Electronic Diagnosis

How To Diagnose The Problem

1. To avoid incorrect diagnostics, this book needs to be

followed accurately. Unless stated, do not jump
directly to a section that could contain the solution.
Some important information may be missed.

2. The sections in CAPITALS and bold are the main

sections that can be found in the contents.

3. The GOTO “SECTION” means to continue to check

going to the “section”.

4. The GOTHROUGH “SECTION” means to go

through the “section” and then to go back to the place
the GOTHROUGH was written.

5. BASIC ELECTRIC CIRCUITS:

You should understand the basic theory of electricity.
This includes the meaning of voltage, amps, ohms,
and what happens in a circuit with an open or shorted
wire. You should also be able to read and understand
wiring diagrams.

Check Trans Indicator

Find CHECK TRANS indicator and verify if it is
A. Flashing: GOTO DIAGNOSTIC CHECK.
B. Staying on: GOTHROUGH CHECK TRANS

CHECK.

C. Is never ON when the ignition key is turned on:

GOTHROUGH CHECK TRANS CHECK

D. Is ON during 2 seconds at ignition but OFF after:

Normal operation. No DTC or malfunction.

Diagnostic Check

This test determines if the transmission or its inputs,
outputs, connections, or sensors are failing.

1. Connect the Tech2: GOTHROUGH Tech2 OBD II

CONNECTION.

2. Turn on the ignition but not the engine.

3. Push “F2” on Tech2 to see the Diagnostic Trouble

Code (DTC):

4. Do you have a DTC?

YES: write down all code numbers and do the DTC
CHECK
NO: the DTC can not help you finding the problem.

1. GOTHROUGH “CHECK TRANS” CHECK

2. IF it is flashing and the flash is 0.2 seconds ON

and 0.2 seconds OFF, this means that you should
have a DTC stored. Please recheck GOTO
DIAGNOSTIC CHECK and if you find the same
problem, replace the Powertrain Control Module
(PCM).

1. Indicator it is ON during 2 seconds at ignition (or when

the engine is cranked) but it is OFF after the engine
starts. The indicator is working normally GOTO

Normal

C07RW047

2. Indicator it is flashing and the flash is 0.2 seconds ON

and 0.2 seconds OFF always when ignition is on
(engine cranked or not). This means that there is a
malfunction. GOTO DIAGNOSTIC CHECK.

Abnormal

C07RW048

3. Indicator it is staying ON always when Ignition is ON.

1. This means that connection between the lamp

and the PCM is shorted to ground.

2. Verify if instrument panel terminal 3 of connector

I–9 is shorted to ground.

3. Verify if the PCM connector J1 (RED) terminal

A14 is shorted to ground.

4. Verify that the instrument panel terminal 15 of

connector I–9 is connected to battery.

5. IF problem solved: GOTO CHECK TRANS

INDICATOR.

NO:Replace Powertrain Control Module (PCM).

4. Indicator it is staying OFF with the ignition ON (engine

OFF).
1. This means that connection between the lamp

and the PCM is shorted to battery or opened.

2. Verify if instrument panel terminal 3 of connector

I–9 is shorted to battery or open.

3. Verify if the PCM connector J1 (RED) terminal

A14 is shorted to battery or open.

4. Verify that the instrument panel terminal 15 of

connector I–9 is connected to battery. If not,
check the fuses and the connections voltage.

5. IF problem solved: GOTO CHECK TRANS

INDICATOR.

NO: Replace Powertrain Control Module (PCM).
