Diagnostic Test

CHECK FOR CHARGING SYSTEM DTCS
1. With the scan tool, read Powertrain Control Module (PCM) DTCs.
  Are any Charging System DTCs set?
  
  Yes
  - Repair Charging System DTCs. Refer to DTC INDEX .
  - Perform the ESL VERIFICATION TEST. Refer to ELECTRONIC STEERING LOCK (ESL) VERIFICATION TEST
  No
  - Go To 2
CHECK IF VEHICLE WAS JUMP STARTED WITH 24-VOLT SYSTEM
NOTE:
Some Recreational Vehicles (RVs), Buses, and Semi Tractors use 24V systems.
1. Check if the vehicle was jump started by a vehicle with a 24-volt charging system.
  Was the vehicle jump started by a vehicle with a 24-volt charging system?
  
  Yes
  - With the scan tool, erase Electronic Steering Lock (ESL) Module DTCs.
  - Perform the ESL VERIFICATION TEST. Refer to ELECTRONIC STEERING LOCK (ESL) VERIFICATION TEST
  No
  - Go To 3
CHECK INDICATED ESL MODULE BATTERY VOLTAGE
1. Start the Engine and raise the engine speed to 2, 000 RPM.
2. With the scan tool, monitor the ESL Module Battery Voltage for 60 seconds.
  Does the ESL Module Battery Voltage read greater than 16 volts at any time during the test?
  
  Yes
  - Go To 4
  No
  - Perform the TESTING FOR AN INTERMITTENT CONDITION procedure. Refer to TESTING FOR AN INTERMITTENT CONDITION .
CHECK ESL MODULE VOLTAGE TO BATTERY VOLTAGE
1. Start the Engine and raise the engine speed to 2, 000 RPM.
2. With the scan tool, read the ESL Module Battery Voltage.
3. Measure the voltage at the Battery.
4. Compare the readings.
  Does the measured voltage reading match the scan tool ESL Module Battery Voltage reading?
  
  Yes
  - Repair the Charging System for an over charging condition in accordance with the Service Information.
  - Perform the ESL VERIFICATION TEST. Refer to ELECTRONIC STEERING LOCK (ESL) VERIFICATION TEST
  No
  - Go To 5
CHECK RELATED HARNESS CONNECTIONS
1. Disconnect all Electronic Steering Lock (ESL) Module harness connectors.
2. Disconnect all related in-line harness connections (if equipped).
3. Disconnect the related component harness connectors.
4. Inspect harness connectors, component connectors, and all male and female terminals for the following conditions:
  - Proper connector installation.
  - Damaged connector locks.
  - Corrosion.
  - Other signs of water intrusion.
  - Weather seal damage (if equipped).
  - Bent terminals.
  - Overheating due to a poor connection (terminal may be discolored due to excessive current draw).
  - Terminals that have been pushed back into the connector cavity.
  - Perform a terminal drag test on each connector terminal to verify proper terminal tension.
  Repair any conditions that are found.
5. Reconnect all ESL Module harness connectors. Be certain that all harness connectors are fully seated and the connector locks are fully engaged.
6. Reconnect all in-line harness connectors (if equipped). Be certain that all connectors are fully seated and the connector locks are fully engaged.
7. Reconnect all related component harness connectors. Be certain that all connectors are fully seated and the connector locks are fully engaged.
8. With the scan tool, erase DTCs.
9. Using the recorded Environmental Data, along with the When Monitored and Set Conditions above, operate the vehicle in the conditions that set the DTC.
10. With the scan tool, read ESL Module DTCs.
  Did the DTC return?
  
  Yes
  - Replace the Electronic Steering Lock (ESL) Module in accordance with the Service Information.
  - Perform the ESL VERIFICATION TEST. Refer to ELECTRONIC STEERING LOCK (ESL) VERIFICATION TEST
  No
  - Perform the ESL VERIFICATION TEST. Refer to ELECTRONIC STEERING LOCK (ESL) VERIFICATION TEST
  - Test complete.
