REPAIR PROCEDURE:

The Remote Engine Starter (RES) system was designed to operate at temperature ranges above -22 °F (-30 °C). Follow the procedures below to determine if RES repair is required.

Condition Diagnosis

Confirm with the customer the following:

1. Did the engine start when you started it manually, with a key or start button?
- NO - Check the Troubleshooting section of the vehicle Repair Manual.

Refer to the Repair Manual within E-TAS / TIS library:
- Division: Toyota
- Model: Camry or Camry HV or RAV4 or Tundra
- Year: 2006 or 2007
- Service Category: General
- Section: Introduction
- Keyword: Introduction: How to Troubleshoot ECU Controlled Systems: How to Proceed with Troubleshooting

- YES - Go to step 2.

2. Was the Remote Keyless Entry (RKE) functioning normally? (Did the hazard lights flash when the Lock button was pressed?)
- NO - Check the RKE section of the vehicle Repair Manual.
- YES - Go to step 3.

3. Was the temperature surrounding the vehicle below -4°F (-20°C) when the RES did not operate?
- NO - Use the RES Troubleshooting Guide to investigate other causes.
Refer to ETAS - Customization Library

- YES - Go to step 4.

4. Did the Remote Engine Starter (RES) function normally after the vehicle and surroundings warmed up to over -4 °F (-20 °C)?
- NO - Use the RES Troubleshooting Guide to investigate other causes.
Refer to ETAS - Customization Library

- YES - Go to step 5.

5. Was the temperature between -22 °F and -4°F (-30 °C and -20 °C) when the RES did NOT operate?
- NO - The RES may NOT operate in extreme cold temperatures at or below -22°F(-30°C). Explain to the customer that this is normal operation of the system and no repair is required.

- YES - If the customer confirms that temperatures were between the range of -22°F and -4°F [-30 °C and -20 °C] when the RES did NOT operate, the Gateway ECU may be at fault. If temperatures are between -22 °F and -4°F (-30 °C and -20 °C) at the time of repair, test the system before replacing the unit.

If temperatures do NOT allow for confirmation, then the unit may be replaced if the other questions do not address the issue.

If the answers to all of the above are YES, proceed to "Replace the Accessory Gateway (BUS) ECU".
1. Order an exchange unit Gateway (BUS) ECU (P/N 08190-33920) from Fujitsu Ten (refer to WAB2063).
2. Remove and replace the Accessory Gateway (BUS) ECU with the exchange part. Refer to ETAS - Customization Library.
3. Perform a Function Check.
Verify that the RES is operating properly using the Accessory Function Check section found at the end of your vehicle's RES installation instructions.

NOTE
RES registration is NOT necessary after replacing the Accessory Gateway (BUS) ECU.
