Important Safety Information

Work safely. Most accidents that involve product operation, maintenance, and repair are caused by failure to observe basic safety rules or precautions. An accident can often be avoided by recognizing potentially hazardous situations before an accident occurs.

A person must be alert to potential hazards. This person must also have the necessary training, skills, and tools in order to perform these functions properly.

Safety precautions and warnings are provided in this instruction and on the product. If these hazard warnings are not heeded, bodily injury or death could occur to you or to other persons. Caterpillar cannot anticipate every possible circumstance of a potential hazard.

Therefore, the warnings in this publication and the warnings that are on the product are not all inclusive. Avoid using a tool, a procedure, a work method, or operating technique that is not recommended by Caterpillar. If used, ensure the safety of the operating personnel and others.

Ensure that the product will not be damaged or the product will be made unsafe by the operation, lubrication, maintenance, or the repair procedures.

Illustration 7	g03480018
Above window location

Find a location for installing the PL421 module. Refer to Illustration 6 or Illustration 7 for possible locations.

Connect power, ground, and if available, J1939 datalink in service connector.

Note: Trucks without J1939 report location only, while trucks with J1939 report hours, location, and diagnostics.

GPS antenna installation

Cut matching pieces of Industrial Strength Velcro, approximately the same size of the GPS antenna. Locate the reinforcement rib closest to the right side of the cab. The GPS antenna will be mounted on the flat portion of the plastic surface, centered on the rib. To remove body oils from handling, wipe down the back of the GPS antenna and the plastic dash area with an alcohol wipe.

Allow the areas to air dry. Remove the tape from the Velcro and apply the self sticking adhesive backed Velcro to the dash and the back of the GPS antenna. Press the matching pieces of Velcro together to secure the antenna to the dash and rout the antenna wire as shown.

Location for Mounting the Antenna

Note: The antenna is preassembled with lock washer, nut, 0.5 mm (0.02 inch) coaxial cable and radio connectors. Brackets that are specific for the truck may be available for the application.

Check the list of parts for the truck.

To comply with regulations of FCC for RF human body safety, ensure that antenna is mounted more than 500 mm (19.7 inch) from truck operator.
Orient the antenna so that the top of the antenna is in a horizontal position with a clear 360 degree view of the sky. In-dash installation is acceptable/recommended depending on placement.
Mount the antenna more than 500 mm (19.7 inch) from the PL421 in order to minimize interference between the radio and the antenna.
Keep a distance between the PL421 antenna and other antennas that transmit a radio signal. Caterpillar recommends a distance of 1 m (3.3 ft). Keep no less than 500 mm (19.7 inch) between the PL421 antenna and other antennas that transmit a radio signal. The list of radio antennas to maintain a distance from include the citizen band radio, data radio and commercial communication radios.
Keep in mind the routing of the antenna cable. Do not route the antenna cable near any source of extreme heat (exhaust). Do not mount the antenna or the antenna cable so that the limitations of temperature −40° C (−40.0° F) and 85° C (185.0° F) are exceeded.
Route the antenna cable so the cable would not be subject to abrasion or pinching.
Route the antenna cable with a minimum bend radius of 49.5 mm (1.94 inch). Bend radius depends on the type of cable used. Do not bend the radius any less than ten times the diameter of the cable. The cable used is LMR 200UF .

The mounting hole diameter considered is 19 mm (0.75 inch).

Illustration 10	g02725227

Insert the provided pigtail cable into the PL421. Plug the pigtail cable into the dash harness.

Install the PL421 unit with bracket. Do not stretch the wires as stretching will cause intermittent operation of the PL421.

Install Blast Warning Label on visor.

Connecting to the CAN Data Link

The SAE J1939 data link is used to communicate information. The key components to note are as follows,

The total length of the data link between terminal resistors must not exceed 40 m (131.2 ft)
Length of each branch, or stub length, must not exceed 1 m (3.3 ft). Reference 165-0200 Cable As that is 0.15 m (0.492 ft)with deutsch connector DT 3 pin plug on one end and J1939 signal and shield wires with appropriate crimped socket on the other end for insertion into J1939 module connector
All splices and end nodes can be implemented using a connector tee. (Reference deutsch connector DT receptacle assembly 133-0970 Connector Receptacle As )
A terminal resistor is required at each end of the data link in order to ensure proper operation. (Reference deutsch connector DT plug with integrated termination resistor 174-3016 Connector Plug As ). One side is already terminated within PL421 module, so only one required.

Connect key switch into ignition circuitry.
Note: Various spade connectors for the ignition wire connections are used.

Terminate unused wires.

Record Status

If there is an issue with the installation or a question regarding the status at the time of installation, creating screenshots will aid in the investigation. Create screenshots before disconnecting Cat ET and leaving the truck.

Connect Communication Adapter and PC with Cat ET. With Key Switch ON, select the PL421 ECM. Allow the PL421 to access satellites and cell phone towers. Accessing the satellites and cell phone towers make take a few seconds.

Record screen shots of the ECM summary and all three Status Screens. Paste screen shots into Word file. Record VIN # in the same Word file.

Symptom Procedures

Electronic Service Tool Does Not Communicate with ECM

System Operation Description

During the installation of a PL421 system, the wiring harness is connected to the existing Data Link wiring on the truck. If the installation is not done properly, the continuity of the wiring may be open intermittently. This condition may not be apparent immediately. Improper installation will cause a problem when you are trying to connect the Caterpillar Electronic Technician (Cat ET) service tool to the truck.

Cat ET may report that no ECM has been found.
Cat ET may not report every ECM that is on the truck.
Cat ET may report an ECM but the ECM will not have any data.

If the Data Link wires for the PL421 are reversed, the ECM will not appear after connecting Cat ET.

Test Step 1. VERIFY THAT THE DATA LINK WIRES ARE NOT REVERSED.

Check that the positive Data Link wire (893-GN) in the wiring harness for the PL421 is connected to the positive Data Link wire of the wire harness for the truck.

Check that the negative Data Link wire (892-BR) in the wiring harness for the PL421 is connected to the negative Data Link wire of the wire harness for the truck.

Repair

Reinstall the Data Link wires correctly and check the operation of the PL421 module by using Cat ET.

STOP.

Test Step 2. CHECK THE WIRING WITH A MULTIMETER.

Turn off the truck and turn the disconnect switch to the OPEN position.

Measure the resistance of the negative Data Link wire from the service connector to the location for the spliced Data Link wire. Note the resistance.

Measure the resistance of the positive Data Link wire from the service connector (contact "D") to the location for the spliced Data Link wire. Note the resistance.

Expected Result

The resistance in both wires is less than 5 ohms.

Results

OK - The resistance is less than 5 ohms. Proceed to ""Test Step 3" ".
NOT OK - The resistance is greater than 5 ohms.

Repair

Repair the wiring harness. After repairing, resume the PL421 installation setup procedures.
