DTC P26C3

DTC P26C3: Internal Control Module Transmission Range Sensor Performance

General Description

Courtesy of HONDA, U.S.A., INC.

If input information from the input circuit is abnormal during shifting the R, N, or D switch, the powertrain control module (PCM) receives malfunction from the SBW shifter control module, and stores a DTC.

Monitor Execution, Sequence, Duration, DTC Type

Execution	Continuous
Sequence	None
Duration	Depending on the driving conditions
DTC Type	One drive cycle, MIL off, Shift position indicator blinks

Enable Conditions

Condition
Vehicle	ON mode

Malfunction Threshold

Either one of the condition is met:

RSW1 or RSW3 is ON for at least 200 milliseconds when shifting the transmission to other than R position/mode.
RSW2 is ON for at least 1 minute when shifting the transmission to other than R position/mode.
Either RSW1, RSW2, or RSW3 is OFF for at least 10 times when shifting the transmission to R position/mode.
NSW1 or NSW3 is ON for at least 200 milliseconds when shifting the transmission to other than N position/mode.
NSW2 is ON for at least 1 minute when shifting the transmission to other than N position/mode.
Either NSW1, NSW2, or NSW3 is OFF for at least 10 times when shifting the transmission to N position/mode.
DSW1 or DSW3 is ON for at least 200 milliseconds when shifting the transmission to other than D position/mode.
DSW2 is ON for at least 1 minute when shifting the transmission to other than D position/mode.
Either DSW1, DSW2, or DSW3 is OFF for at least 10 times when shifting the transmission to D position/mode.

Possible Cause

NOTE: The causes shown may not be a complete list of all potential problems, and it is possible that there may be other causes.

SBW shifter assembly internal failure

Confirmation Procedure

Operating Condition

Shift the transmission to other than R position/mode for at least 1 minute.
Shift the transmission to R position/mode for at least 10 times.
Shift the transmission to other than N position/mode for at least 1 minute.
Shift the transmission to N position/mode for at least 10 times.
Shift the transmission to other than D position/mode for at least 1 minute.
Shift the transmission to D position/mode for at least 10 times.

With the HDS

None.

Diagnosis Details

Conditions for setting the DTC

When a malfunction is detected, the shift position indicator blinks and a Pending DTC, a Confirmed DTC, and the freeze data are stored in the PCM memory. The MIL does not come on.

Conditions for clearing the DTC

The shift position indicator comes off by turning the vehicle to the OFF (LOCK) mode. The Pending DTC, the Confirmed DTC, and the freeze data can be cleared with the scan tool Clear command or by disconnecting the 12 volt battery.
