P060A- 07: Safety Microprocessor– Integrity failure Overview: ISO Code P060A- 07 Customer Symptom Transmission Fault Lamp ON, No gearshifts , Sudden shift to neutral while driving Vehicle not cranking Fault Effects (On Vehicle) No gearshifts , Sudden shift to neutral while driving Vehicle not cranking Lamp Status (If Any) Transmission Fault Lamp ON (depending on conditions of occurrence) Fault Detection Condition This fault gets detected after Ignition On when the Main microprocessor detects a health problem in the safety microprocessor. Normal Operating Condition The Main microprocessor monitors and detects health status from the safety microprocessor. Probable Trouble Area TCU damage Healing Condition Next power ON after valid safety microprocessor health Component Details: The Problem may occur due to an internal damage to TCU. Preliminary Checks: 1) Battery voltage 2) Check for damage or back out of pins at TCU connectors. 3) Check correct fitment of ground cable connections on vehicle chassis (tightness, corrosion of mounting bolts etc.) Trouble Shooting:- Step Checks IF YES IF NO 1 Check Battery and Ignition supplies at pins 1,3and 5 respectively. Both are correct? Go to Step 2 rectify harness connections as per the circuit schematic 2 Is there any pin back out/damage/rust/oxidation observed on TCU Connector? Clean or repair or replace connector Go to Step 3 3 Fault Still Persists? Replace TCU Follow the steps again for reconfirmation DTC’s confirmation:- After rectification, clear all DTC’s and ensure the following points by referring TCU parameters using TML diagnostic tool before handing over to customer.  Drive the vehicle through all gears in both Automatic and Manual modes  Ensure no DTC is active and Transmission Fault Lamp is OFF.
