Fixes for Dodge Caravan 2008 - 2010 (RT)



Vehicle:  2008 (RT) Dodge Caravan and Chrysler Town & Country with power sliding doors

Concern:  Power sliding doors will not close at times; they close partially, then reverse to the full open position. Condition may be intermittent.

Cause:  Software error.

Resolution:  Have the dealer reprogram (flash) both power sliding door modules. If the modules are already at the latest software version, or the flash does not correct the problem, further diagnosis may be required.

Details:  -

[EDIT]


Vehicle:  All vehicles. (JK)(ZJ)(CS)(JC)(TJ)(XJ)(PT)(KJ)(KK)(KA)(AN)(ND)(DR)(DS)(WJ)(WK)(XK)(LX)(LH)(FJ)(JR)(JS)(RT)(RS)(NS)

Concern:  The MIL (check engine light) is on. The scan tool reveals DTC P0601 PCM internal controller failure.

Cause:  The PCM (engine computer) has an internal fault.

Resolution:  Replace the PCM to correct.

Details:  This is an easy diagnosis. When P0601 is present, the solution is always to replace the PCM. There is no other possible cause. Normally the vehicle is still driveable.

[EDIT]


Vehicle:  All Chrysler, Jeep, and Dodge vehicles. (JK)(ZJ)(CS)(JC)(TJ)(XJ)(PT)(KJ)(KK)(KA)(AN)(ND)(DR)(DS)(WJ)(WK)(XK)(LX)(LH)(FJ)(JR)(JS)(RT)(RS)(NS)

Concern:  Alternator failure. The alternator (generator) is not charging. Electrical problems.

Cause:  -

Resolution:  Hold on for a minute. Alternator failures are extremely rare on Chrysler, Jeep, and Dodge. You need to rule out the battery, wiring, and PCM first before replacing the alternator.

Details:  The alternator is controlled by the PCM (engine computer). Again, true alternator failure is very rare. In ten years as a dealer service dept tech, I have replaced maybe five alternators.
