Diagnostic Test

WARNING: This page is about a different variant/trim than selected.

CHECK FOR AN ACTIVE DTC
WARNING:
On vehicles equipped with the high voltage system, you must thoroughly read and follow all High Voltage Safety procedures. In addition, before performing any diagnostic or service procedure near a high voltage component, you must carry out the High Voltage Power Down. Failure to follow these instructions may result in possible serious or fatal injury.

Read the HIGH-VOLTAGE SAFETY PROCEDURES. Refer to HIGH VOLTAGE SAFETY PROCEDURES

When the HIGH-VOLTAGE POWER-DOWN PROCEDURE is necessary. Refer to HIGH VOLTAGE POWER DOWN .

NOTE:
An external Radio-Frequency Identification (RFID) key (and/or pass/radio key), such as one used to gain access to a 24 hour gym, can cause this DTC to set and create a no start condition. Inspect the customer's key chain for any type of RFID key. If one is not found, ask the customer to check if a spare key chain has this RFID key on it or if it was removed from the original key chain before the vehicle was released for service. If a RFID key is present, remove the ignition key from the vehicle and remove the RFID key from the key chain.
1. With the scan tool, read Hybrid Control Processor (HCP) DTCs and record on the repair order.
2. Record the Freeze Frame Data (If available), Event Data (If available), and Environmental Data.
3. With the scan tool, erase DTCs.
4. Using the recorded data, along with the When Monitored and Set Conditions above, operate the vehicle in the conditions that set the DTC.
5. With the scan tool, read HCP DTCs.

  Is P2534 or P2535 DTCs active?
  
  Yes
  - Repair DTCs in accordance with the appropriate Diagnostic Information.
  - Perform the Hybrid Control Processor (HCP) VERIFICATION TEST. Refer to HYBRID CONTROL PROCESSOR (HCP) VERIFICATION TEST .
  No
  - Go To 4
CHECK THE FOBS
NOTE:
All FOB's that are used on this vehicle must be available to perform this test.
1. Use each FOB, one at a time, to attempt to start the vehicle with all others not in use at least 10 feet from the vehicle.
2. With the scan tool, check for any FOB related DTCs in the BCM, PCM, or RF Hub.
  Are there any related BCM, PCM, or RF Hub DTCs set?
  
  Yes
  - Repair the DTCs in accordance with the appropriate Diagnostic Information.
  - Perform the Hybrid Control Processor (HCP) VERIFICATION TEST. Refer to HYBRID CONTROL PROCESSOR (HCP) VERIFICATION TEST .
  No
  - Go To 5
CHECK PROGRAMMED VIN IN EACH MODULE
1. With the scan tool, check all of the modules for the correct VIN.
  Do all of the modules have the correct VIN programmed?
  
  Yes
  - Go To 6
  No
  - Program the modules with the correct VIN in accordance with the Service Information.
  - Perform the Hybrid Control Processor (HCP) VERIFICATION TEST. Refer to HYBRID CONTROL PROCESSOR (HCP) VERIFICATION TEST .
CHECK RELATED HARNESS CONNECTIONS
1. Disconnect all PIM 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 PIM 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 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 HCP DTCs.
  Did the DTC return?
  
  Yes
