of the solenoids. Check the connectors for the Suspension Module (SUM) and the solenoids. Check for oxidation. For diagnostic trouble code (DTC) SUM-0117, front left solenoid: Check the signal cable between control module #A7 and solenoid terminal #2. Check for a short-circuit to supply voltage. For diagnostic trouble code (DTC) SUM-0127, front right solenoid: Check the signal cable between control module terminal #A8 and solenoid terminal #2. Check for a short-circuit to supply voltage or to the power supply cable for the solenoid. For diagnostic trouble code (DTC) SUM-0137, rear left solenoid: Check the signal cable between control module terminal #A1 and solenoid terminal #2. Check for a short-circuit to supply voltage or to the power supply cable for the solenoid. For diagnostic trouble code (DTC) SUM-0147, rear right solenoid: Check the signal cable between control module terminal #A4 and solenoid terminal #2. Check for a short-circuit to supply voltage or to the power supply cable for the solenoid. HINT: Click on the VCT2000 symbol to activate the power supply to the solenoids. This will make fault-tracing easier. Measure the current on the signal cable. The value must be approximately 0.5 A. Remedy as necessary.
