Suzuki Trouble Code Info

Suzuki: Diagnostic Trouble Codes

86–95 Samurai, Swift & 89 Sidekick

NOTE: This information does not apply to carberated engines, as they will not have a check engine light and no codes are retrievable. DTCs may be accessed by installing a spare fuse into the fuse box diagnostic terminal, located under the LH side of the instrument panel, then turning the ignition On.

90–95 Sidekick

DTCs may be accessed by installing a jumper wire between diagnostic check connector terminals B and C, located in the RH rear of the engine compartment, then turning the ignition On.

96–00

Accessing DTCs must be done through the Data Link Connector (DLC), located under the LH side of the instrument panel, using a Suzuki (Tech-1) scan tool or an OBD II generic scan tool.

Reading trouble codes

The instrument panel Check Engine lamp displays the DTCs. In normal operation the lamp will light when the ignition is turned On. However, two different lamp functions can occur when the engine is started. The lamp may turn off immediately, indicating there is no fault at that time, or stay lit, informing the vehicle operator that there is a system failure. If the lamp stays lit a DTC will be stored in the ECM memory. When a DTC is accessed from the ECM memory the Check Engine lamp will flash in a series, indicating the DTC number. When multiple system failures occur applicable DTCs will be indicated three times each. DTCs will continue to flash as long as the ignition is On, and the diagnostic switch terminals are grounded.

Clearing Codes

DTCs may be erased by disconnecting and isolating the battery ground cable for more than 60 seconds, or after 50 key cycles if the malfunction has not recurred.

On models with OBD II, the DTCs may be cleared with the scan tool, following the tool manufacturer’s instructions.
