Low Batt Caddy

This bulletin applies to 2012 Cadillac SRX models. DTC P062F may be set in the ECM, active or in history. This code can falsely set during a low battery condition. This can also trigger certain HO2S heater sensor codes (P0030, P0036, P0050, P0053, P0054, P0059, P0060, P0135, P0141, P0155 and/or P0161).

Important: Do not diagnose the HO2S heater sensor codes until the P062F has been corrected.

If only these codes are set and the vehicle is not exhibiting low battery symptoms, clear the DTCs and perform a couple of engine starts allowing the engine to run for a minute, then shut down and allow the ECM to power down for about one minute.

Re-start the engine. If no DTCs reset, no further action is required. If the DTCs do reset, check the ECM power and ground circuits, as low voltage to the ECM can cause these DTCs to set.
