one or more of the following DTCs C0750, C0755, C0760, C0765

Condition/Concern
Some customers may comment that the remote keyless entry (RKE) transmitter range is very poor and they have to
be very close to the vehicle before the transmitter operates. They may also comment that the tire pressure monitor
(TPM) system indicates dashes for the rear tire pressure readings.
Recommendation/Instructions
Verify the remote keyless entry transmitter range by pacing off approximately 9 m (30 ft) diagonally on all four
corners of the vehicle. If the RKE range is good, follow the appropriate TPM Diagnostics using Global Service
Information (SI). If the RKE range is poor, or has a TPM DTC present, replace the remote control door lock receiver
(RCDLR) module.
