DIAGNOSTIC TROUBLE CODE (DTC) – P1611 MAIN RELAY LOW VOLTAGE
Circuit Description
When the ignition switch to ON, main relay will grounded
to ECM internal ground by ECM controlling.
A system voltage Diagnostic Trouble Code (DTC) will
set whenever the voltage is below a calibrated value.
Conditions for Setting the DTC

This DTC can be stored in “key-on” status.

Main relay wiring harness high voltage.
Action Taken When The DTCs Sets

The ECM will illuminate the Malfunction Indicator
Lamp (MIL).

A history DTC is stored.

The ECM will record operating conditions at the time
the diagnostic fails. This information will be stored
Failure Records buffers.
Conditions for Clearing the MIL/DTC

The MIL will turn off after four consecutive ignition
cycles in which the diagnostic runs without a fault.
A history DTC will clear after 40 consecutive warm up
cycles without a fault.

Using the scan tool can clear DTC(s).
Diagnostic Aids
Inspect harness connectors for backed-out terminals,
improper mating, broken locks, improperly formed or
damaged terminals, and poor terminal-to-wire connec-
tion at the ECM.
Inspect the wiring harness for damage. If the harness
appears to be OK, observe the A/C pressure display on
the scan tool while moving the connectors and wiring
harnesses related to the ACP sensor. A change in the
A/C pressure display will indicate the location of the
fault.
If DTC P1611 cannot be duplicated, reviewing the Fail
Records vehicle mileage since the diagnostic test last
failed may help determine how often the condition that
caused the DTC to set occurs. This may assist in diag-
nosing the condition.
