WARNING
UNDER NO CIRCUMSTANCE SHOULD INSTALLATION OF THIS KIT BE PERFORMED USING ELECTRICALLY POWERED
EQUIPMENT. DOING SO CAN RESULT IN PERSONAL INJURY. MAKE SURE THAT THE IGNITION SWITCH IS IN THE OFF
POSITION WITH THE KEY REMOVED FROM IGNITION AND THE BATTERY TERMINALS (POSITIVE AND NEGATIVE)
REMOVED BEFORE YOU START THE INSTALLATION OF THIS KIT TO AVOID PERSONAL INJURY, ELECTRICAL SHOCK
AND/OR DAMAGE TO THE VEHICLE’S ELECTRICAL SYSTEM. REMOVING THE AIR BAG FROM THE STEERING WHEEL
COULD CAUSE INJURY AND/OR DEATH TO YOU OR ANY PERSON WORKING WITH YOU. REFER TO MANUFACTURER AIR
BAG SERVICE MANUAL. DO NOT DISCONNECT THE AIR BAG WIRING HARNESS FOR ANY REASON, WHICH MAY CAUSE
DAMAGE TO YOU AND/OR THE VEHICLE’SAIR BAG SYSTEM.
CAUTION

TROUBLESHOOTING
VERIFY VOLTAGES AT REAR OF THE RECEIVER MODULE CONNECTOR (FIGURE 14) USING A VOLT-OHM METER. ENSURE THE
PROBE TIPS ARE CONTACTING THE METAL TERMINALS.
1. CHECK VOLTAGE BETWEEN THE BLUE WIRE (POWER, PIN 1) AND THE BLACK WIRE (GROUND, PIN 10) WITH KEY ON
AND OFF. VOLTAGES SHOULD BE:
KEY ON 12-14 VOLTS (BATTERY VOLTAGE)
KEY OFF BELOW 1 VOLT
IFVOLTAGE ISN’T PRESENT, OR IS PRESENT REGARDLESS OF KEY POSITION, VERIFY THAT THE BLUE POWER WIRE IS
CONNECTED AS STATED IN STEP 4 OF THE INSTRUCTIONS. THE POWER WIRE SHOULD HAVE VOLTAGE ONLY WHEN THE
KEY IS IN THE ON OR ACC POSITION. IF NO VOLTAGE IS PRESENT, ALSO VERIFY THE GROUND CONNECTION ACCORDING
TO STEP 8 AND THE VEHICLE FUSE FOR THE CIRCUIT.
2. CHECK VOLTAGE BETWEEN THE RED WIRE (CRUISE ON, PIN 7) AND THE BLACK WIRE (GROUND, PIN 10) WITH KEY ON
AND OFF. VOLTAGES SHOULD BE:
KEY ON 12-14 VOLTS (BATTERY VOLTAGE)
KEY OFF BELOW 1 VOLT
IFVOLTAGE ISN’T PRESENT, OR IS PRESENT REGARDLESS OF KEY POSITION, VERIFY THAT THE GRAY WIRE IS CONNECT-
ED AS STATED IN STEP 5 OF THE INSTRUCTIONS.
3. WITH KEY IN THE ON POSITION, PRESS SET ON THE TRANSMIT MODULE TO TURN THE SYSTEM ON. VERIFY THE
INSTRUMENT PANEL “CRUISE” LIGHT ILLUMINATES. (NOTE: BASE LEVEL V6 TUNDRA HAS NO DASH LIGHT.) NEXT VER-
IFY THE FOLLOWING VOLTAGES ON THE RED WIRE OF THE RF HARNESS CONNECTOR ARE WITHIN A VOLT OF THE FOLLOW-
ING AS BUTTONS ARE PRESSED AND HELD:
SET 6 VOLTS
RESUME 3 VOLTS
NOPRESS 12-14 VOLTS (BATTERY VOLTAGE)
IF VOLTAGES ARE DIFFERENT THAN ABOVE, VERIFY THE CONNECTION AT THE GRAY WIRE IS AS DESCRIBED IN STEP 5 OF
THE INSTRUCTIONS.
IF THE ABOVE STEPS 1 AND 2 SHOW NORMAL VOLTAGES, BUT INSTRUMENT PANEL “CRUISE” LIGHT DOES NOT ILLUMI-
NATE AND VOLTAGES DO NOT CHANGE WITH BUTTON PRESS AS DESCRIBED IN STEP 3, REPLACE BOTH THE TRANSMITTER
AND RECEIVER.

SPEED CONTROL OPERATING
INSTRUCTIONS
ON- THE CRUISE CONTROL IS AUTOMATICALLY TURNED ON
WITH IGNITION POWER. HOWEVER, ONCE THE CRUISE
CONTROL HAS BEEN MANUALLY TURNED OFF BY PRESSING
BOTH BUTTONS AS DESCRIBED BELOW, IT CAN BE
MANUALLY TURNED BACK ON BY MOMENTARILY PRESSING
THE “SET/DECEL” BUTTON ALSO LABELED “ON”.
