TEST
7 Turn the ignition off.
Disconnect the MTV Solenoid harness connector.
Remove the ASD Relay from the PDC.
Measure the resistance of the ASD Relay Output circuit between the ASD Relay
connector and the MTV Solenoid harness connector.
Is the resistance below 5.0 ohms?
Yes → Go To 8
→ Repair the open in the ASD Relay Output circuit.
No
8 NOTE: Repeat the following test for both capacitors
NOTE: The Capacitors are attached to the side of each valve cover.
Turn the ignition off.
Disconnect the Capacitor harness connector.
Install a good INJ/COIL fuse.
With the DRBIII , actuate the ASD Relay.
NOTE: If the above test result is an open fuse for both capacitor tests, the
problem is a short to ground in the ASD Relay Output circuit. Repair the
short to ground in the ASD Relay Output circuit and refer to VER-5.
Is the INJ/COIL fuse OK for both capacitor tests?
Yes → Replace the Capacitor(s)
→ Repair the ASD Output circuit for a short to ground.
No
9 NOTE: The conditions that set the DTC are not present at this time. The
following list may help in identifying the intermittent condition.

With the engine running at normal operating temperature, monitor the DRBIII
parameters related to the DTC while wiggling the wire harness. Look for parameter
values to change and/or a DTC to set.
Review the DRBIII Freeze Frame information. If possible, try to duplicate the
conditions under which the DTC was set.
Refer to any Technical Service Bulletins (TSB) that may apply.
Visually inspect the related wire harness. Look for any chafed, pierced, pinched, or
partially broken wires.
Visually inspect the related wire harness connectors. Look for broken, bent, pushed
out, or corroded terminals.
Were any of the above conditions present?
Yes → Repair as necessary
→ Test Complete.
