INTRODUCTION
 Before troubleshooting, verify customer complaints.
 If a vehicle malfunction is difficult to reproduce, harnesses, harness connectors or terminals may be mal-
functioning. Hold and shake these parts to make sure they are securely connected.
 When using a circuit tester to measure voltage or re sistance of each circuit, be careful not to damage or
deform connector terminals.

REMOVAL AND INSTALLATION
TransmitterINFOID:0000000001327599
REMOVAL
1. Deflate tire. Unscrew transmitter retaining nut and allow transmitter to fall into tire.
2. Gently bounce tire so that transmitter falls to bottom of tire. Place on tire changing machine and break both tire beads
ensuring that the transmitter rema ins at the bottom of the tire.
3. Turn tire so that valve hole is at bottom and bounce so that transmitter is near valve hole. Carefully lift tire onto turntable and
position valve hole (and transmitter) 270 degree from mounting/
dismounting head.
4. Lubricate tire well and remove first side of the tire. Reach inside the tire and remove the transmitter.
INSTALLATION
1. Put first side of tire onto rim.
2. Mount transmitter on rim and tighten nut.

3. Place wheel on turntable of tire machine. Ensure that transmitteris 270 degree from mounting head when second side of tire is
fitted.
NOTE:
Do not touch transmitter at mounting head.
4. Lubricate tire well and fit second side of tire as normal. Ensure that tire does not rotate relative to rim.
5. Inflate tire and fit to appropriate wheel position.
