Toyota Tundra Service Manual: Precaution

PRECAUTION

1. TROUBLESHOOTING PRECAUTION

(a) When there is a malfunction in the contact point of the terminals or installation problems with parts, removal and installation of the suspected problem parts may return the system to the normal condition either completely or temporarily.

(b) In order to determine the malfunctioning area, be sure to check the conditions at the time the malfunction occurred, such as by DTC output and record it before disconnecting each connector or removing and installing parts.

(c) Since the Touch Select 2-4 and High-Low System may be influenced by a malfunction in other systems, be sure to check for DTCs in the other systems.

2. CAN COMMUNICATION SYSTEM PRECAUTION

(a) The CAN communication system is used for data communication between each of the ECUs and sensors. If there is trouble in the CAN communication line, the DTC of the communication line is output.

(b) If the DTC of the CAN communication line is output, repair the malfunction in the communication line and troubleshoot the Touch Select 2-4 and High-Low System.

(c) Since the CAN communication line has its own length and route, it cannot be repaired temporarily with the bypass wire, etc.

3. PRECAUTION FOR WHEN TESTING WITH 2-WHEEL DRUM TESTER

(a) Make sure that the transfer is in 2WD mode.
