DTCs P0201, P0202, P0204, P0443, P0449, P1691, P1693 with an Extended Cranking Time and/or Start then Stall #98-T-02 - (Jan 2, 2003)
DTCs P0201, P0202, P0203, P0204, P0443, P0449, P1691, P1693 with an Extended
Cranking Time and/or Start then Stall -- Replace the Ignition Start Switch1998 Saturns built up to and including VIN WZ174921
Condition:
Vehicle may have an extended cranking time and/or start then stall during cold
ambient temperatures. Diagnostic trouble codes DTCs P0201, P0202, P0203, P0204, P0443,
P0449, P1691, P1693 may set while the engine is being started. The condition is more
likely to occur as the ambient temperature drops below 0°C (32°F).
Cause:
Ignition voltage on circuit 3C, from the ignition and start switch, may
drop out momentarily when the engine is first started. Loss of voltage on this circuit
for a certain duration will cause the above DTCs to be recorded in the PCM malfunction
history. When the PCM detects a loss of voltage during start-up, the proper fuel delivery
cannot be maintained, which could lead to the conditions mentioned.
Correction:
Refer to the malfunction history records to verify that the DTCs were stored
during engine start-up. If DTCs were caused by the ignition and start switch dropout,
the Eng. On Time will generally be less than 2 seconds. If verified, refer
to the following procedure in this bulletin to replace the ignition and start switch.
If the Eng. On Time is greater than 2 seconds, refer to the 1998 Powertrain
Controls Service Manual for diagnostic procedures.
If the vehicle condition is not related to the condition described in this bulletin
and/or if additional DTCs have set, they must also be diagnosed and repaired before
returning the vehicle to the customer. Refer to the appropriate service manual for
diagnostic procedures.
Procedure:
Caution
When you are performing service on or near the SIR components or the SIR wiring,
you must disable the SIR System. Use the following procedure to temporarily disable
the SIR System. Failure to follow the correct procedure could cause air bag deployment,
personal injury, or unnecessary SIR System repairs.
Caution
The inflatable restraint sensing and diagnostic module maintains a reserve energy
supply. When the vehicle power is insufficient to cause deployment of the air bags,
the reserve energy supply provides the deployment power. Deployment power is available
for as much as 10 minutes after disconnecting the vehicle power by any of the
following methods:
- You turn OFF the ignition switch.
- You remove the fuse that provides power to the inflatable restraint sensing
and diagnostic module.
- You disconnect the vehicle battery from the vehicle electrical system.
Performing the following procedures prevents deploying of the air bags from
the reserve energy supply power.
- Turn the steering wheel so that the vehicle's wheels are pointing straight
ahead.
- Turn the ignition key to the lock position and remove the key.
- Remove the AIR BAG fuse from the I/P junction
block.
Important
With the AIR BAG fuse removed and the ignition switch ON, the AIR BAG warning
lamp will be ON. This is normal operation and does not indicate a SIR system malfunction.

provide information that could assist in the proper service of a
vehicle. Properly trained technicians have the equipment,
tools, safety instructions, and know-how to do a job properly and

bulletin applies to your vehicle, or that your vehicle will have
that condition. See your GM dealer for information on whether
your vehicle may benefit from the information.
