VERIFICATION TESTS
TEST VER-4A
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. Reassemble and reconnect components
as necessary. Using scan tool, erase DTCs from PCM.
3) Road test vehicle at a speed greater than 35 MPH. Turn S/C
switch on. Press and release SET button. If S/C does not engage,
repair is not complete. Check for related TSBs and return to TROUBLE
SHOOTING, if necessary. If speed control engages, go to next step
4) Quickly depress and release RESUME/ACCEL switch. If
vehicle speed increases by 2 MPH, go to next step. If vehicle speed
does not increase by 2 MPH, repair is not complete. Check for related
TSBs and return to TROUBLE SHOOTING, if necessary.
5) Press and hold COAST switch. Vehicle speed should
decrease. If vehicle speed decreases, go to next step. If vehicle
speed does not decrease, repair is not complete. Check for related
TSBs and return to TROUBLE SHOOTING, if necessary.
6) Using caution, depress and release brake pedal. If S/C
disengages, go to next step. If S/C does not disengage, repair is not
complete. Check for related TSBs and return to TROUBLE SHOOTING, if
necessary.
7) Bring vehicle speed to 35 MPH. Depress speed control
RESUME/ACCEL switch. If vehicle resumes to previously set speed, go to
next step. If vehicle does not resume to previously set speed, repair
is not complete. Check for related TSBs and return to TROUBLE
SHOOTING, if necessary.
8) Hold down SET switch. Vehicle speed should decrease. If
vehicle speed decreases, go to next step. If vehicle speed did not
decrease, repair is not complete. Check for related TSBs and return to
TROUBLE SHOOTING, if necessary.
9) Ensure vehicle speed is more than 35 MPH and release SET
switch. If vehicle sets a new speed, go to next step. If vehicle did
not set a new speed, repair is not complete. Check for related TSBs
and return to TROUBLE SHOOTING, if necessary.
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.

away from mounting bracket to expose cable retaining clip. Remove
retaining clip. Remove servo.
Installation (All Models)
With throttle in full open position, align hole in speed
control cable sleeve with hole in servo pin. Install retaining clip.
To complete installation, reverse removal procedure. Tighten mounting
bolts/nuts to 75 INCH lbs. (8.5 N.m).
