PINPOINT TEST H: THE REMOTE KEYLESS ENTRY (RKE) MODULE DOES NOT RESPOND TO THE DIAGNOSTIC TOOL

Test H1-H3:

Test H4-H5:

Normal Operation
Power is supplied to the remote keyless entry (RKE) module through circuit 29-AA17 (OG/WH). Circuit 31-AA17 (BK/WH) provides the module ground. The RKE module communicates with the diagnostic tool through the standard corporate protocol (SCP) communications network. Circuits 4-EG13 (GY/OG) and 5-EG13 (BU/BK) receive and transmit data from the RKE module to the data link connector (DLC) through the interior auxiliary junction box (AJB). Degraded SCP performance occurs if one bus line is open, shorted to ground or voltage or if one but not all termination resistors are lost.

Possible Causes
- circuit 29-AA17 (OG/WH) open or short to ground
- circuit 31-AA17 (BK/WH) open
- circuit 4-EG13 (GY/OG) open
- circuit 5-EG13 (BU/BK) open
- RKE module C4071
- RKE module
