Diagnostic Trouble Code (DTC) 

P1299  ETC Forced Engine Shutdown Mode

060R100073

Circuit Description

D

The throttle position sensor circuit provides a voltage
signal relative to throttle position (blade angle). 

D

The DC motor circuit provides a voltage signal relative
to command throttle position (blade angle). 

D

This DTC detects if the system is in ETC Forced
Engine Shutdown Mode.(Fail safe Mode)

Conditions for setting the DTC

D

The ignition is “ON”.

D

ETC Forced Engine Shutdown Mode is active. (Fail
safe Mode)

Action Taken When the DTC Sets

D

The PCM will illuminate the malfunction indicator lamp
(MIL) and the reduced power lamp (RPL) the first time
the fault is detected.

D

The PCM will store condition which were present when
the DTC was set as Freeze Frame and in the Failure
Records data.

Conditions for Clearing the MIL/DTC

D

The PCM will turn the MIL “OFF” on the third
consecutive trip cycle during which the diagnostic has
been run and the fault condition is no longer present.

D

A history DTC P1299 will clear after 40 consecutive trip
cycle during which the warm up cycles have occurred
without a fault.

D

DTC P1299 can be cleared using the Tech 2 “Clear
Info” function or by disconnecting the PCM battery
feed.

Diagnostic Aids

An intermittent may be caused by the following:

D

Poor connections.

D

Misrouted harness.

D

Rubbed through wire insulation.

D

Broken wire inside the insulation.

Check for the following conditions:

D

Poor connection at PCM-Inspect harness connectors
for backed out terminals, improper mating, broken
locks, improperly formed or damaged terminals, and
poor terminal to wire connection.

D

Damaged harness-Inspect the wiring harness for
damage. If the harness appears to be OK, observe the
TP sensor 1, TP sensor 2 display on the Tech 2 while
moving connectors and wiring harnesses related to the
sensor.
A change in the display will indicate the location of
the fault. If DTC P1299 cannot be duplicated, the
information included in the Failure Records data can
be useful in determined vehicle mileage since the
DTC was last set.

If it is determining that the DTC occurs intermittently,
performing the DTC P1299 Diagnostic Chart may
isolate the cause of the fault.
