2000 CHRYSLER CARAVAN key battery

3.3.2 Intermittent Code
A diagnostic trouble code that is not there every time the engine control module/SKIM checks the
circuit is an ªintermittentº code. Most intermittent codes are caused by wiring or connector
problems. Defects that come and go like this are the most difficult to diagnose; they must be
looked for under specific conditions that cause them. The following checks may assist you in
identifying a possible intermittent problem:
²Visually inspect related wire harness connectors. Look for broken, bent, pushed out, or
corroded terminals.
²Visually inspect the related harnesses. Look for chafed, pierced, or partially broken wire.
²Refer to any hotlines or technical service bulletins that may apply.
NOTE: Electromagnetic (radio) interference can cause an intermittent system malfunction. This
interference can interrupt communication between the ignition key transponder and the SKIM.
3.3.3 Reset Counter
The reset counter counts the number of times the vehicle has been started since codes were last
set, erased, or the battery was disconnected. The reset counter will count up to 255 start counts.
The number of starts helps determine when the trouble code actually happened. This is recorded
by the ECM and can be viewed on the DRB as the RESET COUNTER.
When there are no trouble codes stored in memory, the DRB will display ªNO TROUBLE CODES
FOUNDº and the reset counter will show ªRESET COUNT = XXX.º

TEST SK-1AIDENTIFYING SENTRY KEY IMMOBILIZER SYSTEM PROBLEMS
NOTE:The Sentry Key Immobilizer System (SKIS) diagnosis may require usage of the customer's
additional keys to verify the cause of the system failure. In the event that the Sentry Key Immobilizer
Module (SKIM) needs replacing, all of the keys previously programmed into the SKIM's memory
must be programmed into the new SKIM.THEREFORE IT IS IMPORTANT THAT ALL OF THE
CUSTOMER'S KEYS PROGRAMMED FOR THE VEHICLE BE OBTAINED PRIOR TO BEGIN-
NING VEHICLE DIAGNOSIS.
NOTE:It is necessary to obtain the four-digit Personal Identification Number (PIN) from the
customer or the vehicle invoice. The PIN is required to perform certain SKIM tasks using the DRB.
NOTE:It is very important that the ECM/BCM is programmed with the correct Vehicle Identification
Number (VIN). Incorrect VIN programming may result in incorrect diagnosis and unnecessary
component replacement. Use the DRB to verify the correct VIN and country code are programmed
into the SKIM.
1. The battery must be fully charged for any test in this manual.
2. Attempt to start the engine. Crank for up to 10 seconds if necessary.
3. Connect the DRB to the diagnostic connector and select ``Theft Alarm'' then ``SKIM''.
If the DRB displays ``No Response''..................................perform test 1B
NOTE:If the DRB screen is blank or has a DRB error message displayed, go toGeneral
Information Section 3.5in this manual.
4. With the DRB, read and record SKIM trouble codes.
5. If diagnostic trouble code are displayed, refer to the diagnostic trouble code list on the next page
for the appropriate test.
NOTE:For all component locations, seeGeneral Information Section 4.0in this manual.

**These trouble codes indicate an internal SKIM fault. Using the DRB, clear SKIM trouble code(s).
Perform several key cycles, leaving the key on for a minimum of 30 seconds per cycle. Using the
DRB, read SKIM trouble codes. If the trouble code is present, replace the SKIM.
NOTE:An intermittent start and stall condition accompanied with a transponder DTC can be caused
by the presence of a non-programmed key or key programmed to another vehicle, near the SKIM
antenna (ignition halo). This can occur if the customer has a key holder (ring) that contains more
than one key equipped with a transponder chip.
After replacement of the Sentry Key Immobilizer Module (SKIM) seeGeneral Information Section 8.0
for SKIM initialization.

TEST NS-SELNO START SELECTION MENU
NOTE:The battery must be fully charged before performing any test in this manual.
NOTE:If the engine will not crank or cranks but will not run, be sure to check the Sentry Key
Immobilizer Module (SKIM) for proper communication and trouble codes.
NOTE:With the DRB, attempt to read ECM trouble codes. If the DRB is unable to communicate with
the ECM, perform test NS-2A. If there are any trouble codes present they must be repaired before
continuing with the No Start Symptom diagnostics.
Below you will find a recommended procedure to correct a No Start Problem by symptom. They
should be performed in the order that they are listed.
Repairing a No Crank Condition..............................................NS-1A
Repairing a No Response Condition...........................................NS-2A
Repairing a No Start Condition................................................NS-3A
Repairing a Start and Stall Condition...........................................NS-4A
Checking the Engine Mechanical Systems......................................NS-5A
NOTE:A failed engine coolant temperature (ECT) sensor can cause a cranks but will not run or an
extended cranking before starting condition. This occurs when the ECT sensor calibration fails
(sensor indicates engine temp is warmer than actual engine temp) and the ECM cannot command
proper fuel quantity to the injection pump.
NOTE:For all component locations seeGeneral Information Section 4.0 in this manual.