SET SPEED- TO ENGAGE SYSTEM, DRIVE AT ANY SPEED
ABOVE 33 MPH (50 KPH), PRESS “SET/DECEL” AND
RELEASE, THEN REMOVE YOUR FOOT FROM THE
ACCELERATOR PEDAL. THE CRUISE CONTROL WILL SET AT
THE SPEED OF THE VEHICLE WHEN BUTTON IS RELEASED
PLUS OR MINUS 1- 1/2 MPH (3 KPH).
COAST- PRESS AND HOLD THE “SET/DECEL” BUTTON
AND YOUR SPEED WILL DECREASE. RELEASE BUTTON AND
SPEED OF VEHICLE AT TIME BUTTON IS RELEASED WILL BE
NEW SET SPEED IF ABOVE 33 MPH (50KPH).
ACCEL- PRESS AND HOLD THE “RESUME/ACCEL”
BUTTON AND YOUR SPEED WILL INCREASE. RELEASE
BUTTON AND YOU WILL HAVE A NEW HIGHER SET SPEED.
TAP-UP- YOU CAN GRADUALLY INCREASE YOUR SPEED BY
QUICKLY PRESSING AND RELEASING THE “RESUME/
ACCEL” BUTTON. EACH TIME YOU PRESS AND RELEASE
THE BUTTON YOUR SPEED WILL INCREASE BY ONE TO TWO
MPH (ONE AND A HALF TO THREE KPH).
TAP-DOWN- YOU CAN GRADUALLY DECREASE YOUR
SPEED (ON SELECTED CRUISE CONTROL MODULES ONLY)
BY QUICKLY PRESSING AND RELEASING THE
”SET/DECEL” BUTTON. EACH TIME YOU PRESS AND
RELEASE THE BUTTON YOUR SPEED WILL DECREASE BY
ONE OR TWO MPH (ONE AND A HALF TO FIVE KPH).
DISENGAGE- DEPRESS BRAKE PEDAL SLIGHTLY -
AUTOMATIC SPEED CONTROL WILL CEASE BUT SET SPEED
WILL STAY IN SYSTEM’S MEMORY. ALSO, YOU CAN DISEN-
GAGE BY PRESSING BUTTON TO OFF POSITION, BUT THIS
ERASES THE MEMORY. TO GET THE RESUME FEATURE
TO WORK AGAIN, YOU MUST FIRST SET A SPEED. TURNING
OFF THE IGNITION ALSO CLEARS THE SYSTEM’S MEMORY.
RESUME- AFTER DISENGAGING SYSTEM WITH BRAKE OR
CLUTCH, RETURN TO SET SPEED BY DRIVING ABOVE 33
MPH (50 KPH). THEN PRESS “RESUME/ACCEL”
BUTTON AND RELEASE IT. IF ACCELERATION RATE IS
FASTER OR SLOWER THAN YOU LIKE, DRIVE TO WITHIN A
FEW MPH OF YOUR SET SPEED, THEN PRESS AND RELEASE
THE RESUME/ACCEL BUTTON.
OFF- PRESS AND HOLD BOTH BUTTONS SIMULTANEOUSLY
TO DISENGAGE AND TURN OFF THE CRUISE CONTROL. THE
CRUISE CONTROL WILL NO LONGER ACCEPT ANY CONTROL
SIGNALS UNTIL A NEW SET SPEED IS ESTABLISHED.
THINGS YOU SHOULD KNOW ABOUT
YOUR CRUISE CONTROL SWITCH
THE CRUISE CONTROL SWITCH IS POWERED BY A 3V LITHI-
UM BATTERY, AND EVENTUALLY IT WILL NEED TO BE
REPLACED. THE CRUISE CONTROL SWITCH HAS A DIAGNOS-
TIC FEATURE WHICH ALERTS THE DRIVER IF THE BATTERY
NEEDS TO BE REPLACED. WHEN THE SWITCH BATTERY IS
LOW, THE CRUISE CONTROL IS INOPERATIVE.
TO REPLACE A LOW BATTERY IN THE SWITCH:
1. REMOVE THE SWITCH FROM THE STEERING WHEEL BY
FIRMLY GRASPING ON THE SIDES AND PULLING STRAIGHT
UPWARD AWAY FROM THE STEERING WHEEL.
2. REMOVE THE BATTERY LOCATED ON THE BACK OF THE
SWITCH BY GENTLY PRYING ONE SIDE OF THE BATTERY UP
WITH A JEWELER’S SCREWDRIVER OR SIMILAR INSTRUMENT.
NOTE THE POSITION OF THE BATTERY TO AID IN PROPER
REPLACEMENT.
3. REPLACE THE BATTERY WITH A 3V LITHIUM MODEL
CR2032 OR EQUIVALENT BY FIRST INSERTING AT AN
ANGLE, THEN GENTLY PRESSING UNTIL BATTERY IS SEATED
FLAT WITH THE SIDE OF THE BATTERY MARKED “+” IN
VIEW.
4. REPLACE THE SWITCH ON THE STEERING WHEEL BY
REVERSING THE PROCEDURE BY WHICH IT WAS REMOVED.
