About C1134

C1134 is a manufacturer-specific chassis diagnostic trouble code. It belongs to the C-prefix family of codes, which covers chassis, braking, steering, suspension, or stability-control faults.

When C1134 is stored, the module has detected a short-circuit (voltage pulled to ground or to supply) in the monitored circuit.

Scanning & clearing: Chassis (C) codes are stored in the ABS, traction control, or stability-control modules. An enhanced or OEM-level scan tool is usually required to read and clear them.

C1134 is a manufacturer-specific code. The same code string on a different make may have a different meaning. Always confirm the code's definition against the vehicle's service information for the specific make and model under test.

Code Information

The gear shift position input, also called the transmission range or shift lever position signal, tells the control module which gear or range the driver has selected. The module uses this to enable starting only in Park or Neutral, to control reverse lamps and shift related functions, and on many vehicles the signal is a voltage or coded input from a range sensor or shift position switch. C1134 sets when the module detects that the gear shift position circuit is shorted to ground, pulling the signal low and holding it there regardless of the actual lever position. When this code is set the ve...
