Scan Tool Testing and Procedures

TECH1 OBD II CONNECTION
In order to access OBD II Powertrain Control Module (PCM) data, use of the TECH1 scan tool is required.
1. The electronic diagnosis equipment is composed of:
- TECH1 (J-38770-1) hand-held scan tool.
TECH1 self-test adapter.
- Manufacturer's operating instructions.

2. Transmission cartridge
The cartridge (No. 7000066) must be inserted into the TECH1 for the 4L30-E transmission diagnosis.

3. Connecting the TECH1
For the TECH1 to interpret the Class 2 Data Bus used by OBD II, it is necessary to use the TECH1 application kit part #7000041 or #7000041A.
Kit part No. 7000041:
- 3000091-OBDII VIM
- 3000086-14/12 PIN VIM DLC ADAPTER

When instructed to use a voltmeter or ohmmeter within a troubleshooting procedure, use only a high-impedance DVOM (Digital Volt Ohm Meter) such as J-39200 or equivalent.
