NOTE:

• The TCS control unit has three memory registers. When a problem occurs, the control unit stores the Diagnostic

Trouble Code (DTC) in the first memory register. If another problem occurs, or the same problem occurs again, the con-

trol unit moves the first code to the next memory register and stores the second code in the first register. If there's a

third problem occurrence, the two existing code are moved up one register and the third code is stored in the first reg-

ister. If problems continue to occur, the oldest code is moved out of the last register and lost, and the most recent code

is stored in the first register.

• The TCS indicator light will not come on again after the engine starts unless another problem occurence is detected.

However, there will still be a code stored in the control unit's memory.

• After the repair is completed, disconnect the SCS service connector from the Service Check connector, and remove the

CLOCK (7.5 A) fuse from the under-hood fuse/relay box for at least three seconds to erase the control unit's memory.

• The control unit's memory is erased if the connector is disconnected from the control unit or if the control unit is

removed from the car.ProCarManuals.com

Troubleshooting

Tips and Precautions

Before Troubleshooting

Check applicable fuses in the appropriate fuse box.

Check the battery for damage, state of charge, and

clean and tight connections.

Check the alternator belt tension.

CAUTION:

Do not quick-charge a battery unless the battery

ground cable has been disconnected.

Otherwise you will damage the alternator

diodes.

Do not attempt to crank the engine with the bat-

tery ground cable loosely connected or you will

severely damage the wiring.

Handling Connectors

Make sure the connectors are clean and have no loose

wire terminals.

Make sure multiple cavity connectors are packed with

grease (except watertight connectors).

All connectors have push-down release type locks.

LOCKING TAB

Some connectors have a clip on their side used to at-

tach them to a mount bracket on the body or on

another component. This clip has a pull type lock.

Some mounted connectors cannot be disconnected

unless you first release the lock and remove the con-

nector from its bracket.

Never try to disconnect connectors by pulling on their

wires; pull on the connector halves instead.

Always reinstall plastic covers.

Before connecting connectors, make sure the ter-

minals are in place and not bent.

BENT TERMINAL

Check for loose retainer and rubber seals.

The backs of some connectors are packed with

grease. Add grease if needed. If the grease is con-

taminated, replace it.
