Pinpoint Test C: The Adjustable Pedals Only Move in 1 Second Intervals
Refer to Wiring Diagram Set 127, Adjustable Pedals for schematic and connector information. Diagrams By Number
Normal Operation
The Steering Column Control Module (SCCM) uses a Hall-effect switch attached to the pedal motor to identify the current pedal position. The SCCM sends a reference voltage along the sensor feed circuit, through the Hall-effect switch and back to the SCCM along the signal return circuit.
When the following DTCs are set, the adjustable pedals will enter a "jog mode". When the pedals are in jog mode, the memory system recall will not function from either the Remote Keyless Entry (RKE) transmitter or the memory SET switch buttons. When the pedals are actuated using the adjustable pedal switch, the motor will move the pedals for one second in the direction selected regardless of the length of time the button is actually pressed.
If the vehicle is not equipped with the memory feature and the SCCM is incorrectly configured, the SCCM may expect to receive pedal position information when the vehicle is not equipped to provide it. If this happens, the adjustable pedals will enter a "jog mode" similar to if a fault were present in the adjustable pedal position sensor circuits.
- DTC B1368:11 (Adjustable Pedal Position Feedback Sensor: Circuit Short to Ground) - This DTC sets if the SCCM detects a short to ground on the Hall-effect sensor feed and/or return circuits when the ignition is ON.
- DTC B1368:12 (Adjustable Pedal Position Feedback Sensor: Circuit Short to Battery) - This DTC sets if the SCCM detects a short to voltage on the Hall-effect sensor feed and/or return circuits when the ignition is ON.
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Adjustable pedal motor
- SCCM
- Incorrect SCCM configuration

NOTICE: Use the Flex Probe Kit for all test connections to prevent damage to the wiring terminals. Do not use standard multi-meter probes.
-------------------------------------------------
C1 CHECK THE SCCM DTCs
- Review the SCCM DTCs retrieved during Inspection and Verification.
- Were DTCs B1368:11 or B1368:12 retrieved?
Yes
GO to C2.
No
If no DTCs were retrieved, CONFIGURE the SCCM using as-built data. TEST the system for normal operation. If DTCs B1369:09, B137D:18, 19, or 71 were retrieved, REFER to the DTC chart Diagnostic Trouble Code Tests and Associated Procedures. For all other SCCM DTCs, REFER to the SCCM DTC chart in Steering Column Switches Testing and Inspection.
-------------------------------------------------
C2 CHECK THE SCCM HALL-EFFECT CIRCUITS FOR AN OPEN
- Ignition OFF.
- Disconnect: Adjustable Pedal Motor C2159 .
- Disconnect: SCCM C2414C .
- Measure the resistance between SCCM C2414C, harness side and adjustable pedal motor C2159, harness side as indicated in the following chart:
- Are the resistances less than 5 ohms?
Yes
GO to C3.
No
REPAIR the affected circuit(s). CLEAR the DTCs. REPEAT the self-test.
-------------------------------------------------
C3 CHECK THE SCCM HALL-EFFECT CIRCUITS FOR A SHORT TO GROUND
- Measure the resistance between ground and:
- SCCM C2414C-6, circuit LPP06 (YE/BU), harness side.
- SCCM C2414C-3, circuit RPP06 (GN), harness side.
- Are the resistances greater than 10,000 ohms?
Yes
GO to C4.
No
REPAIR the affected circuit(s). CLEAR the DTCs. REPEAT the self-test.
-------------------------------------------------
C4 CHECK THE SCCM HALL-EFFECT CIRCUITS FOR A SHORT TOGETHER
- Measure the resistance between SCCM C2414C-3, circuit RPP06 (GN), harness side and SCCM C2414C-6, circuit LPP06 (YE/BU), harness side.
- Is the resistance greater than 10,000 ohms?
Yes
GO to C5.
No
REPAIR the affected circuit(s). CLEAR the DTCs. REPEAT the self-test.
-------------------------------------------------
C5 CHECK THE SCCM HALL-EFFECT CIRCUITS FOR A SHORT TO VOLTAGE
- Ignition ON.
- Measure the voltage between ground and:
- SCCM C2414C-6, circuit LPP06 (YE/BU), harness side.
- SCCM C2414C-3, circuit RPP06 (GN), harness side.
- Is any voltage present?
Yes
REPAIR the affected circuit(s). CLEAR the DTCs. REPEAT the self-test.
No
INSTALL a new adjustable pedal motor and bracket assembly. REFER to Accelerator Pedal - Adjustable, Exploded View in Acceleration Control Accelerator Pedal - Adjustable, Exploded View. CLEAR the DTCs. REPEAT the self-test.
If DTC B1368:11 or B1368:12 return, INSTALL a new SCCM. REFER to Steering Column Switches Service and Repair. CLEAR the DTCs. REPEAT the self-test.
