Transmission Control Switch Circuit
DESCRIPTION
After moving the shift lever to S, it is possible to switch the shift range between
"1" (S1 range) and "6" (S6 range) using the transmission control switch.
Moving the shift lever to "+" once raises the shift range by one, and moving
the shift lever to ...
Short in Side Squib RH Circuit (B1820/55-B1823/55)
DESCRIPTION
The side squib RH circuit consists of the airbag sensor assembly and the front
seat airbag assembly RH.
The circuit signals the SRS to deploy when airbag deployment conditions are met.
These DTCs are set when a malfunction is detected in the side squib RH circuit.
