Introduction:
Some 2019 – 2020 model year Camry vehicles may exhibit a sudden drop in heater performance ~27°F (15°C) when the vehicle is driven in ambient temperatures below -4°F (-20°C) and coolant temperature is 158°F (70°C) – 172°F (78°C). The Engine Control Module (ECM) (SAE term: Powertrain Control Module/PCM) logic has been modified to address this condition. Follow the Repair Procedure in this bulletin to address this condition.
APPLICABLE WARRANTY:
This repair is covered under the Toyota Federal Emission Warranty. This warranty is in effect for 96 months or 80,000 miles, whichever occurs first, from the vehicle’s in-service date. Warranty application is limited to occurrence of the specified condition described in this bulletin.
Repair Procedure:
1. Confirm the condition exists. Does the vehicle exhibit a sudden drop in heater performance ~27°F (15°C) when the vehicle is driven in ambient temperatures below -4°F (-20°C) and coolant temperature is 158°F (70°C) – 172°F (78°C)?
YES — Continue to step 2.
NO — This bulletin does NOT apply. Continue diagnosis using the applicable Repair Manual.
2. Use Techstream to confirm if the ECM (PCM) calibration has been updated and check for the Authorized Modifications Label affixed to the vehicle in the location shown below. Is the calibration ID listed in Techstream and on the label the latest ECM (PCM) calibration?
YES — This bulletin does NOT apply. Continue diagnosis using the applicable Repair Manual.
NO — Continue to step 3.
3. Flash reprogram the ECM (PCM).
4. Prepare and install the Authorized Modifications Label.
A. Using a permanent marker, enter the following information on the label:
ECM (PCM) part number [Refer to the Parts Information section for the NEW PART NUMBER].
Calibration ID(s) [Refer to the Calibration Information section for the NEW CALIBRATION ID].
Dealer Code.
Repair Date.
Change Authority [This bulletin number].
B. Install the Authorized Modifications Label onto the vehicle at the location shown in Figure 1. The Authorized Modifications Label is available through the MDC, P/N 00451-00001-LBL.
5. Test-drive the vehicle to confirm proper heater performance, especially if the ambient temperatures ae below -4°F (-20°C) and coolant temperature is 158°F (70°C) – 172°F (78°C).
