Pin locations for the warning lamp circuitTest Step 1. Inspect Electrical Connectors and Wiring
Thoroughly inspect the J1/P1 ECM connector, the firewall bulkhead connector, and terminal 29. Refer to Illustration 2. Refer to Troubleshooting, "Electrical Connectors - Inspect" for details.
Perform a 45 N (10 lb) pull test on each of the wires in the ECM connector that is associated with the suspect terminal for the lamp.
Check the ECM connector (allen head screw) for the proper torque of 6.0 N m (55 lb in).
Check the harness and wiring for abrasion and pinch points from the battery to the ECM.Expected Result:All connectors, pins and sockets should be completely coupled and/or inserted and the harness and wiring should be free of corrosion, abrasion or pinch points.Results:
OK - Proceed to Test Step 2.
Not OK - Repair: Repair the connectors or wiring and/or replace the connectors or wiring. Ensure that all of the seals are properly in place and ensure that the connectors are completely coupled.STOPTest Step 2. Check for Normal Operation of the Warning Lamp (s)
Monitor the warning lamp. Turn the key switch to the ON position, while the engine is off. The lamp should turn on for five seconds. Then, the lamp should turn off.The lamp will continue flashing if there is an active diagnostic code. If there is an active diagnostic code, connect the Caterpillar Electronic Technician (Cat ET) in order to read the active diagnostic code. Troubleshoot the problem.Note: The warning lamp will not turn on until the engine is cranked.
The "Engine Monitoring Lamps" parameter must be programmed to "Option 1" in order for the following lamps to function.
J1/P1:29 Low Oil Pressure
J1/P1:30 Low Coolant Level Warning
J1/P1:31 High Coolant TemperatureThe lamp for the low coolant level also requires the "Coolant Level Sensor" parameter to be programmed to the "4-pin" option or the "2 wire Float Sensor" option.While the warning lamp is being observed, start the engine. The warning lamp should turn on for a minimum of two seconds after the engine starts. Then, the warning lamp should turn off. If the lamp remains on, immediately shut down the engine.
While the warning lamp is being observed, start the engine. The warning lamp should turn on for a minimum of two seconds after the engine starts. Then, the warning lamp should turn off. If the lamp remains off, immediately shut down the engine.Expected Result:The warning lamp turns on and the warning lamp turns off per the above description.Results:
OK - The lamp appears to operating correctly at this time.STOP
Not OK - The lamp does not turn on. Proceed to Test Step 3.
Not OK - The lamp stays on. Proceed to Test Step 3.Test Step 3. Test the Lamp Circuit

Vehicle harness connector P1
Disconnect the J1/P1 ECM connector.
Fabricate a jumper wire 100 mm (4 inch) long. Crimp a Deutsch pin to both ends of the wire.
Insert the jumper into the terminal of the suspect lamp of connector P1. The jumper can be inserted into the following terminals in order to test the appropriate lamp circuit:
P1:31 (High Coolant Temperature Lamp, Fast Idle Enable Lamp, or Wait To Start Lamp)
P1:29 (Warning Lamp or Low Oil Pressure Lamp)
P1:30 (PTO Switch On Lamp or Low Coolant Level Lamp)
Connect the other side of the jumper wire to P1:65 (-battery).
Turn the key switch to the ON position.
While the lamp is being monitored, insert the jumper wire and remove the jumper wire. Refer to Illustration 3.Expected Result:Result 1 The warning lamp turns on while the jumper is connected to both sockets. Also, the warning lamp turns off when the jumper is removed from one of the sockets.Result 2 The lamp does not turn on while the jumper is connected to both sockets.Result 3 The lamp will stay on while the ECM vehicle harness connector is disconnected.Results:
Result 1 - The warning lamp circuit is functioning properly. Proceed to Test Step 4.
Result 2 - The lamp did not turn on. The vehicle's lamp circuit is not functioning properly. The lamp is probably burned out or there is a problem in the wiring from the cab to either the ECM or the +battery connection. Repair the lamp circuit or send the vehicle to the OEM dealer for repairs.STOP
Result 3 - Repair: Perform the following diagnostic procedure:The circuit between the ECM and the lamp is shorted to chassis ground. Repair the circuit or send the vehicle to the OEM dealer for repairs.STOPTest Step 4. Check the Operation of the ECM Output for the Warning Lamp

ECM breakout T-connector
Disconnect the J1/P1 ECM connector.
Insert a 140-2266 Cable (Seventy-Pin Breakout) between the ECM connectors J1 and P1.
Connect a test light probe to terminal 63 (-battery) and connect the other probe to terminal 48 (unswitched +battery) of the breakout T.
The test lamp should turn on. If the test lamp does not turn on, either the test lamp is faulty or the wiring to the ECM is faulty. Continue with this step if the lamp turns on.
Leave the test light probe connected to one of the following terminals:
P1:48 unswitched +battery
P1:52 unswitched +battery
P1:53 unswitched +battery
P1:55 unswitched +battery
Connect the other test light probe to terminal 29 on the breakout T.Refer to Illustration 4.
Watch the voltage test lamp. Start the engine. The lamp should turn on for a minimum of two seconds after the engine starts. Then, the lamp should
