RKE Fob Battery Low
RKE FOB BATTERY LOWWHEN MONITORED
Upon activation of any button on the Remote Keyless Entry transmitter (fob).
SET CONDITION
The RKE module monitors the input from the fobs and determines if the voltage is within tolerance. If the battery voltage of the RKE fob falls between 2.0 and 3.5 volts the RKE module will communicates this to the Instrument Cluster which in turn will set this code.
POSSIBLE CAUSES
- Batteries low RKE
- Transmitter - low voltage output
Diagnostic Test
1. CHECK TROUBLE CODE
Turn the ignition on.
Using the RKE transmitter, press the UNLOCK button six times or more.
With the DRBIII(R), read DTCs.
Q: Does the DRBIII(R) display RKE KEY FOB BATTERY LOW?
YES: Go To 2
NO: Problem is intermittent and not present at this time. Check the other transmitters used with this vehicle to determine which one set the code. Check the voltage of each battery in FOB and ensure they above 2.9 volts each. Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
2. BATTERIES LOW
Test the voltage of each battery in the RKE transmitter.
Q: Is the voltage at or above 2.9 in each battery?
YES: Replace the RKE Transmitter. Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
NO: Replace the batteries and press the unlock button on the transmitter six times to clear the DTC. Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
