TEST ACTION APPLICABILITY
1NOTE: Inspect the ASD Relay fuse located in the IPM. If the ASD Relay fuse
is open, repair the cause of the open first before continuing. Inspect the ASD
Relay Output circuit for a short to ground for the cause of the open fuse.
NOTE: Diagnose P1388 - Auto Shutdown Relay Control Circuit first if set
along with this DTC.
With the DRBIIIt, erase the DTC.
Attempt to start the engine. If the engine will not start, crank the engine for at least
15 seconds. It may be necessary to repeat several times.

9WARNING: WHEN THE ENGINE IS OPERATING, DO NOT STAND IN A
DIRECT LINE WITH THE FAN. DO NOT PUT YOUR HANDS NEAR THE
PULLEYS, BELTS OR FAN. DO NOT WEAR LOOSE CLOTHING.
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 DRB
parameters related to the DTC while wiggling the wiring harness. Check for the
engine stumble, stall or quite running.
Refer to any Technical Service Bulletins (TSB) that may apply.
Visually inspect the related wiring harness. Look for any chafed, pierced, pinched, or
partially broken wires.
Visually inspect the related wiring harness connectors. Look for broken, bent, pushed
out, or corroded terminals.
