Pinpoint Test J : DTC P062C
WARNING: This page is about a different car, the 2020 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
- Refer to TRANSMISSION CONTROLS - 10R80
for schematic and connector information.
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
- J1 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 J2 No To diagnose the ABS module does not communicate with the scan tool, REFER to: Communications Network . - J2 CHECK THE TCM (TRANSMISSION CONTROL MODULE) CONTINUOUS MEMORY DIAGNOSTIC TROUBLE CODES (CMDTCS)
- Using a diagnostic scan tool, carry out the TCM self-test.
- Clear the DTCs.
- Wait 10 seconds.
- Repeat 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 Diagnostic Trouble Code (DTC) Chart . No GO to J3 - J3 CHECK THE ABS (ANTI-LOCK BRAKE SYSTEM) MODULE 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 J4 - J4 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, monitor PCMPID AXLECC_STAT.
Does PCMPID AXLECC_STAT match the measured gear ratio?
Yes GO to J5 No Reconfigure the PCM with the correct gear ratio. REFER to: Module Configuration - System Operation and Component Description . - J5 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 J6 No The concern is not present at this time. It might have been caused by high network traffic or by an intermittent fault. - J6 CHECK FOR CORRECT TCM (TRANSMISSION CONTROL MODULE) OPERATION
- Ignition OFF.
- Disconnect and inspect TCM C1822 and all related inline connectors.
- 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
- Reconnect TCM C1822 and all related inline connectors. Make sure they seat and latch 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 .
- Operate the system and verify the concern is still present
Is the concern still present?
Yes CHECK OASIS for any applicable TSBs. If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no TSBs 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.
