Variations of DTC P0087 are stored in the PCM for the fuel rail pressure sensor. - [LTB01156NAS1](/bulletins/10138749.md), 2018-05-29, Service bulletin: ELECTRICAL SYSTEM; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE \(TCM/PCM/TECM\); ENGINE. The engine Malfunction Indicator Lamp \(MIL\) may be illuminated on the Instrument Cluster \(IC\) with Diagnostic Trouble Code \(DTC\) P132B\-77 stored in the Powertrain Control Module \(PCM\). - [SGI18\-05](/bulletins/10138657.md), 2018-05-29, Service bulletin: POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE \(TCM/PCM/TECM\); ELECTRICAL SYSTEM. An issue has been identified on certain vehicles within the listed Affected Vehicle Range where the 'Service Required' message will not appear on the Instrument Cluster \(IC\) if a vehicle has reached its service point and the engine is started normally by pressing the engine START/STOP button with the brake pedal pressed. Turning on the ignition only, by pressing the engine START/STOP button without the brake pedal pressed, will still allow the 'Service Required' warning message to be displayed. In addition, the latest Powertrain Control Module \(PCM\) software has introduced a concern relating to the ability to reset the service message indicator. The latest IC software will rectify these concerns. - [LTB\-00871\-NAS\-1](/bulletins/10133623.md), 2018-04-17, Service bulletin: POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE \(TCM/PCM/TECM\); EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL. Situation: After a Service Interval Reset, the Service Interval Indicator \(SII\) may appear on the Instrument Cluster \(IC\) for less than one second when no service is required. Cause: This may be caused by a discrepancy between the values in the Powertrain Control Module \(PCM\) and the IC for next service initialization. - [N118NAS1](/bulletins/10130729.md), 2018-04-02, Service bulletin: POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE \(TCM/PCM/TECM\).
