TROUBLE SHOOTING
ROAD TEST
Perform a road test to verify speed control malfunctions.
Ensure speedometer operation is smooth without flutter at all speeds.
Speedometer fluttering may cause surging in speed control system. For
speedometer diagnosis, see appropriate INSTRUMENT PANELS article. If
road test verifies a surge following speed control set and speedometer
operates smoothly, see OVERSHOOT/UNDERSHOOT FOLLOWING SPEED CONTROL
SET.
If road test verifies an inoperative system, and speedometer
operates smoothly, check for:
* Diagnostic Trouble Codes (DTCs). See SELF-DIAGNOSTIC
SYSTEM.
* Misadjusted brake switch. See BRAKE SWITCH under REMOVAL &
INSTALLATION.
* Poor electrical connections at servo.
* Leaking vacuum reservoir, check valve, hoses or connections.
See VACUUM SUPPLY under COMPONENT TESTS.
* Secure attachments of S/C servo cable.
* Smooth operation of throttle linkage.
* Defective PCM or wiring.
* Defective servo. See SPEED CONTROL SERVO under COMPONENT
TESTS.
To verify a speed control electronic malfunction, use scan
tool to check for DTCs. See SELF-DIAGNOSTIC SYSTEM. A speed control
malfunction may occur without setting a FTC. If no DTCs are stored, go
to CHECKING SPEED CONTROL OPERATION under SYSTEM TESTS.
OVERSHOOT/UNDERSHOOT FOLLOWING SPEED CONTROL SET
If operator repeatedly presses and releases set button with
their foot off accelerator (lift foot set) to begin speed control
operation, vehicle may accelerate and exceed desired set speed by 5
MPH and then decelerate to less than desired set speed before
achieving desired set speed.
Speed Control (S/C) has as adaptive strategy that compensates\
for variations in S/C cable lengths. When S/C is set with vehicle
Page 389 of 1691
made.
* When using a jumper wire, ensure either jumper wire or
circuit is fuse-protected.
* Before disconnecting connector from any control module,
ensure ignition is off before removing connector.
* When checking voltage or continuity at any control module,
probe connector for control module from pin side. DO NOT
backprobe connector or probe wires through insulation.
* DO NOT cause short circuits when performing electrical tests.
This will set additional Diagnostic Trouble Codes (DTCs),
making diagnosis of original problem more difficult.
* Use specified test equipment when performing electrical
tests.
RETRIEVING DIAGNOSTIC TROUBLE CODES
NOTE: Self-diagnostic tests are written specifically for Chrysler's
Diagnostic Readout Box (DRB). If using a generic scan tool,
ensure it is OBD-II certified. A generic scan tool may not be
capable of performing all necessary test functions.
Ensure battery is fully charged. Turn ignition off. Connect
scan tool to Data Link Connector (DLC). DLC is located under left side\
of instrument panel. Turn ignition on. Using scan tool manufacturer's
instructions, record all DTCs displayed on scan tool. If ant DTCs are
retrieved, perform appropriate test under DIAGNOSTIC TESTS. Once all
repairs are made, clear DTCs. See CLEARING DIAGNOSTIC TROUBLE CODES.
If no DTCs are retrieved and fault still exists, go to CHECKING SPEED
CONTROL OPERATION under SYSTEM TESTS.
CLEARING DIAGNOSTIC TROUBLE CODES
Ensure ignition is off. Connect scan tool to DLC. Turn
ignition on. Using screen prompts on scan tool, erase DTCs from PCM.
DIAGNOSTIC TESTS
FTC P0720: LOW OUTPUT SPEED SENSOR (OSS) RPM MORE THAN 15 MPH
FTC P0720 will set if output shaft speed is less than 60 RPM
for 2.6 seconds when vehicle speed is more than 15 MPH.
Possible Causes:
* Defective Output Speed Sensor (OSS).
* OSS signal circuit open or shorted.
* OSS ground circuit open or shorted.
* Park/Neutral Position (PNP) switch FTC present.
* Defective PNP switch.
* Defective PCM.
1) Turn ignition on. Using scan tool, read DTCs. If FTC
specific good trip is displayed and equal to zero, go to next step. If
FTC specific good trip is equal to more than zero, go to step 13).
2) If there are any Park/Neutral Position (PNP) switch DTCs,\
repair PNP switch FTC first. Perform TEST VER-5A under VERIFICATION
TESTS. If there are no PNP switch DTCs, go to next step.
3) Using scan tool, read PNP switch state. While observing
scan tool, shift transmission through all positions. If scan tool did
not display P/N and D/R in correct positions, repair PNP switch or
circuit as necessary. Perform TEST VER-5A under VERIFICATION TESTS. If
Page 401 of 1691
10) Depress and release CANCEL switch. If S/C disengages, go
to next step. If S/C did not disengage, repair is not complete. Check
for related TSBs and return to TROUBLE SHOOTING, if necessary.
11) Ensure vehicle speed is greater than 35 MPH. Engage speed
control. Turn S/C on/off switch to OFF position. If speed control
disengages, system is operating correctly. Repair is complete. If
speed control does not disengage, repair is not complete. Check for
related TSBs and return to TROUBLE SHOOTING, if necessary.
TEST VER-5A
NOTE: If PCM has been replaced and correct VIN and mileage have not
been programmed, a FTC will be set in ABS and air bag
modules. If vehicle is equipped with a Sentry Key Immobilizer
Module (SKIM), sentry key data must be updated to enable
starting. See COMPUTER RELEARN PROCEDURES article in GENERAL
INFORMATION.
1) If vehicle is not equipped with a diesel engine, go to
next step. If vehicle is equipped with a diesel engine, and PCM has
been disconnected or replaced, battery has been disconnected, or
Accelerator Pedal Position Sensor (APPS) has been disconnected or
replaced, APPS calibration must be programmed into PCM (diesel only).
Turn ignition on. Slowly press accelerator pedal to floor and slowly
release. DO NOT attempt to adjust screws or disassemble APPS. Go to
next step.
2) On all engines, if vehicle is equipped with ABS or air
bag, enter correct VIN and mileage in PCM. Erase DTCs in ABS and air
bag modules. Inspect vehicle to ensure all engine and speed control
system components are connected.
3) If there are any DTCs that have not been repaired, go to
SELF-DIAGNOSTIC SYSTEM. After all DTCs have been repaired, run
appropriate monitor for previously repaired FTC.
4) Connect scan tool to DLC. Ensure fuel tank is at least 1/4
full. Turn off all accessories. Allow PCM to run appropriate monitor
and increment appropriate good trip. Enabling conditions must be met
before monitor will run.
5) Using scan tool, monitor pretest enabling conditions until
all conditions have been met. Once enabling conditions have been met,
monitor appropriate monitor.
6) If repaired FTC has reset or was seen in monitor while on
road test, repair is not complete. Check for TSBs or flash updates and
return to TROUBLE SHOOTING.
7) If appropriate monitor ran, good trip counter incremented
and no DTCs have been set, repair is complete.
REMOVAL & INSTALLATION
WARNING: Vehicle is equipped with an air bag. Air bag must be
deactivated before servicing speed control components on or
around steering column. See AIR BAG RESTRAINT SYSTEMS -
TRUCKS article.
CAUTION: When battery is disconnected, vehicle computer and memory
systems may lose memory data. Driveability problems may exist
until computer systems have completed a relearn cycle. See
COMPUTER RELEARN PROCEDURES article in GENERAL INFORMATION
before disconnecting battery.
