Information:
The main display module is unable to identify system errors in simple open switch circuits or close switch circuits. No information (CID FMI) is available to assist the operator with troubleshooting.During normal operation, the possible fault conditions for the low coolant level switch are listed below.
The alert indicator ALWAYS FLASHES for the coolant level switch. In order to troubleshoot the "Always FLASHING" condition, see Alert Indicator Lamp Always FLASHING.
The alert indicator NEVER FLASHES for the coolant level switch. For the "NEVER FLASHES" procedure, see Alert Indicator Lamp NEVER FLASHES.Note: The indicator shows the open condition or the ground condition of the switch inputs. When the low coolant level switch is open, the alert indicator for the low coolant level switch FLASHES. When the input for the low coolant level is grounded, the alert indicator for the low coolant level switch is OFF. Therefore, in order to check a circuit, while the service person is watching for the correct result on the alert indicator, the service person is required to open switch number 6 (pin 32) and ground switch number 6 (pin 32).Alert Indicator Lamp Always FLASHING
This procedure is for the coolant level switch with a continuously flashing alert indicator.The "ALWAYS FLASHING" condition is probably caused by an undesired open circuit or a faulty main display module (unlikely condition).
Locate Switch 6 that always flashes the low coolant level indicator.
Turn the "ECS" switch to the OFF/RESET position.
Locate the switch that corresponds to the coolant level alarm that always flashes. If necessary, use the Electrical System Schematic to assist in locating the switch.
Check for loose terminal connections or corroded terminal connections to the switch.
Clean corroded terminals and tighten loose connections.
Check The Harness.
Disconnect the signal wire from the switch.
Connect a jumper wire from the signal wire to the ground wire. If a ground wire is not near, connect the signal wire to the battery ground.
Turn the ECS to the COOLDOWN/STOP position.Expected Result: The indicator lamp should stop flashing.Results:
No - The engine harness is open or the main display module has a problem. Proceed to 3.
Yes - The circuit is operating correctly. The switch has a problem. Check the switch or replace the switch.
Check The Harness.
Turn the ECS to the OFF/RESET position.
On the Electrical System Schematic, trace the signal wire from the switch (pin 32) to the Main Display Module.
Determine the connector contact number for the signal at the Main Display Module.
Disconnect the engine harness from the Main Display Module.
At the engine harness connector for the Main Display Module, measure the resistance that is between the signal contact and contact 2 (ground).Note: The jumper wire from 2 is still connected.Expected Result: The resistance should be less than 5.0 ohms.Results:
No - The resistance is greater than 5.0 ohms. The engine harness has a problem. Repair the engine harness or replace the engine harness.
Yes - The resistance is less than 5.0 ohms. The harness resistance is correct. The Main Display Module has a problem. Replace the Main Display Module. For more information on the subject,
