Parts Information
Required Tools & Equipment
Inspection Procedure A
If the vehicle is currently exhibiting a "no start" condition, refer to the Technical Information System (TIS) for the diagnostic procedure.
^ 2005 model year Corolla or Matrix Repair Manual: Engine/Hybrid System - Engine Control -"SFI System (1ZZ-FE): Basic Inspection".
^ 2006 or 2007 model year Corolla or Matrix Repair Manual: Engine/Hybrid System - Engine Control - "1ZZ-FE Engine Control System: SFI System: Basic Inspection".
NOTE:
When the "no start" condition is related to the ECM (PCM) issue, there will be NO spark or injector pulse during cranking. Also, TIS Techstream may fail to initialize with the engine ECM (PCM).
Inspection Procedure B
If the vehicle is currently exhibiting a M.I.L. "ON" with DTC P0601, P0606, and/or P0607 set with the ECM (PCM) in fail-safe mode, refer to TIS:
^ 2005 model year Corolla or Matrix Repair Manual, Engine/Hybrid System - Engine Control -"SFI System (1ZZ-FE): P0601, P0604, P0606, P0607, P0657 Actuator Supply Voltage Circuit/open"
^ 2006 or 2007 model year Corolla or Matrix Repair Manual, Engine/Hybrid System - Engine Control - "1ZZ-FE Engine Control System: SFI System: P0601: Internal Control Module Memory Check Sum Error"
^ 2006 or 2007 model year Corolla or Matrix Repair Manual, Engine/Hybrid System - Engine Control - "1ZZ-FE Engine Control System: SFI System: P0606: ECM / PCM Processor"
^ 2006 or 2007 model year Corolla or Matrix Repair Manual, Engine/Hybrid System - Engine Control - "1ZZ-FE Engine Control System: SFI System: P0607: Control Module Performance"
Prior to condemning the ECM (PCM), confirm NO problems exist with the following circuits/components:
^ Tail and stop light bulb operation.
^ Secure connection at connector R9 (Rear Combination Light LH).
^ Secure connection at connector Rh (Rear Combination Light RH).
^ Improper installation and/or operation of a trailer towing wire harness kit.
^ Sensor operation and circuit integrity for all 5V reference circuits:
VC, IGF, THA, THW, VTA1, VT2, VPA1, VPA2, VCPA, VCP2, PPMP
If a problem is diagnosed with any of the above components/circuits, repair the condition and confirm if the DTC(s) resets. ECM replacement may not be necessary. If NO other problems are found, replace the ECM (PCM).
Repair Procedure
1. Replace the ECM (PCM). Refer to TIS:
^ 2005 model year Corolla or Matrix Repair Manual, Engine/Hybrid System - Engine Control - "ECM (1ZZ-FE/2ZZ-GE): Replacement".

^ 2006 or 2007 model year Corolla or Matrix Repair Manual, Engine/Hybrid System - Engine Control - "1ZZ-FE Engine Control System: ECM Installation".
2. Register the VIN into the replacement ECM (PCM).
Refer to the Technical Information System (TIS):
^ 2005 model year Corolla or Matrix Repair Manual, Engine/Hybrid System - Engine Control - "SFI System (1ZZ-FE/2ZZ- GE): Registration".
^ 2006 or 2007 model year Corolla or Matrix Repair Manual, Engine/Hybrid System - Engine Control - "1ZZ-FE Engine Control System: SFI System: Registration".
