Preparatory conditions Ensure battery voltage above 11 volts. Transmission in neutral. All auxiliary equipment, including air conditioning, switched OFF.

Accessing trouble codes Trouble codes are displayed by the malfunction indicator lamp (MIL). Switch ignition ON. Check that MIL illuminates. Bridge data link connector (DLC) terminals B and D Fig. 1 . Count MIL flashes. Note trouble codes. Compare with trouble code table. Each trouble code consists of two groups of one or more flashes. A 1,5 second pause separates each trouble code group. A 3 second pause separates each trouble code. MIL flash duration: 0,3 second. For example: Two 0,3 second flashes - 1,5 second pause - one 0,3 second flash. Trouble code 21. Remove bridge wire. Switch ignition OFF. Erasing trouble codes Ensure ignition switched OFF. Disconnect battery earth lead for 120 seconds minimum. Reconnect battery earth lead. Run engine until it reaches normal operating temperature. Repeat checking procedure to ensure no data remains in ECM fault memory.

WARNING: Disconnecting the battery may erase memory from electronic units (e.g. radio, clock). Trouble code identification
