1999 DODGE RAM engine

Ram Pickup
1) Raise and support vehicle. Inspect shift linkage for worn
components. Replace any damaged or worn grommets or shift linkage
components before adjusting.
2) Ensure shift lever is in Park. Loosen lock bolt on
adjusting swivel. See Fig. 7. Ensure shift rod slides freely in
adjusting swivel. If shift rod fails to slide freely in adjusting
swivel, lubricate shift rod as necessary.
3) Rotate transmission shift lever fully toward rear of
vehicle to the Park detent position. Position adjusting swivel so it
is centered in grommet on torque shaft arm. See Fig. 7. Tighten lock
bolt on adjusting swivel. Check that engine only starts with shift
lever in Park and Neutral. If engine starts in any other gears except
Park and Neutral, shift linkage adjustment is incorrect or
park/neutral position switch is defective.

THROTTLE VALVE CABLE
1) Ensure shift lever is in Park and ignition is off. Remove
air cleaner. Disconnect throttle valve cable from stud on throttle
lever at throttle body.
2) Ensure throttle lever on throttle body is in idle position
and throttle valve lever on transmission is in idle (fully forward)
position.
3) Using small screwdriver, remove retaining clip from
throttle valve cable. Center end of throttle valve cable with stud on
throttle lever at throttle body within .039" (1.00 mm), and install
retaining clip. Install throttle valve cable on throttle lever.
4) To verify proper adjustment, ensure throttle valve lever
on throttle body and throttle lever on transmission move

simultaneously when throttle is depressed. If both levers to do not
move simultaneously, readjust throttle valve cable.
TRANSFER CASE SHIFT LINKAGE
Dakota
1) Place transfer case shift lever in 4L position. Use wire
or bungie cord to secure transfer case shift lever in 4L position.
Raise and support vehicle. Loosen lock bolt at adjusting swivel on
shift rod. See Fig. 8. Ensure shift rod slides freely in adjusting
swivel. If shift rod fails to slide freely in adjusting swivel,
lubricate shift rod as necessary.
2) Ensure shift lever on transfer case is still in 4L
position. Ensure pin on end of adjusting swivel is centered in hole on
shift arm. Tighten lock bolt. With all wheels off floor, start engine
and shift transfer case through all ranges to ensure proper operation.
3) Ensure pin on end of adjusting swivel is centered in hole
on shift arm. Tighten lock bolt. With all wheels off floor, start
engine and shift transfer case through all ranges to ensure proper
operation.

1) Place transfer case shift lever in 2H position. Use wire

or bungie cord to secure transfer case shift lever in 2H position.
2) Raise and support vehicle. Loosen lock bolt at adjusting
swivel on shift rod. See Fig. 8. Ensure shift rod slides freely in
adjusting swivel. If shift rod fails to slide freely in adjusting
swivel, lubricate shift rod as necessary.

INTRODUCTION
This article contains underhood views or schematics of vacuum
hose routing. Use these vacuum diagrams during the visual inspection
in appropriate BASIC DIAGNOSTIC PROCEDURES article. This will assist
in identifying improperly routed vacuum hoses, which may cause
driveability and/or computer-indicated malfunctions.
VACUUM DIAGRAMS
NOTE: References to California models apply to California emission
vehicles, which may be verified by underhood Emission Control
label. California emissions may be available in other
states.
NOTE: Vacuum diagrams for applications not shown were not available
at time of publication. See underhood Emission Control
label.

4) Move jumper to instrument cluster connector C1 terminal
No. 9 (White/Black wire). Monitor CCD BUS VOLTAGE. If scan tool
voltage did not drop to about zero volts, repair open White/Black
wire. If scan tool voltage did not drop to about zero volts, replace
instrument cluster.
NO RESPONSE POWERTRAIN CONTROL MODULE
NOTE: For connector terminal identification and wiring diagrams,
see BODY CONTROL COMPUTER - INTRODUCTION article. Perform
VERIFICATION TEST VER-1 after each repair.
CAUTION: Always turn ignition off prior to disconnecting any module
connector.
1) If engine does not run, see appropriate BASIC DIAGNOSTIC
PROCEDURES article in ENGINE PERFORMANCE section. If engine runs, go
to next step.
2) Turn ignition off. Disconnect Powertrain Control Module
(PCM). PCM is mounted in right side of firewall. Turn ignition on.
Connect jumper wire between ground and PCM connector C3 terminal. No.
30 (Violet/Brown wire). Using scan tool, perform CCD BUS test. If scan\
tool does not display SHORT TO GROUND, repair open Violet/Brown wire.
If scan tool displays SHORT TO GROUND, go to next step.
3) Move jumper wire to PCM connector C3 terminal No. 28
(White/Black wire). Perform CCD BUS test. If scan tool does not
display SHORT TO GROUND, repair open White/Black wire. If scan tool
displays SHORT TO GROUND, replace PCM.
NO RESPONSE COMPASS/MINI-TRIP SYSTEM
NOTE: For connector terminal identification and wiring diagrams,
see BODY CONTROL COMPUTER - INTRODUCTION article. Perform
VERIFICATION TEST VER-1 after each repair.
CAUTION: Always turn ignition off prior to disconnecting any module
connector.
1) Remove and inspect fuse No. 11 from junction block.
Junction block is on left side of instrument panel. If fuse is open,
go to next step. If fuse is okay, go to step 3).
2) Using external ohmmeter, measure resistance between ground
and fused ignition switch output run/start terminal (Dark Blue/White
wire) on fuse No. 11 socket. If resistance is less than 5 ohms, repair
Dark Blue/White wire for short to ground. Replace fuse No. 11. If
resistance is 5 ohms or more, replace fuse No. 11.
3) Reinstall fuse. Disconnect CMTC 12-pin connector. Turn
ignition on. Using external voltmeter, measure voltage between ground
and CMTC connector terminal No. 1 (Dark Blue/White wire). If voltage
is less than 9.5 volts, repair open Dark Blue/White wire. If voltage
is 9.5 volts or more, go to next step.
4) Using external voltmeter, measure voltage between ground
and CMTC connector terminal No. 5 (Pink wire). If voltage is less than\
9.5 volts, repair open Pink wire. If voltage is 9.5 volts or more, go
to next step.
5) Turn ignition off. Using external ohmmeter, measure
resistance between ground and CMTC connector terminal No. 7
(Black/Light Green wire). If resistance is 5 ohms or less, go to next
step. If resistance is more than 5 ohms, repair open Black/Light Green
wire.
6) Using scan tool, perform CCD bus test. Connect jumper wire
between ground and CMTC connector terminal No. 2 (Violet/Brown wire).
If scan tool displays BUS (+) SHORTED TO GROUND, go to next step. If

more, go to next step.
9) Measure resistance between ground and DLC connector
terminal No. 11 (White/Black wire). If resistance is less than 700
ohms, repair White/Dark Green wire for short to ground. If resistance
is 700 ohms or more, replace scan tool cable or scan tool as
necessary.
VERIFICATION TEST VER-1
1) Reconnect all previously disconnect connectors. Turn
ignition on, engine off. Using scan tool, erase all fault messages.
Turn ignition off. Wait 10 seconds. Turn ignition on, engine off.
Operate system that is malfunctioning. If system does not operate
properly, perform SYMPTOM IDENTIFICATION of BODY CONTROL COMPUTER
TESTS - RAM PICKUP article. If system operates properly, go to next
step.
2) Using scan tool, read fault messages. If fault messages
exist, perform SYMPTOM IDENTIFICATION of BODY CONTROL COMPUTER TESTS -
RAM PICKUP article. If fault messages do not exist, repair is
complete.
