DIAGNOSTIC TROUBLE CODE (DTC) – P0336 58X CRANKSHAFT POSITION
SENSOR NO PLAUSIBLE SIGNAL
Circuit Description
The 58X reference signal is produced by the crankshaft
position (CKP) sensor. During one crankshaft revolu-
tion, 58 crankshaft pulses will be produced. The engine
control module(ECM) uses the 58X reference signal to
calculate engine rpm and CKP. The ECM constantly
monitors the number of pulses on the 58X reference cir-
cuit and compares them to the number of camshaft posi-
tion (CKP) signal pulses being received. If the ECM
receive and incorrect number of pulses on the 58X refer-
ence circuit, DTC P0336 will set.
Conditions for Setting the DTC
This DTC can be stored in “key-on” status.
Detected number of teeth is differs by 3 or higher.
Action Taken When the DTC Sets
The Malfunction Indicator Lamp (MIL) will illuminate.
The ECM will record operating conditions at the time
the diagnostic fails. This information will be stored in
the Freeze Frame and Failure Records buffers.
A history DTC is stored.
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.
DTC(s) can be cleared by using the scan tool.
Disconnecting the ECM battery feed for more than 10
seconds.
DIAGNOSTIC AIDS
An intermittent may be caused by a poor connection,
rubbed-through wire insulation or a wire broken inside
the insulation. Check for :
Poor connection – inspect the ECM harness and con-
nectors for improper mating, broken locks, improperly
formed or damaged terminals, and poor terminal-to-wire
connection.
Damaged harness – inspect the wiring harness for dam-
age. If the harness appears to be OK, disconnect the
ECM, turn the ignition ON and observe a voltmeter con-
nected to the 58X reference circuit at the ECM harness
connector while moving the connectors and the wiring
harness related to the ECM. A change in voltage will in-
dicate the location of the fault.
Review the failure records vehicle mileage since the
diagnostic test failed may help determine how often the
condition that caused the DTC to be set occurs. This
may assist in diagnosing the condition.
9T–2 REMOTE KEYLESS ENTRY AND ANTI-THEFT SYSTEM
DAEWOO M-150 BL2
DESCRIPTION AND OPERATION
REMOTE KEYLESS ENTRY AND
ANTI-THEFT SYSTEM
The remote keyless entry and anti-theft system can per-
form the following functions:
Remotely lock and unlock the vehicle doors with a
hand-held high-frequency transmitter.
Sense intrusion into the vehicle through the doors,
the tailgate, or the hood.
Activate a warning to signal an intrusion.
Help the driver find the vehicle in a parking area.
Automatically re-lock the doors if a door or the trunk is
not opened within 30 seconds after the vehicle has
been unlocked by the remote keyless entry.
Communicate serial data to a scan tool to help diag-
nose system faults.
The remote keyless entry and anti-theft system consists
of the following components:
Keyless entry and anti-theft control module/receiver.
Security indicator.
Tailgate open switch.
Door open switches.
Central locking unit.
Flashing turn signal lamps.
Siren.
Hood open switch.
REMOTE LOCKING AND UNLOCKING
The hand-held transmitter locks and unlocks the vehicle
doors by sending radio waves to the control module/re-
ceiver in the vehicle. The effective range of the transmit-
ter varies between 5 and 10 meters (approximately 16 to
32 feet), depending on whether or not objects such as
other vehicles are blocking the path of the radio waves.
The transmitter has a LOCK button and an UNLOCK
button which only function when the ignition is OFF.
Pressing the UNLOCK button has the following effects:
The doors are unlocked.
The turn signal lamps flash twice.
The control module is disarmed.
Pressing the LOCK button has the following effects:
The doors are locked.
The turn signal lamps flash once.
The control module is armed.
The transmitter has a replaceable battery. The battery is
designed to last at least two years before replacement is
necessary.
SECURITY INDICATOR
There is a security indicator on the instrument panel. Af-
ter the LOCK button of the transmitter is pressed, the
module is placed in the armed mode, and the security
indicator flashes. The security indicator turns ON for 1/8
second and OFF for 7/8 second. It then flashes at that
frequency until the control module/receiver is disarmed.
INTRUSION SENSING
The anti-theft function is armed if the transmitter sends
the LOCK message to the control module/receiver when
the ignition is OFF.
When the hood, the door, or the tailgate is opened, the
hood open switch, the door open switch, or the tailgate
open switch will change its input to ground. The alarm
will be activated if the hood open sensor, the door open
sensor, or the tailgate open sensor changes its input to
ground before either of the following conditions occurs:
An UNLOCK message is received from the transmit-
ter.
SIREN
The remote keyless entry system is armed when the
LOCK message is received from the transmitter when
the ignition is OFF. When the system is armed, it will ac-
tivate the siren and flash the turn signals for 28 seconds
if any of the following conditions occurs:
A door is opened (front door open switch input is
changed to ground).
The tailgate is opened (tailgate open switch input is
changed to ground).
The hood is opened while the anti-theft system is
armed (hood open switch input is changed to
ground).
The siren is disarmed when any of the following condi-
tions occurs:
The ignition switch is turned ON with the key.
The UNLOCK button or the LOCK button on the re-
mote transmitter is pressed.
VEHICLE LOCATOR
The remote keyless entry system assists the driver in lo-
cating the vehicle. When the vehicle is unlocked with the
remote control, the turn signals flash twice to indicate
the location of the vehicle. The duration of the flashes
and the length of time between flashes is used to indi-
cate certain vehicle conditions. Refer to “Fault or Alarm
Indication” in this section.
