Schematic for the air shutoff system
Table 1
Troubleshooting Test Steps Values Results
1. Inspect the Electrical Connectors and the Wiring
A. Remove electrical power from the ECM.
B. Verify that the air shutoff mechanisms are set to the OPEN position.
C. Thoroughly inspect the connectors. Also, inspect the connections at the air shutoff solenoid. Refer to Troubleshooting, "Electrical Connectors - Inspect" for more information.
D. Perform a 45 N (10 lb) pull test on each of the wires that are associated with the circuit for the air shutoff system. Perform a 45 N (10 lb) pull test on each of the wires that are associated with the circuit for the air shutoff system.
E. Check the allen head screw on each ECM connector for the proper torque. Also, check the allen head screw on the customer connector for the proper torque. Refer to Troubleshooting, "Electrical Connectors - Inspect" for the correct torque values.
F. Check the harness and the wiring for abrasion and for pinch points from the air shutoff solenoid to the ECM.
