3)

Is the measured resistance within specification?

YES

▶ Substitute with a known - good PCM and check for proper operation. If the problem is corrected, replace PCM
and go to "Verification of Vehicle Repair" procedure.

NO

▶ Substitute with a known - good VIS #2 and check for proper operation. If the problem is corrected, replace
VIS #2 and go to "Verification of Vehicle Repair" procedure.

NOTE

There is a memory reset function on scantool that can erase optional parts automatically detected and memorized
by PCM. After testing PCM on the vehicle, use this function to reuse the PCM on the others

DTC P0685 ECM/PCM POWER RELAY CONTROL CIRCUIT /OPEN

COMPONENT LOCATION

E032C31A

Main Relay

Fuel Pump Relay

SCMF16254L

GENERAL DESCRIPTION

E8B88C29

The ECM provides ground to one side of the coil of the main relay and the other side is connected to the battery. The
ECM monitors battery voltage and the voltage after the main relay.

DTC DESCRIPTION

E931EEBC

Checking the contolling state of main relay every 10 sec. under detecting condition, if open or short in the circuit is
detected for more than 5 sec., PCM sets P0685.

DTC DETECTING CONDITION

ED8CA705

Item

Detecting Condition

Possible cause

DTC Strategy

• Detects a short to ground, to battery or open

circuit on Main Relay output Fault information
provided by an output driver chip.

EnableConditions

• Engine Running
• 11V ≤ Ignition Voltage ≤ 16V
• Enable Time delay ≥ 0.5sec.

Threshold value

• Open or Short

DiagnosisTime

• Contineous

(More than 5sec. Failure for every 10 sec. test)

MIL On Condition

• DTC only (NO MIL ON)

• Poor Connection
• Open or short in control

circuit.

• Main Relay
• PCM
