Section 23.2 Troubleshooting Flash Code 13, PID 111/FMI 4

Section 23.2
Troubleshooting Flash Code 13, PID 111/FMI 4

This diagnostic condition is typically:‪

  • Sensor signal is shorted to the sensor return circuit or to ground
  • Deteriorated coolant

Section 23.2.1
Check Sensor and Sensor Connector

Perform the following steps to check the sensor.‪

  1. Turn vehicle ignition OFF.
  2. Disconnect ECL Sensor.
  3. Turn ignition ON. Start engine and read logged codes.
  4. Stop engine.
    1. If code p 111/3 is logged, go to step 5 .
    2. If code p 111/4 is logged, refer to "23.2.2 Check for Short" .
  5. Inspect terminals at the CLS/ECL Sensor connector for bent, corroded and unseated pins or sockets. Ensure wires are not reversed at the CLS/ECL Sensor. See Figure "Engine Coolant Level Sensor" .
    1. If terminals and connectors are damaged, repair both. Refer to "23.2.2.1 Verify Repairs" .
    2. If terminals and connectors are not damaged, replace the ECL Sensor. Refer to "23.2.2.1 Verify Repairs" .

Section 23.2.2
Check for Short

Perform the following steps to check for a short.‪

  1. Turn ignition OFF.
  2. Disconnect the vehicle harness connector at the ECM/ECU.
  3. Measure resistance between sockets A and B on the CLS/ECL Sensor harness connector. Also measure resistance between socket A and battery ground; and socket A and chassis ground. See Figure "Engine Coolant Level Sensor" .

    1. If the resistance is greater than 10,000 Ω or open, go to step 4 .
    2. If the resistance is less than or equal to 10,000 Ω, the signal wire V-38 is shorted to the ground V-60, or to chassis ground. Repair short; refer to "23.2.2.1 Verify Repairs" .
  4. Inspect terminals at the CLS/ECL Sensor connector for bent, corroded and unseated pins or sockets. Ensure wires are not reversed at the CLS/ECL Sensor. See Figure "Engine Coolant Level Sensor" .
    1. If terminals and connectors are damaged, repair both. Refer to "23.2.2.1 Verify Repairs" .
    2. If terminals and connectors are not damaged, replace the ECL Sensor. Refer to "23.2.2.1 Verify Repairs" .
Section 23.2.2.1
Verify Repairs

Perform the following steps to verify repairs.‪

  1. Turn ignition OFF.
  2. Reconnect all connectors. Turn ignition ON.
  3. Clear diagnostic tool codes.
  4. Start and run the engine for one minute. Stop the engine.
  5. Check diagnostic tool for codes.
    1. If no codes are displayed, troubleshooting is complete.
    2. If code 111/4 is not logged, and other codes are logged, refer to "18.3 First Step for Diagnosing a Fault Within the DDEC System" .
    3. If code 111/4 is logged, refer to "23.2.3 Code 111/4 Logged" .

Section 23.2.3
Code 111/4 Logged

Perform the following steps to troubleshoot Code 111/4.‪

  1. Remove CLS/ECL Sensor.
  2. Plug opening.
  3. Place the sensor probe in clean water.
  4. Start and run the engine for one minute.
  5. Check diagnostic tool for codes.
    1. If code 111/4 is logged, review this section to find the error. Refer to "23.2.1 Check Sensor and Sensor Connector" .
    2. If code 111/4 is not logged, reprogram the ECM/ECU and replace the coolant with new. Repeat the test. Refer to "23.2.2.1 Verify Repairs" .
