DTC C2191/91 Vehicle Speed Signal Error
CIRCUIT DESCRIPTION
The tire pressure monitor ECU receives a speed signal from the combination meter. This DTC is stored upon
entering test mode but erased when a vehicle speed signal of 12 mph (20 km/h) is detected for 3 seconds
or more. The DTC is output only in test mode.
DTC No.DTC Detecting ConditionTrouble Area
C2191/91Speed sensor circuit malfunction.

Tire Pressure Warning Lamp Circuit
CIRCUIT DESCRIPTION
If the ECU detects trouble, the tire pressure warning lamp comes on and tire pressure monitor is cancelled
at the same time. At this time, the ECU records a DTC in memory.
Connect terminals Tc and CG of the DLC3 to make the tire pressure warning lamp blink and output the DTC.

Tc and CG Terminal Circuit
CIRCUIT DESCRIPTION
DTC output mode is set by connecting terminals TC and CG of the DLC3.
The DTCs are indicated by blinking of the tire pressure warning lamp.
WIRING DIAGRAM
HINT:
When each warning lamp stays blinking, a ground short in the wiring of terminal TC of the DLC3 or an internal
ground short in each ECU is suspected.
