Pinpoint Test K: P062C

WARNING: This page is about a different car, the 2021 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.

Normal Operation and Fault Conditions

The TCM and the ABS module communicate over HS-CAN1. Key information the ABS module sends to the TCM include vehicle speed and brake pedal position.

DTC Fault Trigger Conditions

DTC	Description	Fault Trigger Condition
TCM P062C:00	Internal Control Module Vehicle Speed Performance: No Sub Type Information	This DTC indicates a fault with the OSS sensor or VSS, or a correlation error between the two sensors.

Possible Sources

OSS sensor
VSS
Incorrect gear ratio
ABS
TCM

K1 VERIFY THE SCAN TOOL COMMUNICATES WITH THE ABS (ANTI-LOCK BRAKE SYSTEM) MODULE

Ignition ON.

Using diagnostic scan tool, carry out the network test.

Did the ABS module pass the network test?

Yes

GO to K2

No	To diagnose the ABS module does not communicate with the scan tool, REFER to: Controller Area Network (CAN) Module Communications Network .

K2 CHECK THE TCM (TRANSMISSION CONTROL MODULE) FOR DIAGNOSTIC TROUBLE CODES (DTCS)
- Using a diagnostic scan tool, carry out the TCM self-test.
Are any OSS sensor diagnostic trouble codes (DTCs) present?

Yes RESOLVE all OSS sensor diagnostic trouble codes (DTCs) first. REFER to the DTC Chart.

No GO to K3

K3 CHECK THE ABS (ANTI-LOCK BRAKE SYSTEM) MODULE FOR DIAGNOSTIC TROUBLE CODES (DTCS)
- Using a diagnostic scan tool, carry out the ABS module self-test.
Are any VSS diagnostic trouble codes (DTCs) present?

Yes RESOLVE all VSS diagnostic trouble codes (DTCs) first. REFER to: Anti-Lock Brake System (ABS) and Stability Control .

No GO to K4

K4 VERIFY THE CORRECT AXLE GEAR RATIO IS INSTALLED IN THE VEHICLE

With the vehicle in NEUTRAL, position it on a hoist. REFER to: Jacking and Lifting - Overview .

With the vehicle in NEUTRAL, rotate the driveshaft by hand and count the number of driveshaft rotations for 1 rotation of the tires. That is the gear ratio installed in the axle.

Ignition ON.

Using a diagnostic scan tool, view the gear ratio in the vehicle configuration.

Does the installed gear ratio match the configured gear ratio?

Yes

GO to K5

If available, UPDATE the vehicle configuration to match the installed gear ratio. Otherwise, INSTALL a new ring and pinion of the correct gear ratio. On 4WD vehicles, make sure the front and rear gear ratios match. REFER to: Differential Carrier . REFER to: Differential Carrier . REFER to: Differential Carrier .

K5 RECHECK THE TCM (TRANSMISSION CONTROL MODULE) FOR DTC P062C
- Using a diagnostic scan tool, clear all TCM diagnostic trouble codes.
- Road test the vehicle.
- Using a diagnostic scan tool, carry out the TCM self-test.
Is DTC P062C present?

Yes GO to K6

No The concern is not present at this time. It might have been caused by high network traffic or by an intermittent fault.

K6 CHECK FOR CORRECT TCM (TRANSMISSION CONTROL MODULE) OPERATION

Ignition OFF.

Disconnect and inspect the TCM connector.

Repair:
- corrosion (install new connector or terminals - clean module pins)
- damaged or bent pins - install new terminals/pins
- pushed-out pins - install new pins as necessary

Connect the TCM connector. Make sure it seats and latches correctly.

Using a diagnostic scan tool, program the TCM with the latest calibration. REFER to: Module Programming .

Carry out the transmission strategy download. REFER to: Transmission Strategy Download .

Road test the vehicle.

Using a diagnostic scan tool, carry out the TCM self-test.

Is DTC P062C present?

Yes

CHECK for an applicable TSB, GSB, SSM, or FSA. If a service bulletin exists for this concern, discontinue this test and follow bulletin instructions. If none address this concern, INSTALL a new TCM. REFER to: Transmission Control Module (TCM) . CARRY OUT the transmission strategy download. REFER to: Transmission Strategy Download .

No	The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
